Software advice
Best AI API Management Software in 2026
AI API management software is a gateway and control layer that publishes, secures, meters and documents your APIs, and that now also routes traffic from AI models, MCP servers and agents through the same policies. It adds token budgets, prompt guardrails and AI-assisted documentation or design to classic key management and rate limits. It is not an LLM provider and it does not write your backend.
Quick answer
Zuplo ranks first for small teams that want a managed gateway with AI and MCP gateways built in at a free entry price. Tyk fits teams that need self-hosted control, and Azure API Management fits organizations already on Microsoft.
API management used to mean keys, quotas and a developer portal. Now the same gateway is asked to sit between your applications and model providers, cap token spend per team, filter prompts and expose internal services to agents through MCP. Vendors have added those functions at very different depths, from a plugin on an old gateway to a product built around them. This ranking looks at what each gateway does for AI traffic, what a month costs at your volume, where requests and logs are processed, how hard it is to leave, and which kind of team each tool suits. Prices are as of October 2026.

Zuplo
Zuplo takes first place because it puts the AI features into every plan, including the free one. Its pricing page lists an MCP Gateway, an AI Gateway and a developer portal on each tier, and the AI Gateway gives every app its own policy chain with budgets and guardrails. Policies are written in TypeScript and deployed from GitHub. The trade-off is that SSO, audit logs and an uptime guarantee wait for Enterprise.
Strong on
- AI Gateway, MCP Gateway and developer portal are listed on every plan, including free
- Per-app policy chains give a chatbot and an internal agent separate budgets and guardrails
- Custom policies are plain TypeScript kept in your own repository
Weak on
- SSO, role-based access, audit logs and the uptime guarantee are Enterprise-only
- Builder is described as a solo plan, capped at 2 developer seats and 1M requests
Skip it if: Organizations that need broad built-in SSO and audit trails on a mid-priced plan, or an established partner ecosystem. Free allows 100,000 requests and 2 developer seats; Enterprise starts at $1,000 a month, annual contract.
- 2
Treblle
Treblle ranks second because it solves the part many gateways skip: knowing what your APIs actually do. It scores OpenAPI specifications before release, records requests at runtime, and generates documentation and tests from what it sees. It does not replace your gateway, which keeps it out of the first slot. Its own page says it needs zero gateway changes and lists ISO 27001 and SOC 2 audits.
Strong on
- Deploys beside an existing gateway, so there is nothing to migrate
- Rates OpenAPI specifications against standards before code ships
- Enterprise plan offers on-prem or bring-your-own-cloud deployment and SSO
Weak on
- No gateway, rate limiting or key management of its own
- Core is capped at 5 APIs and 30 days of data retention
Skip it if: Teams looking for a single product to route, authenticate and throttle traffic, or buyers who want a free plan. Core covers 5 APIs and 5 million requests monthly; Growth and Enterprise are quoted. HQ taken from Delaware entity.
- 3
Tyk
Tyk sits third because it gives engineers the most control over where the gateway runs. Cloud, hybrid and self-managed deployment are all sold, the Gateway is open source, and Core pricing counts APIs instead of calls. Tyk AI Studio covers model governance and an MCP Gateway is listed. Exact plan prices are not published, which makes budgeting a conversation with sales.
Strong on
- Open source Gateway and Pump are free to run under the MPL 2.0 license
- Core plan is priced by APIs managed, with no cap on API calls
- Offers cloud, hybrid and self-managed deployments of one product
Weak on
- No published prices for Core, Professional or Enterprise
- Developer portal, operator and multi-data-centre control sit on paid licensed plans
Skip it if: Teams that want to read a price, sign up and ship in an afternoon without talking to a vendor. Core is priced by APIs managed, quoted on request; the open source Gateway and Pump are free (MPL 2.0).
- 4
Gravitee
Gravitee fills fourth place with an unusually broad scope for the money. One subscription covers API gateways, event management for Kafka and MQTT, identity and an Agent Management module with LLM, MCP and A2A proxies. Users are unlimited. The $2,500 entry point is the highest published floor on this list, so it fits budgets with a platform team and not a side project.
Strong on
- Agent Management module proxies LLM, MCP and A2A traffic and is available on every tier
- Unlimited users on every plan, with free onboarding and a customer success manager
- Self-hosted, hybrid or full SaaS deployment with the same modules
Weak on
- Entry plan starts at $2,500 a month and no free plan is listed
- Capacity is shared across modules, and each added module needs its own
Skip it if: Startups and solo developers with a few APIs, who would pay for modules they never switch on. Planet covers 50 million requests, unlimited users and one module; Galaxy is quoted, with 100 million.
- 5
DreamFactory
DreamFactory lands fifth because it manages a different problem: generating governed APIs from databases and legacy systems, then locking them down. It creates REST endpoints automatically, adds roles, API keys and scripting, and advertises a drop-in MCP server for language models. Pricing is high for a small deployment, and gateway features for AI model traffic are not its focus.
Strong on
- Generates REST endpoints from a database without hand-written code
- Unlimited roles, keys, API creation and requests on paid plans
- Ships as Linux, Docker or Kubernetes installs, with a free open source edition
Weak on
- Lite is limited to a single database connector, and Oracle, Snowflake and DB2 need Professional
- Offers no LLM routing or token budgets listed on its pricing page
Skip it if: Teams that want to meter LLM calls or manage APIs built from application code. Lite allows one connector; Professional is $4,000 a month; an open source edition is free.
- 6
Kong
Kong comes sixth because its AI Gateway is the most protocol-aware one here, with a single endpoint for LLM, MCP and A2A traffic and analytics on tokens and errors. The Konnect control plane manages gateways you run yourself. Its pricing page splits AI, API and Event management into separate plans, so a full estate costs more than the entry figure suggests.
Strong on
- One control plane governs LLM, MCP and A2A traffic with built-in analytics
- Gateways can run on-prem through Docker while Konnect manages them
- Plugin library covers authentication, traffic control and transformations
Weak on
- AI, API and event management are priced as separate plans on the pricing page
- Plugin configuration is Kong-specific and does not carry over to other gateways
Skip it if: Small teams with one or two APIs who do not want a control plane to operate. Plus has a 30-day free trial; Enterprise is a custom annual contract, quoted on request.
- 7
Postman is seventh because it manages the lifecycle around the API and not the traffic through it. Specifications, mock servers, collections, monitors and documentation live in shared workspaces, and Agent Mode and an MCP Server give assistants API context. Fabric is its separate product for routing and governing AI traffic. AI use is metered in credits, which makes heavy use a budget line.
Strong on
- Free plan covers the API client, specs, mock servers and native Git
- Agent Mode and a Postman MCP Server connect assistants to your API collections
- Team plan adds role-based access control at $19 per user per month
Weak on
- AI features draw on monthly credits, 100 on Free and 400 on paid plans
- Runtime gateway features live in Fabric, which is sold separately from the workspace
Skip it if: Buyers who need a production gateway for rate limiting and authentication in front of live traffic. Free includes 100 AI credits; Team is $19 per user monthly, billed annually; Enterprise is quoted.
- 8
Google Cloud Apigee
Apigee holds eighth place as the veteran enterprise option. It handles REST, SOAP, GraphQL and gRPC, offers pay-as-you-go or subscription billing and a 60-day sandbox, and Gemini Code Assist in Apigee generates OpenAPI specifications from natural language. Policies are Apigee-specific, onboarding is heavy, and the per-call price plus environment charges are harder to forecast than flat tiers.
Strong on
- Supports REST, SOAP, GraphQL and gRPC in one platform
- Gemini Code Assist drafts OpenAPI specifications and mock servers from prompts
- 60-day free sandbox and a pay-as-you-go option with no sales call
Weak on
- Environments are billed per hour per region on top of per-call charges
- Monetization and advanced API security are paid add-ons
Skip it if: Small teams or those outside Google Cloud, where Apigee's setup and billing model weigh heavily. Pay-as-you-go also charges for environments per hour; Extensible proxies cost $100 per million calls, and subscription plans are quoted.
- 9
Azure API Management
Azure API Management ranks ninth because its AI gateway is good but tied to the Azure account. Microsoft documents token quotas, load balancing across model endpoints, a unified model API in preview, import of Foundry and Bedrock models, and exposing REST APIs as MCP servers. Capabilities vary by tier, and the AI gateway extends the existing product instead of being a separate one.
Strong on
- AI gateway features cover token limits, load balancing and monitoring of model calls
- Can expose existing REST APIs as MCP servers and manage A2A agent APIs
- Free for up to 100,000 requests when created as an AI Gateway in Azure AI Foundry
Weak on
- Feature availability differs between classic and v2 tiers, so check the tier matrix
- Anthropic Messages API support is listed only for the v2 tiers
Skip it if: Teams running most workloads outside Azure, who would still need to adopt Azure identity and billing. Six tiers from Consumption to Premium; prices come from a calculator, so none are quoted here.
- 10
Amazon API Gateway
Amazon API Gateway closes the list because it manages APIs well but has little AI-specific tooling on its documentation page. It creates REST, HTTP and WebSocket APIs, bills only for calls and data transfer with no upfront commitment, and fits naturally in front of AWS services. Token budgets, prompt filters and an agent gateway are not described there, so AI governance means other AWS services.
Strong on
- No minimum fees or upfront commitment, and you pay only for calls received
- Supports REST, HTTP and WebSocket APIs in one managed service
- Free tier includes one million REST and one million HTTP API calls monthly for 12 months
Weak on
- Documentation lists no LLM routing, token budgets or prompt guardrails
- Developer portal, monetization and governance need extra AWS services or other tools
Skip it if: Teams outside AWS, or those that want built-in AI traffic governance and a ready-made developer portal. Billed per call received plus data out; free tier gives one million REST and HTTP calls monthly for 12 months.
- 11
Traefik Hub
Traefik Hub ranks eleventh because it suits a narrower buyer than the leaders. It builds on the open-source Traefik Proxy and adds API management driven by Kubernetes custom resources, plus an AI Gateway and an MCP Gateway sold as add-ons. Nothing is priced publicly and the model assumes Kubernetes. Teams that run clusters and want policy kept in Git will find it natural.
Strong on
- Upgrade path from the free Traefik Proxy by license change, with no binary swap
- AI Gateway pairs multi-LLM routing with guardrails, semantic caching and token cost attribution
- Air-gapped mode and FIPS 140-3 options are listed for restricted environments
Weak on
- Hub prices are not published; both tiers point to a pricing request
- AI Gateway and MCP Gateway appear as add-ons, not part of the base tier
Skip it if: Teams without Kubernetes, or buyers who want a hosted gateway and a card-priced plan. Traefik Proxy is open source; Hub gateway and API management tiers show "get pricing" only.
- 12
MuleSoft Anypoint Platform
MuleSoft Anypoint Platform ranks twelfth because its entry cost is far above the other gateways here. Its pricing page now bundles API and AI governance, agent management, integration and document processing under one credit currency, starting at $2,000 a month, with token budgets and a full audit trail on the governance package. That breadth pays off for large integration estates, and is excess for a team that only needs a gateway.
Strong on
- One shared credit pool covers API management, agent governance, integration and document processing
- Governance package lists out-of-the-box policies, guardrails and token budgets with cost controls
- Usage dashboards show credits used and forecast, with alerts before a threshold is reached
Weak on
- Entry price is $2,000 a month, high for a team that only needs a gateway
- Every package is sold through sales contact, and pre-commit needs $50,000 a year
Skip it if: Startups and small API teams that need a self-serve gateway with a low monthly bill. Packages include shared Mule Credits; the pre-commit model has a $50,000 annual minimum.
How these AI API management software were judged
What does an AI gateway add to ordinary API management?
The additions fall into four jobs: routing calls to model providers, capping token spend, filtering prompts and responses, and exposing services to agents through MCP. Zuplo describes per-app policy chains with budgets, prompt-injection and PII guardrails and semantic caching. Kong unifies LLM, MCP and A2A traffic under one control plane, and Azure API Management lists token quotas, load balancing across endpoints and import of REST APIs as MCP servers. Treblle and Postman lean toward documentation and testing assistance. Ask each vendor to show a blocked prompt and a budget cut-off live, because a feature list hides how shallow some of these controls are.
How much does API management cost at 10 million requests a month?
The billing unit decides the answer. Apigee lists $20 per million calls for its Standard proxy up to 50 million, while Amazon API Gateway bills only for calls received and data transferred out. Zuplo charges nothing up to 100,000 requests a month, $25 on Builder and quotes from $1,000 a month on Enterprise. Gravitee starts at $2,500 a month for 50 million requests, and DreamFactory sells $1,500 and $4,000 plans billed annually. Tyk prices its Core plan by number of APIs, with no call limit. Add portal, SSO and support tiers before you compare totals.
Where do your API traffic and prompts get processed?
A gateway sees every request body, and an AI gateway also sees prompts and model answers. Self-hosting changes that picture: Tyk runs on-prem or in your cloud, DreamFactory ships Linux, Docker and Kubernetes editions, and Zuplo lists self-hosted and dedicated options besides managed edge. Treblle states it undergoes annual ISO 27001 and SOC 2 audits and offers on-prem or bring-your-own-cloud deployment on Enterprise. Whether a vendor stores prompts or uses them for training was not found on the pages reviewed for most entries, so request the data processing terms in writing before routing production traffic.
How hard is it to move APIs off one gateway to another?
Most of the lock-in sits in policies, plugins and portal content rather than in the proxy itself. Kong plugins, Apigee XML policies and Azure policy expressions have no direct equivalent elsewhere, and Zuplo's TypeScript policies exist only in its runtime. OpenAPI definitions are the part that travels, which is why Treblle and Postman, both built around specifications, carry less exit risk. Tyk lists its gateway under the MPL 2.0 license and DreamFactory has an open source edition, so you can keep running them without a contract. Keep specifications in Git and test your policies as code.
Which API management tool suits which kind of team?
A startup shipping its first public API will start with Zuplo, since the free tier covers early traffic. Platform teams that must run in their own network look at Tyk, Gravitee or Kong. Organizations that already hold an Azure or AWS commitment usually stay with Azure API Management or Amazon API Gateway for billing and identity reasons. Companies with a large gateway estate and no insight into it can add Treblle, and teams that need REST access to legacy databases quickly can use DreamFactory. Postman suits groups whose real problem is design, testing and documentation.
How to choose an AI API management tool in three steps
- Count your APIs, your monthly requests and your AI calls. Write down how many APIs you publish, how many requests they handle in a busy month, and how many of those are calls to model providers or MCP servers. The numbers pick the pricing model: per-API plans such as Tyk Core, per-million-call plans such as Apigee, module bundles such as Gravitee, or flat tiers such as Zuplo. Add the cost of a developer portal and single sign-on, which several vendors keep on enterprise tiers. A gateway that looks cheap at a thousand calls can cost more than the rest of your stack at a hundred million.
- Run one real API and one AI workload through a trial. Zuplo and Postman have free plans, Kong offers a 30-day trial, and Apigee gives a 60-day sandbox. Put a production-shaped API behind the gateway, then route one model call through its AI layer with a token budget and a deliberately bad prompt. Note how long setup took, whether the logs show the full request, and whether the budget actually blocked a call. Ask a developer who did not configure the trial to read the error messages, because those are what your team will live with.
- Check hosting, contract terms and the exit before signing. Decide whether traffic may leave your network, then rule out vendors whose managed plan is the only option. Read the data processing terms for prompts and logs, because privacy pages often cover websites only. Check which plan includes SSO, audit logs and an uptime guarantee, since Zuplo, for example, reserves those for Enterprise. Finally, count the policies and portal pages you would rebuild if you left, and prefer tools that keep configuration in files you control. That exit count is the most honest measure of how much a low entry price really costs.
Frequently asked questions
What is the best AI API management software in 2026?
Zuplo ranks first in this list because its AI Gateway, MCP Gateway and developer portal come with every plan and a free tier covers 100,000 requests a month. Treblle and Tyk follow for visibility and self-hosting. Large organizations often prefer Azure API Management, Apigee or Kong for their contracts and ecosystems.
Is there free AI API management software?
Yes, with limits. Zuplo's free plan allows 100,000 requests a month and 2 developer seats, Postman's Free plan includes 100 AI credits, and the Tyk Gateway and DreamFactory open source edition are free to run. Amazon API Gateway has a free tier of one million calls for up to 12 months, and Apigee offers a 60-day sandbox.
What is the difference between an API gateway and an AI gateway?
An API gateway authenticates, rate limits and routes calls to your own services. An AI gateway applies similar controls to traffic going to model providers, adding token budgets, provider switching, prompt filtering and caching. Zuplo, Kong, Tyk and Azure API Management now ship both, either as one product or as separate gateways.
Can API management tools expose my APIs to AI agents?
Several can. Azure API Management can expose a REST API as an MCP server, Zuplo and Tyk list MCP gateways, Kong governs MCP and A2A traffic, and DreamFactory advertises a drop-in MCP server. Postman has its own MCP server for agents. Test authentication on these endpoints separately, since agents call tools without a human reviewing each request.
How much does Gravitee or Kong cost?
Gravitee lists a Planet plan at $2,500 a month, with 50 million requests, unlimited users and one module, and quotes larger plans on request. Kong lists its Plus plan for AI management from $25 a month plus usage, with a 30-day free trial, and sells Enterprise on a custom annual contract.
Do I need a separate tool for API documentation and testing?
Not always. Treblle generates documentation from live traffic and scores OpenAPI specifications, and Postman covers specifications, mock servers, testing and documentation in one workspace. Gateways such as Zuplo and Tyk include a developer portal. If your gateway lacks one of these, pair it with Postman or Treblle.
Can I self-host an AI API gateway?
Yes. Tyk runs self-managed or hybrid, Gravitee offers self-hosted, hybrid and SaaS deployment, Kong lists an on-prem AI Gateway installed with Docker Compose, and DreamFactory ships Linux, Docker and Kubernetes editions. Zuplo lists a self-hosted option, and Treblle offers on-prem or bring-your-own-cloud on its Enterprise plan.
Should I choose a cloud provider's gateway or an independent one?
A provider's gateway makes sense when your backends, identity and billing already live there. Azure API Management and Amazon API Gateway integrate with their clouds, and Apigee fits Google Cloud. An independent gateway such as Zuplo, Tyk, Gravitee or Kong avoids tying your API layer to a single provider's roadmap.
