PromptHub: cost, fit and limits
PromptHub is a prompt management platform made by Tethered Software Inc. that stores prompts with Git-style versioning, branches and commits, tests them side by side across models and exposes them through an API. It is aimed at prompt writers and small teams, with a free tier and per-user paid plans.
What to know first
PromptHub copies the working habits of Git: prompts are committed to branches, and the latest commit on any branch can be run or fetched through an API. Pipelines of evaluators can run on each commit or merge to catch leaks or regressions. Plans are cheap and per user, from $12 for one person. Security is the weak spot, since SOC 2 is listed as in progress.

Who PromptHub is best for
Prompt writers who think in branches
Prompts are organized with Git-based versioning and can be deployed through branches, so an experiment lives on its own branch until a merge.
Solo practitioners
Pro costs $12 monthly, or $9 billed yearly, for a single user with unlimited private prompts, 10,000 requests and full API access.
Teams that need review before release
Team at $20 per user adds permissions, evaluations and CI/CD pipelines that run on each commit or merge. Pipelines are included from this tier upward.
Non-technical colleagues who need a form
Shareable Forms can be embedded anywhere, and a Zapier integration passes variables and logs requests, so a prompt can be used without code.

What PromptHub does
- Git-based versioning
- Prompts are committed and organized with branches, and the platform pitches Git-style review and deployment through branches. Prompts are committed and organized with branches, and the platform pitches Git-style review and deployment through branches, which writers know from code.
- API for branches and heads
- A POST request runs the latest commit from any branch, a GET request fetches the current head prompt, and the team's projects can be listed programmatically.
- Evaluations and pipelines
- Evals run across test cases, and pipelines of evaluators can run on each commit or merge to catch secret leaks, profanity and regressions. Evaluation is not included on Free or Pro.
- Side-by-side model tests
- The testing section names OpenAI, Anthropic, Azure, Google, Meta, Bedrock and Mistral models for comparison, and it supports chat prompts and no-code chaining. Several models can be compared in one view.
- Generator and enhancers
- A prompt generator and enhancers help write and improve prompts. Enhancement counts are capped, from 10 on Free to 500 on Team. Each plan counts them per month.
How PromptHub handles your data
PromptHub's pricing FAQ says prompts, variables and outputs are encrypted at rest and in transit, though it writes the cipher as AES-246, which looks like a typo for AES-256. Data export is available on request, and request proxying for logging is supported. SOC 2 is listed as in progress under Enterprise, not certified, and the pages show no self-hosting. The privacy policy names Tethered Software Inc. with a New Jersey address and says nothing on retention or on training models with customer data.
Where PromptHub falls short in practice
- SOC 2 is not finished. The pricing page says SOC 2 is in progress and only under Enterprise, so security reviewers who need a report today cannot get one. Enterprise gets SSO and SAML as well.
- You bring your own API keys. The FAQ says LLM provider token costs are billed separately and you need your own keys, so the plan price covers PromptHub only, not model usage.
- Request ceilings are low. Free allows 2,000 requests a month, Pro 10,000 and Team 50,000, and the page shows no overage price, so production traffic needs an Enterprise conversation.
- Evaluations start at Team. Evaluations and Pipelines are not on Free or Pro, so the review-before-merge workflow that distinguishes the product costs $20 per user. Free and Pro users still have side-by-side and batch testing, but no automated gate.

Alternatives to PromptHub
PromptHub: common questions
What does the free PromptHub plan include?
Free is $0 with no credit card and lists unlimited team members, unlimited public prompts, 2,000 requests a month, 10 prompt enhancements and limited API access. Private prompts, full API access, evaluations and pipelines are paid features, and you supply your own LLM provider keys.
How does PromptHub versioning differ from a normal registry?
It uses Git-style concepts: prompts are committed and organized in branches, and the API can run the latest commit from any branch or fetch the head prompt. Pipelines of evaluators can run on each commit or merge, which resembles pull-request checks.
Is PromptHub SOC 2 certified?
No. The pricing page lists SOC 2 as in progress under the Enterprise plan and says the company is not certified. Prompts, variables and outputs are described as encrypted at rest and in transit, and data export is available on request.
Can I use PromptHub without writing code?
Partly. Shareable Forms can be embedded anywhere, and a Zapier integration passes variables and logs requests. The playground tests prompts side by side across providers, and prompt chaining needs no code. Calling prompts from an application still uses the API.
