The GitHub of prompts — for everyone

Version, test, and ship your LLM prompts like code.

Prompts drive your product, but they live in Notion docs, Slack threads, and hardcoded strings — with no history, no tests, no safety net. PromptVCS gives them version control, testing, and edge delivery.

Everything your prompts have been missing

Version control

Every prompt change is saved with full history. See who changed what, when, and why — and roll back in one click.

Diffing

Line- and word-level diffs between any two versions, with the eval-score impact shown right alongside the change.

Testing & evals

Write tests for your prompts and catch regressions before they ship — in the dashboard or your CI pipeline.

Edge delivery

Fetch the live prompt at runtime from a globally fast API. Update prompts without redeploying your app.

API, CLI & CI

A clean REST API, a pvcs CLI, and a GitHub Action that gates deploys on your eval suite.

Built for teams

Environments, roles, and per-key usage — workspace-isolated and enterprise-ready from day one.

Stop breaking production with a prompt edit

A single careless prompt change can quietly tank quality for every user. With tests on every version and an eval gate in CI, you catch regressions before they ship — and when something slips through, you roll back instantly instead of scrambling.
