Everything you need to
Master Prompt Engineering

Built for developers, researchers, and prompt engineers who demand precision, control, and scalability.

Version Control

Treat prompts like code. Track changes, diff versions, and rollback instantly.

Collaborative

Real-time multiplayer editing for your entire prompt engineering team.

Zero-Latency API

Deploy to our edge network. Cache responses. <50ms global latency.

Model Agnostic

Switch providers (OpenAI, Anthropic, Mistral) without changing a line of code.

Testing Suite

Run regression tests against your prompts before deploying to production.

Role Security

Granular permissions for viewing, editing, and deploying prompts.

Instant Forking

Fork any prompt to your workspace to experiment safely.

Why OpenPrompt?

We're replacing the "Spreadsheet & Chat Log" era of prompt engineering with a professional development environment.

The Old Way

Manual, error-prone, fragmented.

  • Hardcoded strings in code
  • No version history
  • Testing in production
  • Copy-pasting to Slack

The OpenPrompt Way

Automated, collaborative, scalable.

Production Grade
  • Dynamic API-based fetching
  • Instant rollbacks (v1.2 → v1.1)
  • Regression testing suite
  • Role-based access control
  • Model-agnostic syntax
  • Collaborative playground
  • Start shipping in minutes

    The fastest path from idea to deployed agent.
