The Infrastructure for
Prompt Engineering
Stop managing prompts in chat logs and spreadsheets. Write, version, test, and deploy your LLM prompts with the reliability of production code.
The Agent Architect.
The First Meta-Agent.
Stop writing prompts. Start architecting intelligences.
The only engine that recursively reasons to build production-ready
cognitive architectures for you in seconds.
Works with your favorite models
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.

Senior AI Engineer @ DataFlow
"We used to manage prompts in Google Sheets. OpenPrompt gave us a real workflow. We've cut our iteration time by 40%."
Priya Patel
CTO @ BuildSmart
"The API integration is flawless. Being able to update prompts in production without a code deploy has saved our engineering team countless hours."
James Wilson
Product Lead @ Innovate Inc
"I don't need to bug developers to change the tone of our chatbot anymore. I can test variations and push the winner live myself."

Sarah Chen
ML Researcher @ TechNexus
"The versioning system is a lifesaver. Visualizing the diff between two prompt versions caught a major regression before shipping."
Michael Ross
Full Stack Dev @ StartUp.io
"Implementation took less than 10 minutes. The SDK is intuitive and the typing support is excellent. Best DX I've seen."
Emily Davis
Prompt Engineer @ CreativeAI
"Finally, a tool that treats prompt engineering as a discipline. The variable management and testing playground are exactly what we needed."
