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.
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?
See how we compare to the alternatives.
Git
Great for code, but hard to visualise prompts.
Spreadsheets
No versioning, no testing, messy.
Other Tools
Often lock you into specific models.
OpenPrompt
Versioning, testing, model-agnostic API.
From idea to
production_ready
Stop managing prompts in spreadsheets. Adopt a professional workflow designed for the AI era.
Draft & Iterate
Craft your prompt with our variable-aware editor. Iterate rapidly with instant previews and token estimation.
Evaluate Performance
Run batch tests against varied datasets. Compare model outputs side-by-side to ensure quality and safety.
Ship Execution
Push to edge. Consume via API. Rollback instantly if needed. No more hardcoded strings in your codebase.
async function getAgentPrompt(slug: string) {
const res = await fetch(`https://api.openprompt.dev/v1/prompt`, {
headers: {
'x-api-key': process.env.OP_API_KEY,
'slug': slug
}
});
const data = await res.json();
return data.content;

Alex Rivera
"We used to manage prompts in Google Sheets. OpenPrompt gave us a real workflow. We've cut our iteration time by 40% and finally have a source of truth for our LLM interactions."
Priya Patel
"The API integration is flawless. Being able to update prompts in production without a code deploy has saved our engineering team countless hours. It's essentially a CMS for our AI logic."
James Wilson
"I don't need to bug developers to change the tone of our chatbot anymore. I can test variations, compare results, and push the winner live myself. It empowers the whole product team."
Sarah Chen
"The versioning system is a lifesaver. Being able to visualize the diff between two prompt versions and their corresponding outputs helped us catch a major regression before shipping."
Michael Ross
"Implementation took less than 10 minutes. The SDK is intuitive and the typing support is excellent. Best developer experience I've had with an AI tool."
Emily Davis
"Finally, a tool that treats prompt engineering as a discipline. The variable management and testing playground are exactly what professional prompt engineers need."
