Prompts outside your code.
The prompt management platform for AI teams. Version, test, and fetch prompts at runtime via REST API — no redeploy needed.
30,000 free API calls/month · Unlimited prompts · Full version history
curl "https://www.fetchprompt.com/api/v1/prompts/welcome-email?user_name=Alice&plan=Pro" \
-H "Authorization: Bearer fp_prod_abc123"{
"slug": "welcome-email",
"name": "Welcome Email",
"content": "Hi Alice, welcome to the Pro plan! ...",
"version": 12,
"environment": "prod"
}How It Works
Create a prompt
Write your prompt in the dashboard. Use {{variables}} for dynamic content that gets filled at runtime.
Create an API key
Generate a stage or production API key from the dashboard. Each key is scoped to one environment.
Fetch and use the prompt
Call the REST API from your app. Pass variables as query params — get back the interpolated prompt ready to send to any LLM.
curl -H "Authorization: Bearer fp_prod_abc123" \
"https://www.fetchprompt.com/api/v1/prompts/support-agent?company=Acme+Inc&customer_name=Alice&plan=Pro"{
"slug": "support-agent",
"name": "Support Agent",
"content": "You are a helpful customer support agent for Acme Inc. The customer's name is Alice and they are on the Pro plan.",
"version": 3,
"environment": "prod"
}Everything you need to manage AI prompts
Built for teams that ship AI products. Version control, environments, and a REST API — all in one place.
Version Control
Every save creates an immutable snapshot. Compare any two versions side by side and restore with one click.
Environment Separation
Stage and Production environments with one-way promotion. Test changes safely before going live.
REST API
Fetch prompts at runtime from any language or framework. Built-in caching and rate limiting included.
Variable Interpolation
Use {{variable}} syntax in your prompts. Pass values as query params at fetch time — prompts are interpolated server-side.
Instant Rollback
One-click restore to any previous version. Rollback creates a new version — history is never rewritten.
Team Collaboration
Invite prompt engineers, PMs, and domain experts to edit prompts directly — no code access needed. Role-based permissions keep things organized.

Frequently asked questions
What is FetchPrompt?
FetchPrompt is a prompt lifecycle management platform. It lets you store AI prompts outside your codebase, version them, and fetch them at runtime via a REST API.
How does environment separation work?
Each prompt can have independent content in Stage and Production environments. API keys are scoped to environments — a Stage key only returns Stage prompts.
Can non-engineers edit prompts?
Yes! Prompt engineers, PMs, and domain experts can edit prompts directly in the dashboard. Every change is versioned and can be rolled back instantly.
What languages and frameworks are supported?
FetchPrompt uses a standard REST API, so it works with any language or framework. We provide examples for Python, JavaScript, and cURL.
How does versioning work?
Every save creates a new version with a snapshot. You can view the full history, compare any two versions side by side, and restore any previous version.
Is there a free tier?
Yes! The free tier includes unlimited prompts, unlimited team members, 30,000 API calls per month, and full version history. No credit card required to get started.
