Prompt Management for AI Teams

Prompts outside your code.

The prompt management platform for AI teams. Version, test, and fetch prompts at runtime via REST API — no redeploy needed.

Request
curl "https://www.fetchprompt.dev/api/v1/prompts/welcome-email?user_name=Alice&plan=Pro" \
  -H "Authorization: Bearer fp_prod_abc123"

}

How It Works

Step 01

Create a prompt

Write your prompt in the dashboard. Use {{variables}} for dynamic content that gets filled at runtime.

Step 02

Create an API key

Generate a stage or production API key from the dashboard. Each key is scoped to one environment.

Step 03

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.

Request
curl -H "Authorization: Bearer fp_prod_abc123" \
  "https://www.fetchprompt.dev/api/v1/prompts/support-agent?company=Acme+Inc&customer_name=Alice&plan=Pro"
Response
{
  "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.
