PromptRail is the infrastructure for your AI wrappers. Connect prompts to models, generate dynamic API endpoints, and track every execution—all without changing your application code.
Everything you need to manage, test, and deploy your AI integrations efficiently.
Create routes that connect prompts, models, and credentials. Switch underlying models instantly without code changes.
Auto-generate endpoints for your routes. GET for schema info, POST to execute the prompt with variables.
Built-in UI playground to test your prompts and routes with different variables before deploying to production.
Track every API call, token usage, and calculate costs per LLM provider automatically.
Store API keys and secrets securely. We handle the connection to providers like OpenAI, Anthropic, and Google.
Define input variables in your prompts. Our API validates them and passes them to the model seamlessly.
Built-in rate limiting per endpoint, token, and IP. Set custom limits or use plan defaults to prevent abuse.
Automatic enforcement of resource limits (prompts, endpoints, executions). Upgrade plans when you need more.
Real-time dashboard showing resource usage, execution counts, token consumption, and estimated costs.
Create prompts with variables and connect them to your preferred AI models and credentials.
Bundle your prompt and model into a Route to generate a unique, secure API endpoint.
Point your app to the endpoint. We handle the execution, logging, and cost tracking.
Stop fighting with different SDKs. PromptRail gives you a single, unified API for all your AI needs. Just copy the snippet and you're running in production.
Features designed for teams scaling their AI operations.
Every change to your prompt is saved as a new version. Compare diffs side-by-side to see exactly what changed, and restore any previous version instantly if something breaks.
Your application talks to a stable Endpoint. You can switch the underlying Route from GPT-3.5 to GPT-4, or change the prompt entirely, without ever touching your application code.
AI shouldn't be a black box. PromptRail gives you a complete audit trail of every interaction, ensuring compliance and enabling rapid debugging.
We log every prompt input, variable, and model response. Search and filter history to audit usage or debug issues.
Track token usage and costs down to the individual request. Know exactly which features are driving your AI bill.
Trace bad responses back to the exact prompt version and input variables that caused them. Fix hallucinations instantly.
PromptRail is flexible enough for any AI-powered application.
Manage system prompts and personas for your customer support bots.
Create routes for blog posts, social media captions, and email drafts.
Reliably extract structured JSON data from unstructured text inputs.
