Backfire works with the runtime you already deploy

Vercel

A Vercel function is an ephemeral process with an open outbound network. Backfire gives those invocations one authenticated egress path, so a URL that arrived in a request body is never handed straight to fetch().

Cloudflare Workers

Workers run user-triggered code at the edge with the ability to fetch almost anything. Backfire puts a validating relay between the worker and the Internet, and gives you a log that survives past the request.

AWS Lambda

Lambda functions multiply: one per endpoint, each with its own outbound code and its own credentials. Backfire collapses third-party calls into one endpoint you can key, rate-limit and audit in a single place.

GitHub Actions

CI jobs end up holding credentials for every service they touch. A relay key gives a workflow one outbound capability that can be revoked the moment a run misbehaves — and a log of exactly what it called.

Supabase Edge Functions

Edge functions are Deno processes with fetch() and little else. Backfire gives them a target-validated path out plus a record of what each invocation did, without adding a database round trip to the call path.

n8n

Automation workflows are where credentials quietly multiply: every HTTP node holds its own secrets and nothing records what a run actually called. A relay key centralises the outbound path across all of them.
