Features
Everything you need to debug production failures
From capture to replay to regression test — FluxRun gives backend teams the tools to turn incidents into preventions.
Safe Replay
Reproduce production failures with recorded IO, fixed clocks, and no live side effects.
Zero Production Writes
Replay runs in an isolated environment. Your database and APIs are never touched.
Protected Payloads
Sensitive data stays encrypted. Unlock via secure agent route only when needed.
Team Workflow
Shared orgs, projects, and incident response. Everyone sees the same failure context.
Regression Tests
Save fixed paths as tests. Prevent the same failure from shipping twice.
Framework Agnostic
Next.js, Express, Fastify, Hono, Koa, and Lambda. One SDK, any backend.
Install
One SDK. Any framework.
Start with one real endpoint: install the SDK, connect keys, expose the agent route, and wrap the backend path that fails most often.
Next.js Express Fastify Hono Koa Lambda
npm install fluxrunimport { withFluxNextJs, fluxHost } from 'fluxrun';
const db = fluxHost.auto('db', prisma);
export const POST = withFluxNextJs(
'orders.create',
async (flux) => {
const order = await flux.db.createOrder(flux.request.body);
return { status: 201, body: order };
},
{ host: { db } },
);
