Your client describes it. The PR writes itself.
Feedback automation for agencies and freelancers.
One script tag on a client site. Their request becomes a pull request in your repo.

The product lives at www.feedback2code.dev.
That is the hosted version: GitHub login, dashboard, widget, billing, and the agent that turns feedback into PRs. Free tier, no credit card, under three minutes to first setup.

This repository is the source of that product — published so you can see how it works. It is not a self-host kit and not open source. If you want feedback2code, use the cloud.
You ship sites for clients. They email screenshots, Slack you “can the button be blue?”, and you spend the afternoon translating that into a commit.
feedback2code puts a small chat widget on the live site. The client describes the change in their own words. An isolated coding agent clones the repo, implements it, and opens a pull request. You review the diff like any other PR.
Works on public and private GitHub repos. The widget is one script tag — no framework, no build step on the client site.
- Embed. Drop the snippet on any client site.
- Sandbox. Feedback schedules an E2B VM (2 vCPU, 2 GiB) that clones the target repo. The sandbox has no public internet.
- Agent. OpenCode with MiniMax-M3 implements the request inside the VM.
- PR. Your GitHub App bot pushes a branch and opens a pull request. You review, merge, or close.
GitHub credentials never stay in the agent’s environment: the sandbox mints
short-lived installation tokens, then scrubs the remote before OpenCode runs.
See lib/feedback-agent/e2b/e2b-github.mjs.
Freelancers and agencies who maintain client sites on GitHub and would rather review a diff than decode an email. It also fits SaaS products, docs sites, and internal tools — anywhere “change this on the live site” should become a PR.
The agent does not push to production. A bad change is a closed pull request.

Reading the source — env layout, GitHub App URLs, E2B template, Stripe
Local files: copy .env.example to gitignored
.env.development / .env.production. Do not commit secrets. Do not add
.env or .env.local — Next would load them and override the others.
GitHub App URLs use the same origin as NEXT_PUBLIC_APP_URL:
| Setting | Value |
|---|---|
| Setup URL | {origin}/api/github/setup |
| Callback | {origin}/api/github/callback |
| Webhook (optional) | {origin}/api/github/webhook |
Sandbox image: e2b/feedback-agent/e2b.Dockerfile
(feedback2code-agent, Node 20, OpenCode preinstalled). Production hosts need
E2B_API_KEY and optionally E2B_FEEDBACK_SANDBOX_TEMPLATE.
Stripe webhook: POST /api/stripe/webhook on the cloud origin
https://www.feedback2code.dev/api/stripe/webhook. Events:
checkout.session.completed, customer.subscription.created,
customer.subscription.updated, customer.subscription.deleted.
If a GitHub App push returns 403 / Permission denied to …[bot], set
Contents and Pull requests to Read and write, then reinstall the app
on the repos you use.
next/server after() still counts against the function max duration. A full
agent run can take minutes; production uses a host (or queue) that can wait.
