Framework-agnostic embeddable feedback SDK + self-hostable triage dashboard.
Docs · Self-host · SDK · Tester extension
Repro gives end users of any web app a one-click way to report bugs from the page — with an annotated screenshot, the last 30 seconds of session replay, and rich diagnostic context (console, network, cookies, system info) attached. Reports land in a self-hostable Nuxt dashboard where your team triages them, and optionally syncs them to GitHub Issues.
- Framework-agnostic SDK — drop-in widget for vanilla JS, React, Vue, Svelte, Angular, Nuxt, Next.js. No peer-dependency on the host's framework.
- Zero-config embed — single
<script>tag orimport { init } from "@reprojs/core". UI renders inside a Shadow DOM root so host styles can't leak in and vice-versa. - Rich context, collected automatically — every report bundles an annotated screenshot, rrweb-style DOM replay of the last 30s, console + network logs, cookies, and system info.
- Self-hostable end to end — SDK, dashboard, and Postgres all run locally via Docker. Blob storage is a pluggable adapter (local disk by default; S3-compatible for AWS S3, R2, B2, Hetzner, MinIO, etc.).
- GitHub-Issues sync — one-click "create issue" on a report, with two-way status sync via GitHub App webhooks.

Three first-class deliverables in one repo:
| Component | What it is | Who uses it |
|---|---|---|
SDK (packages/*) | Embeddable widget + framework-agnostic SDK | End users of whatever web app embeds Repro |
Dashboard (apps/dashboard) | Admin / triage UI + intake API | Your team |
Tester extension (apps/extension) | Chrome MV3 extension that injects the SDK into any page, with an intake proxy that bypasses strict CSPs | Internal QA on sites you don't control |
Note: packages are not yet published to npm. The examples below reflect the intended v0.1.0 install path.
<scriptsrc="https://your-dashboard.example.com/sdk/repro.iife.js" async></script><script>Repro.init({projectKey: "rp_pk_xxxxxxxxxxxxxxxxxxxxxxxx",endpoint: "https://your-dashboard.example.com",})</script>npm install @reprojs/coreimport{init}from"@reprojs/core"init({projectKey: "rp_pk_xxxxxxxxxxxxxxxxxxxxxxxx",endpoint: "https://your-dashboard.example.com",})import{identify}from"@reprojs/core"identify({userId: "user_123",email: "alex@example.com",name: "Alex Example",})Project keys are issued from the dashboard's project settings page. Each project has an origin allowlist — requests from any other origin are rejected and no CORS oracle is leaked.
Repro Tester is a Chrome MV3 extension for internal QA teams that need to file reports from sites they don't control (a staging build owned by another team, a vendor preview, etc.). It bundles the same @reprojs/core SDK, and its service worker proxies the intake POST so CSP-strict hosts don't block submission.
Install: grab repro-tester-vX.Y.Z.zip from the releases page, unzip somewhere stable, and load it via chrome://extensions → Load unpacked. Full guide: Tester extension docs.
The extension is not a replacement for the <script> embed — real users on customer sites always get the SDK via the embed. The extension is for internal testers only.
Prerequisites: Bun, Docker.
git clone https://github.com/Ripwords/ReproJs.git
cd repro
bun install
# 1. Copy env template
cp .env.example .env
# Edit .env — at minimum set BETTER_AUTH_SECRET and ATTACHMENT_URL_SECRET# (generate with `openssl rand -hex 32`)# 2. Start Postgres
bun run dev:docker
# 3. Push the schema
bun run db:push
# 4. Start the dashboard
bun run devDashboard is now at http://localhost:3000. Sign in with a magic link (prints to stdout when MAIL_PROVIDER=console), create a project, and you'll see a project key + embed snippets in Project → Settings.
For production deployment (Docker Compose with Caddy / Nginx reverse proxy, S3-compatible storage), see docs/self-hosting/.

| Concern | Choice |
|---|---|
| SDK runtime | TypeScript + Preact (tiny, React-like DX) inside Shadow DOM |
| SDK bundler | tsdown (ESM + IIFE) |
| Session replay | Hand-written rrweb-compatible event subset; dashboard replays via rrweb-player |
| Dashboard | Nuxt 4 (Vue 3 + Nitro server) |
| Database | PostgreSQL 17 + Drizzle ORM |
| Auth | better-auth with magic-link + GitHub / Google OAuth |

| Lint + format | oxlint + oxfmt |

One command releases everything affected by what's on main:
bun run release # patch every affected artifact
bun run release --minor # level applies to all affected
bun run release --dry-run # print the plan, change nothing
bun run release --only sdk # restrict (comma-separated); --skip is the inverseIt works out which artifacts are affected by asking what each one is built from — including the SDK bundle that the dashboard bakes into its image and the extension syncs at build time. So a packages/ui fix releases the SDK, dashboard and extension together, while a dashboard-only change releases just the dashboard. It shows the plan, asks once, then makes a single commit, tags each artifact, and pushes.
Version lines stay independent (sdk-v0.4.2 / v0.6.5 / extension-v0.1.4), so a dashboard change never forces a churn republish of @reprojs/core.
Mixed bump levels compose with --only:
bun run release --minor --only sdk
bun run release --only dashboard,extensionThe command runs lint, format:check, SDK build and SDK tests itself, and refuses to tag unless CI is already green on main. CI runs the full gate (including the dashboard integration tests against a real Postgres) on every PR and push to main.
Repro is pre-1.0 and under active development. v0.1.0 marks the initial cut of the rebranded monorepo with a working end-to-end flow: SDK → intake API → dashboard triage → (optional) GitHub Issues sync.
