Disposable webhook URLs for debugging integrations. Create a temporary URL, send traffic from any client, and watch requests arrive in real time with headers and body, no signup required.
- Instant endpoints with a TTL you choose (1, 6, or 24 hours).
- Live feed of incoming HTTP requests over SSE as they hit your URL.
- Inspect everything that matters: method, headers, body, content type, and timing.
- No accounts and no tracking. Data expires and is deleted on schedule.
Pick TTL, create your URL, and optionally self-host with the Deploy button.
Copy the hook URL, send a test request, and expand a row for headers and JSON.
The Blueprint in render.yaml provisions:
| Piece | Role |
|---|---|
| Web service | Runs the Next.js app (plan: standard in the sample file). |
| Render Postgres | Stores endpoints and request payloads (DATABASE_URL injected). |
| Cron | Hourly cleanup of expired data (plan: standard). |
Forks: point the deploy button at your repo by changing the repo= query on the button URL, or set NEXT_PUBLIC_BLUEPRINT_REPO_URL at build time so the in-app deploy link matches your GitHub remote.
- Push this repo to GitHub, GitLab, or Bitbucket.
- In the Render Dashboard: New → Blueprint → select the repo → deploy.
preDeployCommand runs scripts/migrate.js when DATABASE_URL is present so tables exist before traffic hits the new release.
| Variable | Required | Purpose |
|---|---|---|
DATABASE_URL |
Yes (on Render) | Injected from the linked Postgres service. |
RENDER_EXTERNAL_URL |
Auto on Render | Public base URL for full webhook links in the UI (docs). |
NEXT_PUBLIC_APP_URL |
No | Override the public origin if you use a custom domain and want that host in copied links. |
| Symptom | What to check |
|---|---|
| Database errors | TLS is configured for Render Postgres in lib/pgSsl.js. |
| Missing tables | Deploy logs should show Migrations applied. from preDeploy. |
| Wrong URL in the UI | Use the live service URL, or set NEXT_PUBLIC_APP_URL for a custom domain. |
| Layer | Choice |
|---|---|
| Framework | Next.js 14 (App Router), TypeScript |
| UI | Tailwind CSS v4, Render DDS components |
| Data | PostgreSQL via pg, raw SQL |
| Realtime | Server-Sent Events (SSE) for the request feed |
| IDs | nanoid for endpoint identifiers |
- Each endpoint accepts up to 100 stored requests; TTL options are 1 / 6 / 24 hours.
- Expired rows are removed by the cron job.
- No accounts, no cookies, no tracking. Protection is URL secrecy only.
