Use the app: errorwolf.dev
Error Wolf is an open-source web app that compresses noisy console logs and stack traces before you send them to larger models.
The browser sends all OpenRouter requests directly to OpenRouter. Error Wolf does not proxy or store your OpenRouter key, input, or results. The server only checks whether a key exists for the hunt page.
The app sends anonymous crash reports when Error Wolf itself fails. Reports do not include user data, cookies, request data, or console output. The app removes key-shaped strings and limits error text before it sends a report.
The browser keeps up to 1,024 recent runs for 30 days. It stores this history in localStorage. The privacy page contains the full details.
Read the privacy page for the full policy.
Suggestions, product feedback, and bug reports are welcome. Please open a GitHub issue so we can track them in one place.
The app uses pnpm, TanStack Start, Cloudflare Workers, Vite 8, React 19, TypeScript, Tailwind CSS v4, and shadcn/ui. See AGENTS.md for project conventions and commands.
pnpm install
pnpm devTo run against the Workers runtime:
pnpm build
pnpm exec wrangler devAlchemy manages the existing error-wolf Worker. Same-repository pull requests
run an Alchemy plan after CI succeeds. Fork pull requests run CI only. A push
to master deploys production after CI succeeds.
The one-time stacks/github.ts stack creates an account-owned, least-privilege
Cloudflare plan token (read-only) and Alchemy state-store credentials for the
preview environment, and a separate deploy token for production. Run that
stack with the local bootstrap profile and
ALCHEMY_STATE_STORE_CREDENTIALS set. The bootstrap token is not used by
deployment workflows.
Set VITE_SITE_URL as a build variable in the Cloudflare project. Vite inlines
this value at build time.
SENTRY_AUTH_TOKEN is optional. Set it as a secret build variable to upload
source maps. The build succeeds without it.
