Sentry DSN Parser & Builder

Parse Sentry DSNs into parts (public key, host, project ID), build the corresponding ingest URLs, and generate the X-Sentry-Auth header. Everything runs locally — no requests are made, keys never leave your browser.

Notes

DSN contains a public key — it's safe to embed in client code but still best practice to keep it out of public repos.
Secret keys (:secret) were deprecated in Sentry 9+ and are no longer used by modern SDKs.
The envelope endpoint is the modern ingest format that carries events, transactions, attachments, and sessions.
For self-hosted deployments, the host portion will be your Sentry domain (e.g. sentry.example.com).
