blittermib. Pixelperfect MIB browser
Self-hosted — your MIBs never leave your server.

Privacy notice

blittermib is a self-hostable, server-rendered application with minimal data processing. This notice describes what the canonical public instance (operated by no42.org, see the imprint) does. If you self-host blittermib, the server-log section below applies to your deployment and you should adapt this page to match your own infrastructure.

Data handling

  • No cookies, no analytics, no tracking, no third-party embeds.
  • MIB files are read from the directory passed via -mibs on the server — they live on disk, are parsed locally by libsmi, and are never transmitted off the host.
  • Theme preference (light / dark) is stored in your browser's localStorage only. It never leaves the browser.

Web uploads

The canonical instance keeps web uploads disabled. Self-hosters who set BLITTERMIB_UPLOAD_ENABLED=true on their own deployment expose POST /api/v1/upload and DELETE /api/v1/upload/<name>: the uploader's IP appears in the standard access log subject to the same retention as below, and uploaded contents are stored verbatim under the operator's -mibs directory. Web uploads are an unauthenticated write surface — the operator's network is the only gate. The canonical instance does not enable them.

Server logs

The reverse proxy fronting the canonical instance retains standard access logs for 14 days containing:

  • IP address, timestamp, requested URL, HTTP method
  • Status code, response size, user agent and referrer headers

These serve operational purposes only (debugging, abuse mitigation) and are then automatically deleted.

Processing of the connection data above relies on Art. 6 (1) (f) GDPR — legitimate interest in the secure and reliable operation of the service.

Infrastructure

The canonical instance is hosted by IONOS SE in Germany. TLS encryption uses Let's Encrypt certificates.

Your rights

Under the GDPR you have the right to access, rectify, erase, restrict processing of, and port your personal data, and to lodge complaints with a supervisory authority. Contact details for exercising these rights are in the imprint.

No third parties

The site loads no external fonts, analytics scripts, or embedded widgets. The only outbound connections from your browser are the ones you explicitly click on.
