Show HN: Free Logo API – logos for any company or domain

The Clearbit Logo API finally went down yesterday after the HubSpot acquisition. I relied on it across several projects (heavily), so I built a drop-in replacement:

Key features:

- Free to use, no signup or API key needed

- Both companies and domain names work as input identifiers

- WebP format for smaller payloads and better cache hit rates

Stack: S3 for storage, heavily cached fastapi, Next.js for the site. Everything's behind Cloudflare for proper CDN/caching. This was the first time I tried to build something end-to-end from idea to deployment with Claude Code (Max) and I have to say, Opus 4.5 took it like a champ!

For the younger folks, here's what the old Clearbit API looked like: https://web.archive.org/web/20230920164055/https://clearbit....

Happy to answer questions about the implementation or hear your thoughts!
