Comparison
Inlet vs Basin
Basin is a polished hosted form endpoint for static sites, with solid spam filtering and integrations. Inlet solves the same job — forms without a backend — but self-hosted, multi-tenant, and white-label, with an MCP server for AI agents.
Fair note: Basin is great for one team that wants a refined hosted endpoint with good spam filtering and Zapier-style integrations.
| Capability | Inlet | Basin |
|---|---|---|
| No SMTP or email library in your site | ||
| Self-hosted — you own the submission data | ||
| One backend serving many client sites | Per-account | |
| White-label auto-reply (client's brand, not ours) | ||
| Proof-of-work + NLP + reverse-DNS anti-spam | Spam filtering | |
| MCP server — AI agents create & read your forms | ||
| Runs on your own Supabase + Vercel (free tiers) |
The verdict
For a single team, Basin is a clean choice. If you run many client sites and want one dashboard you own, per-client branding, and AI agents that can wire and read your forms, Inlet is built for that.
