Upgrade to Pro
Self-host

Run it on your own Cloudflare and Supabase.

The full HTMLRadar source is AGPL-3.0. The tracker, the proxy worker, the schema, the web app — all of it lives on GitHub. The free tiers on Cloudflare and Supabase cover personal use. The repo includes a 15-minute self-hosting guide.

Need to use HTMLRadar inside a closed-source product, or run a hosted service without AGPL's copyleft? A commercial license is available — email us.

  • Audit the data path. Recipients can see exactly what's being tracked. Closed-source competitors can't offer that.
  • No caps when self-hosted. Unlimited documents, unlimited attachments. Pay Cloudflare and Supabase directly, not us.
  • AGPL keeps it open. Anyone can fork — but improvements come back. The project can't be swallowed by a larger SaaS.
Roadmap

What we're building next.

Public-visible and trackable on GitHub. Nothing here is promised inside the Pro tier above — it moves into Pro the moment it's shipped, not before.

FAQ

Common questions.

Is there a free plan?
Yes. The hosted free tier covers 2 tracked links across any number of documents, with full section-level tracking — no credit card needed.
What does Pro add?
Unlimited tracked links, no "Powered by HTMLRadar" footer on recipient views, and priority support. $15/mo flat — not per seat.
Can I run HTMLRadar for free forever?
Yes — self-host it. The full source is AGPL-3.0 on GitHub and runs on your own Cloudflare and Supabase accounts; their free tiers cover personal use.
Do recipients need an account?
No. Recipients just open the link. If you enable the email gate or a password on a share, they verify before the document renders — still no account.
