Freebuff
Freebuff is the free coding agent: a free CLI coding agent and Freebuff Web, the free way to build full-stack apps. No subscription, no setup, no lock-in. The free alternative to Claude Code, Cursor, Codex, Lovable, Replit, Bolt, Windsurf, and Devin.
StackScope is a free public catalogue of indie launches. We find launches on Product Hunt, Hacker News and similar feeds, then crawl each site to detect its tech stack and score it for launch readiness: DNS, security headers, SEO basics. This page is what we saw on 18 June 2026; the live site may have changed since.
Freebuff looks production-ready overall, with complete legal pages, a thorough launch checklist, and clean crawl signals. Worth fixing first: missing several security headers, tracking cookies set before any opt-in, and no email security records.
Launched on Hacker News on June 17, 2026. The site is hosted on Render in the United States, with a domain registered in 2000. We've detected 12 technologies on this site, covering advertising, analytics, auth, and CDN. The stack includes Auth.js, Next.js, and React.
It's one of 93 launches on this exact stack.

Readiness Breakdown How?
Performance How?
Indicative grade from a single automated render, not a substitute for Lighthouse or field data, and not part of the StackScope score.
Vibe Score Breakdown How?
| Signal | Points |
|---|---|
| AI onboarding signals | +5 |
| AI writing signals | +5 |
| AI stack signals | +10 |
This score is based on structural patterns and is not definitive. Many legitimate sites may trigger signals, and AI-built sites may go undetected. It should be treated as an indicator, not a verdict.
