18 Best Glue Alternatives & Competitors (2026)
The top alternatives to Glue in the No-Code AI Builders space, compared on features, pricing, and what they're best at.
Updated March 27, 2026
Why look beyond Glue?
Glue is an open-source design editor that gives AI coding agents an infinite canvas to create and iterate on UI components, then export production-ready code in real time. Part of YC W2026, it was founded by Perbhat Kumar (ex-Amazon Kindle, ex-Microsoft Copilot Studio) and Tejas Priyadarshi (ex-Microsoft, ex-Meta).
Common reasons users explore alternatives
- Very limited framework support — currently only Next.js 14+ and Vite 5+ React projects
- Only Claude Code handoff works today — Codex and Gemini support coming soon
- Extremely early stage with 2-person team and unclear monetization path
- Annotation-based workflow may not scale for large redesigns requiring many UI changes
