7 open-source alternatives to Retool
These tools replicate the core functionality of Retool without the SaaS subscription. Most are self-hostable; some also offer managed cloud editions.
Why switch? Self-hosting eliminates per-seat fees and keeps data on your infrastructure. Trade-offs: ops overhead, slower feature shipping, and you own backups. Pick a managed-cloud edition if you want fewer headaches.
