You have developer resources and want JavaScript flexibility with a large open-source community. Appsmith's free cloud tier for 5 users is hard to beat for small teams wanting Retool-like power.
→ Choose Budibase if:
You want a no-code-friendly platform with a built-in database and workflow automation. Budibase is better for business analysts and operations teams who need to build tools without heavy coding.

Frequently Asked Questions
Editor's Take
I've built internal tools on both platforms. The honest split: if your team has even one JavaScript developer, go Appsmith — the flexibility is worth it. If you're a business team with no devs and need something this week, Budibase's built-in database gets you from zero to working app faster than anything else in this space.
