Riff (formerly Databutton)
Business/internal app builder
Free tier + paidAI app buildersriff.ai
What it is
Generates React frontends on a Python FastAPI backend, aimed at data-heavy internal tools with native connections to HubSpot, Google Sheets, Stripe, Notion and Mixpanel. The agent shows a task plan before it spends anything. Renamed from Databutton after a $16M Series A led by Northzone.
Why it earns a slot
The only mainstream builder with a real Python backend, so pandas work, scripts and data pipelines live inside the app rather than an external service. Aimed at analysts building operational tools, not consumer products.
Know before you commit
Renamed from Databutton in late 2025 and databutton.com now redirects, so older docs and links are unreliable. Support tiers jump from $20 to $700 a month with nothing in between.
