LeapRows was born out of two frustrations: the "Python sharing problem" and server costs.
As an in-house SEO specialist, I frequently work with large CSVs exported from tools like Ahrefs, Google Search Console, and BigQuery โ often hundreds of thousands of rows. For heavy lifting, I'd reach for Python (Polars), but Python has a steep barrier: environment setup, code adjustments, and a learning curve that made it impossible to share with non-engineer teammates.
Even for myself, I'd often think "do I really need to write Python just for this small transformation?" On top of that, frustrating edge cases โ like type inference inconsistencies causing join errors on the same CSV from the same tool โ kept piling up.
I wanted something as easy as a spreadsheet but capable of handling millions of rows. That's what LeapRows is.

Opus, zero nudges. Realised on its own that an abandoned signup never fires identify, triangulated the anonymous session from time, platform and registration events, decoded the PostHog replay blobs, confirmed the duplicate account in Supabase, proved the reset email never sent, and pulled the root cause out of an unmasked DOM field. One prompt in; root cause out. - Source: dev.to / 25 days ago
Supabase is an open-source backend platform built around managed PostgreSQL. You get a database, auto-generated REST APIs (via PostgREST), Auth, file Storage, Realtime subscriptions, and Edge Functions - with a dashboard and SQL editor on top. - Source: dev.to / 2 months ago
If youโre starting fresh, go to Supabase and create a new project. Once your project is ready, copy the project URL and publishable (anon) key from the project settings. - Source: dev.to / 2 months ago
So I had to discover that and fix that, and start leaning on our database (Supabase is what Lovable uses by default). - Source: dev.to / 2 months ago
Verdict: start with Supabase on day one. Free tier carries you through launch. Upgrade to Pro when you legitimately outgrow it. - Source: dev.to / 2 months ago
