PyodideMozilla brings Python to the browser
5.0 (5 reviews)
Running full Python in the browser means users can create and run apps without any backend. It’s magical. Preswald uses Pyodide to support live preview, AI refactors, and stateful execution, all offline.
We considered Brython, Transcrypt, running a server and syncing via WebSockets.
Startup time and memory can be a pain. lazy-load what you can, and show a clear loading UI. Also: wrap filesystem access in a clean API. Pyodide's internal FS can be tricky.

MotherDuckThe ducking simple data warehouse for analytics
5.0 (3 reviews)
It brings the ergonomics of DuckDB to the cloud. We use DuckDB locally in Pyodide for browser-based apps, and MotherDuck lets users transition easily to larger, cloud-scale datasets without rewriting queries. Same SQL, better scalability.
If you’re already using DuckDB, integrating MotherDuck is almost zero effort and unlocks team sharing, auth, and query history. We also liked how easy it was to prototype with their Python SDK.

DuckDBrich, fast & open source.
5.0 (14 reviews)
It’s insanely fast for local analytical workloads, and integrates beautifully with Pandas. Perfect for CSVs and Parquet files in browser-based workflows. It also doesn’t need a server or setup which is a huge win for interactive demos.
DuckDB + Pyodide works surprisingly well. You can compile DuckDB to WebAssembly and run SQL queries in-browser with zero backend.
