This Week's Finds
Jul 20–26, 2026
-
MIT-licensed Python linter and formatter written in Rust, from Astral and already a default across much of the ecosystem for its speed. The v0.16.0 release expands the defaults dramatically, with the recommended rule set jumping from 59 to 413 rules so a fresh install catches far more out of the box without extra configuration. Free and open source; Astral funds the work through its paid registry and the uv toolchain rather than the linter itself. 48.9k stars
-
MIT-licensed multimedia sketchpad by John Earnest that builds openly on the legacy of HyperCard and the classic Mac creativity tools. It bundles a paint program, hypertext linking and a small scripting language into one app for making and sharing interactive documents, decks and small toys that run anywhere, with no account or cloud involved. Free and open source. 1.6k stars
-
MIT-licensed presentation tool that fits an entire slide deck, editor and all, into a single HTML file of around 560KB. Open it in any browser to edit, present, print and save with no install and no login, and it keeps working fully offline, with the slide data stored as plain JSON near the top of the file. Live collaboration runs through an encrypted blind relay that never sees your content, and you can hand an existing PowerPoint to an AI assistant to convert it into a deck. Built on reveal.js by its creator, free. 2.4k stars
-
Free plain-text weather site for anywhere in the world, built by jsax as an at-a-glance alternative after the UK Met Office redesigned its site into something busier. It lays out a seven-day outlook, a previous-day comparison and hourly rain, wind, temperature, UV, air quality and pollen as dense character-based visualisations in one scrollable column that works well on a phone. Every view, down to the selected day and which sections are expanded, lives in the URL, so you can share or bookmark an exact forecast. Built in Go on PocketBase with weather data from Open-Meteo, with no accounts and no paid tier.
-
GPL-3.0 native macOS video editor from Palmier, built for an AI-assisted editing workflow and running locally on the Mac. The full source is open for you to build and run yourself. Free and open source. 12.5k stars
