Reviews of the most interesting devtools and latest beta releases.
Here's the latest newsletter sent on 2026-08-27.
Each week we review 2—3 of the most interesting developer tools. Here's what we featured this week.
Durable streams on object storage.
Each stream is independent and scales with the object store, so disks or capacity to manage. Benchmarked up to 100 MiB/s per stream. Metadata control plane independent from storage (SQL, either an ordered command log in Postgres or SQLite). The client is HTTP. One binary (Rust).
Not designed for very low latency - object storage commit often requires tens of milliseconds.
CSS syntax highlighter.
Lightweight, zero-dependency library for syntax highlighting. Uses the CSS highlight API with no runtime dependencies. Clean DOM, no markup (uses pre and code blocks). Auto-detects language or you can force it with a class.
Has bundled themes, but it requires some work and custom CSS variables to create custom themes.
Here's the interesting beta and early access releases we featured this week.
Experimental AI code editor.
Fast, rootless sandbox.
Local-first AI agent workspace.
A program that is a SQLite database.
