Reviews of the most interesting devtools and latest beta releases.
Here's the latest newsletter sent on 2026-04-02.
Each week we review 2—3 of the most interesting developer tools. Here's what we featured this week.
Streaming-first data visualization.
Push streaming data at 60fps or just pass an array of static data. Simple React library that gives you full access to the underlying components if the built-in ones aren’t sufficient. Supports a range of charts and frames. Customizable with themes. Also supports server-side rendering.
If you need basic charts with minimal customization then it’s overkill - they recommend something like Recharts in that case.
Runtime AI safety sandbox.
Snapshots filesystem changes so you can easily roll back. Uses Kernel-level isolations on macOS, Linux, and Windows. Immutable session logs with cryptographic verification. Native SDKs for Python, TypeScript, Rust.
You need to use C FFI bindings for other languages (great they exist of course, but better to have native SDKs where possible).
Here's the interesting beta and early access releases we featured this week.
Lightweight syntax highlighting.
Information discovery for agents.
Policy enforced shell for agents.
In-process reimplementation of PostgreSQL.
