Reviews of the most interesting devtools and latest beta releases.
Here's the latest newsletter sent on 2026-02-05.
Each week we review 2—3 of the most interesting developer tools. Here's what we featured this week.
Find JS memory leaks.
Supports analysis of Chrome browsers, Electron, and NodeJS. Uses the Puppeteer API to automate memory analysis using browsers. Create files defining how to interact with pages. Can be used as an NPM package to run end to end tests. Includes a visual debugger.
Only supports Chromium-based browsers.
LAN discovery tool.
Scans your local network (mDNS and SSDP) to find devices, identifying them using ARP and manufacturer metadata lookup. Doesn’t require elevated privileges. Can also (optionally) scan ports. Built as a TUI, but can also run in the background with a queryable API. Supports themes.
Designed as a TUI so the CLI command is more limited.
