Reviews of the most interesting devtools and latest beta releases.
Here's the latest newsletter sent on 2026-04-16.
Each week we review 2—3 of the most interesting developer tools. Here's what we featured this week.
Outbound firewall.
Visualize (and block) outbound connections from any process or application. Tracks data volumes and history. Create your own blocklists and use community provided lists for proactive rule updates. Configurable. Open source. There’s also a macOS version.
Use of eBPF means it’s designed for privacy rather than completely strict security.
Fuzzy search library.
Supports fuzzy, token, and logical search with extension operators for exact, prefix, suffix, etc. Zero dependencies so it works in the browser, server (Node, Deno), etc. Search can be distributed across web workers for large datasets. Open source or use their cloud service.
Web workers are still in beta.
Here's the interesting beta and early access releases we featured this week.
Statically typed, web-native language.
Lightweight AWS emulator.
Subset of Go that compiles to C.
Agent-first database.
Stacked PRs support.
Python web framework.
