Interesting tools

Each week we review 2—3 of the most interesting developer tools. Here's what we featured this week.

Bubble Tea v2

Terminal UI framework.

What we like

Combined set of framework tools for TUI development: Bubble Tea (interactions), Lip Gloss (layouts), Bubbles (UI components). Uses a new rendering engine for performance. Improved support for inline images, clipboards, rendering sync. Declarative views.

What we don't like

Note that it’s Go-only. A good choice for terminal utilities though.

numpy-ts

NumPy implementation in TypeScript/JS.

What we like

Avoid splitting your stack if you’re already building in TS/JS. Tree-shakable library with universal runtime support across server and client. No additional dependencies. Validated against NumPy tests.

What we don't like

Not quite at 100% NumPY API coverage yet (94%). Slower than NumPy (average 11x slower, median 3x slower) for many of the benchmarks, as you’d expect.
