3. Bun — The All-in-One JavaScript Runtime

Node.js had a good run. But in 2025, Bun is rapidly becoming the go-to runtime for JavaScript and TypeScript. It's faster, comes with a built-in bundler, test runner, and package manager — and it just works.

4. Replay.io — Time-Travel Debugging for Web Apps

Imagine recording a bug as it happens — then jumping back in time to replay the exact moment, step-by-step. Replay.io lets you do just that. It’s debugging made intelligent, visual, and asynchronous.

5. Raycast Extensions — Your Developer Swiss Army Knife

Raycast has gone beyond just being a Spotlight alternative. With extensions for GitHub, Jira, VS Code, Notion, and custom scripts, it’s now a command center for dev productivity.
