15 Best Free Developer Tools That Actually Save Time
The Free Stack That Works
Every developer needs a set of free tools that just work. Here’s our battle-tested toolkit — no fluff, all production-ready.
1. Bitwarden — Password Manager
Free forever. Open source. Syncs across all devices.
2. WARP (Cloudflare) — VPN
Free VPN that doesn’t sell your data. Fast, minimal.
3. Insomnia — API Testing
Free, open source API client. Better than Postman for most use cases.
4. DBeaver — Database GUI
Free, open source database manager. Works with MySQL, PostgreSQL, everything.
5. TablePlus — Database GUI
Free for 2 databases. Beautiful, fast, native feel.
6. Warp Terminal — Better Terminal
AI-enabled terminal that’s actually pretty. $10/mo for pro, but free tier is solid.
7. httpie — API Testing from CLI
http GET api.example.com — simpler than curl for complex requests.
8. ShellCheck — Lint Your Shell Scripts
Find bugs in bash/shell scripts before they crash production.
9. Prettier — Code Formatter
opinionated, deterministic. Stop arguing about formatting.
10. ESLint — JavaScript Linter
Catches errors before they reach production.
11. GitHub CLI
gh — do everything GitHub without the browser.
12. http-server — Quick Local Server
npx http-server — instant static file server for testing.
13. Postman (Free Tier) — API Client
Good enough for most API testing needs. Free tier works for solo devs.
14. Browser DevTools — Already Installed
Chrome DevTools, Firefox DevTools. Both are incredibly powerful and free.
15. Stack Overflow — Search, Don’t Sign Up
The free knowledge base. When you Google a coding error, it’s Stack Overflow.
