The Best Developer Tools to Save Hours Every Week
Great developers aren't just good at writing code — they're ruthless about eliminating busywork. A well-chosen set of small utilities can quietly reclaim hours every week. Here are the categories worth keeping one tab away.
Key takeaways
- Formatters and validators catch mistakes before they cost time.
- Encoders and converters remove repetitive manual conversions.
- Testers for regex and JWTs turn guesswork into instant answers.
- Browser-based tools keep sensitive data off third-party servers.
Formatters and validators
JSON, XML, SQL and code formatters instantly turn messy input into clean, readable structure — and flag syntax errors while they're at it. Reaching for one whenever you inspect an API response or hand-edit a config file saves constant squinting and prevents avoidable bugs.
The time saving is small per use but enormous over a week, because these are things you do dozens of times a day.
Encoders and converters
Base64 encoders, URL encoders, timestamp converters and colour-format converters remove the friction of tasks you can't quite do in your head. Instead of context-switching to write a throwaway script, you paste, convert and move on.
Keeping these in a single workspace means you're never more than a click away from the transformation you need.
Testers and generators
Regex testers let you build and verify patterns against real input instead of deploying and praying. JWT decoders reveal exactly what's inside a token. Hash and QR generators, along with text-diff tools, handle the long tail of everyday tasks.
Favour tools that run entirely in your browser — when you're pasting tokens or internal data, you don't want it travelling to someone else's server.
