Start coding without setting up a machine.
LESS SETUP. MORE MAKING.
Developer tools for the work between ideas.
Developer tools are most useful when they fit your existing language, repository, and working environment. This collection mixes complete workspaces with small utilities, making it easier to solve a particular bottleneck rather than migrate your whole stack.

BEFORE YOU PICK
A few useful questions
Is open source the same as free hosted service?
No. A source license and a hosted pricing plan answer different questions. An open-source tool may offer a free local edition and paid collaboration or management services.
Can I paste production secrets into any utility listed here?
Review the tool’s data handling first. Use non-sensitive examples when evaluating a formatter, API client, or online conversion service.
