AI tools for developers: 27 tools by task

From autocomplete in your editor to tools that build a whole app from a prompt, these are the coding tools in our directory, plus the agent, automation and data tools developers often reach for. Compare the options for one task side by side.

Listed by task, alphabetical within each task, not ranked and not tested: we have not used these tools. Descriptions and starting prices are the ones on each tool's page, from the vendors' own sites and other public sources, and they change, so confirm on the vendor's site before you pay.

Before you pick a tool

Check where your code goes. Coding tools send your files or prompts to a vendor. Read the data and privacy terms, and your employer's policy, before you use one on private code.
Look at usage limits and how overage is billed. Many plans meter requests, credits or premium models, and the limits can change. The profile lists what we read on each vendor's pages.
Review what the tool writes. Generated code can contain mistakes and security problems. Keep tests and code review in your process whatever tool you use.
