Coding assistants are the most measurably useful AI tools in production — and the category where the licence and data-boundary questions are most concrete.
12 tools · 11 free or freemium · 0 with a published free allowance · updated 2026-09-18
Software & Dev — 12 AI tools reviewed on AI Supermarket, including GitHub Copilot, Cursor, Windsurf, Replit. 11 of 12 have a free or freemium tier. Every entry links to the vendor's official site. Machine-readable index: /llms.txt.
The category split is between completion and agency. GitHub Copilot, Tabnine and JetBrains AI complete what you are typing. Cursor, Windsurf, Bolt.new and Lovable operate at a higher level: you describe a feature and they edit multiple files, run commands and iterate.
The agentic tools have changed what a single developer can ship, particularly for greenfield work. They are also where the risk concentrates — an agent that can write files and run commands can make a confident, plausible mistake across an entire codebase.
The third axis is where your code goes. Tabnine emphasises private, trainable deployment. Amazon Q Developer and JetBrains AI keep work inside their respective ecosystems. For regulated teams, whether inference happens against a hosted service or a self-managed model is the deciding question.

For boilerplate, tests, unfamiliar APIs and greenfield prototypes, clearly yes. For work inside a large legacy codebase with implicit conventions, gains are smaller and depend heavily on how much context the tool can see.
Only with the same controls you would apply to any untrusted contributor: isolated environment, branch-based workflow, and review before merge. Agents make mistakes confidently, at volume.
That depends entirely on the tool and plan. Several vendors offer business tiers that exclude your code from training; check the specific terms rather than assuming.
