Which Coding Agents tools are open source?

3 of the 19 we track have a public repository: MetaGPT (MIT), Aider (Apache-2.0), SWE-agent (MIT). Licence matters more than the label — check whether the licence covers the production server as well as the library.

What does a Coding Agents tool actually cost?

Published monthly prices run from $10 to $29, averaging about $17/month across 4 tools that publish a figure. 19 offer a free tier. The rest quote contact-sales or usage-based pricing, where the sticker price matters less than your usage volume.

Which Coding Agents tools are actively maintained?

Most recent commits among the open-source options: SWE-agent (2026-08-10), Aider (2026-05-22), MetaGPT (2026-01-21). A quiet repository isn't automatically a problem — a stable library needs fewer commits than a young one — but a year of silence is worth asking about.
