Agent tools / Coding

Aider

Open source AI pair programmer for the terminal that edits files in your git repo with cloud or local models.

Supervision needed
Medium It commits each change to git so you can review and undo it, but you still need to read the diffs before you ship.
Where it tends to fail
Large repos where it edits the wrong files unless you add the right ones to the chat, and model bills that grow on long sessions.
Pricing
Free and open source under the Apache 2.0 license. You pay for the AI model you connect, or run a local model. Pricing page (Checked Oct 27, 2026)
