aider installs as a single package. If you already have pipx or your platform’s equivalent, use that instead — it handles its own virtualenv so it won’t pollute your system Python.
Pull your existing key from Devin’s config and export it into aider’s environment. Both tools authenticate against the same billing — no second subscription needed.
Devin respects an implicit ruleset. aider reads its own config at repo root. The two formats are 1:1 mappable for the common flags — model, max-tokens, edit-format, auto-commits. Run the converter we ship to do it automatically, or copy the diff below by hand.
Run our verification suite against your real repo. We compare token usage + edit quality between Devin’s last response and aider’s first response on the same three prompts. If output diverges by >20% you’ll get a structured diff.
Direct link to the cancel-tier page (yes, they hide it three menus deep). Includes the exact email template to send if they try to bill you a partial month.
Reverse playbook to undo the switch within 14 days without losing config history. Restores billing and reverts your repo’s .gitignore so cache directories don’t end up in your tree.
