Decision brief

GILD verdict

Choose Aider for engineers who steer edits file by file in the terminal on models they pick, with every edit committed to git.

Its last release shipped February 12, 2026, so your team supports whatever version it pins.

Fit and limits

Who it fits

  • Engineers work in the terminal and want a pair programmer that edits only the files they add, with a tree-sitter map of the whole repository sent alongside each request.
  • Model traffic must go to providers you choose. Aider connects to most LLMs: Anthropic, OpenAI, Gemini, DeepSeek, OpenRouter, Amazon Bedrock, Vertex AI, Ollama for local models, any OpenAI-compatible endpoint, and a GitHub Copilot token.
  • You want every AI edit in git. Aider first commits your own pending edits separately, then commits each of its changes with a generated message, and /undo reverts the last one.
  • Your team wants source it can audit and fork, under the Apache 2.0 license.

Where it falls short

  • Aider has no paid plan, support contract, SSO, admin console, or central policy, so each engineer's settings are the policy.
  • Releases have stalled. GitHub's latest release is v0.86.0 of August 9, 2025, and PyPI's is 0.86.2 of February 12, 2026.
  • The 54 commits on main through May 22, 2026, including settings for GPT-5.5 and Claude Opus 4.7, are in no release. GILD rechecked PyPI and GitHub on October 25, 2026 and found nothing newer.
  • It does less between prompts than agentic tools. It has no built-in MCP client, and the developer adds each file Aider may edit.
  • AIMultiple's June 2026 test ran the current Aider release, Claude Code, and Cline one-shot on Claude Sonnet 4.6, with no human steering. On a helpdesk build, Aider passed 13.3% of backend checks; Claude Code and Cline each passed 60%.
  • Several defaults need a team decision: auto-commits are on, and commits skip pre-commit hooks. A .aider.conf.yml in a cloned repository loads automatically, and a random subset of users is asked to opt in to analytics.

Implementation reality

  1. Pin the version and the models

    Install a pinned aider-chat version with uv or pipx so every engineer runs the same release. Version 0.86.2 supports Python 3.10 to 3.12, and the installers set up Python 3.12. Set the main, editor, and weak models in a shared .aider.conf.yml. The polyglot leaderboard shows which models edit reliably inside Aider, and its newest result is dated October 3, 2025, so test current models on your own repository.

  2. Enforce your git hooks

    Pre-commit hooks do not run by default, because Aider's commits pass --no-verify unless --git-commit-verify is set. Set git-commit-verify: true and keep auto-commits on so /undo can revert each edit. Squash Aider's commits before review if your team wants one commit per change.

  3. Treat repository config as code

    Aider loads .aider.conf.yml from the home directory, the git root, and the current directory, in that order. The file can set the lint and test commands Aider runs, so review it like any script in a repository you clone. Keep --yes-always, which confirms every prompt, to isolated automation.

  4. Check adoption and release pace

    On October 28, 2026 the repository showed 49.8k stars and 5.1k forks, and aider.chat reported 6.8M installs and 15B tokens a week. The history page lists unreleased main-branch changes. The community fork aider-ce, now published on PyPI as cecli-dev, shipped 1.10.0 on October 25, 2026.

What to measure in your pilot

  • GILD found no polyglot results for models released after October 2025 on Aider's leaderboard or in model launch posts. Run your candidate models on 20 of your own tasks before setting defaults.
  • AIMultiple tested only unattended one-shot builds; pilot Aider and your agentic tool on the same model with engineers steering, and log accepted changes and review minutes per task for four weeks.
  • Recheck PyPI and the GitHub commit log each quarter; if Aider still has no release after 0.86.2 at your next review, plan the move to a maintained tool.
