Aider
Aider is an open-source AI programming assistant that runs primarily in command-line environments and supports deep integration with Git repositories. It allows users to write, modify, and refactor code through natural-language conversation. The tool is compatible with multiple mainstream large language models and maintains a coding benchmark leaderboard based on real code-editing tasks, used to evaluate the practical coding performance of different models.

Timeline (last 90 days)
The edit formats supported by Aider include whole, diff (SEARCH/REPLACE blocks), diff-fenced (mainly aimed at Gemini models), udiff (a simplified unified diff), and two editor- variants in architect mode.
Aider's diff format behaves similarly to Codex in repeated-line scenarios: perfect_replace in editblock_coder.py replaces the first matching block and then returns; only when a SEARCH block elides lines with ... and that fragment appears multiple times does Aider refuse.
Aider's whole format requires the model to return the entire file content and overwrite directly, with no risk of match failure, but it consumes many tokens and may overwrite concurrent changes.
Aider's udiff is a simplified unified diff that keeps the +/- line markers but omits line numbers and most metadata, aiming to reduce the model's tendency to elide code with comments.
Aider's diff-fenced is a variant of diff in which the difference is that the file path is written inside the code fence, and it is mainly aimed at Gemini models.
Aider's diff format uses SEARCH/REPLACE blocks: the model outputs a <<<<<<< SEARCH section (the original code to find) and a >>>>>>> REPLACE section (the replacement code), and the applier locates the SEARCH content in the file and replaces it wholesale with the REPLACE content, relying on no line numbers and not requiring the full file to be output.
Aider's polyglot leaderboard (last updated on November 20, 2025) lists a Correct edit format column next to the pass rate on 225 exercises, with gpt-5 (high) in first place at 88.0% correctness and a format correctness rate of 91.6% when using the diff format.
Aider also reads the ~/.aider.conf.yml configuration file.
Through the goroute setup all command, GoRoute can automatically configure terminal coding tools such as Claude Code, OpenCode, Codex, Cursor, Aider and Cline.
The five fastest-growing tools in the OWASP-tracked dataset (Claude Code, Gemini CLI, Codex, Cline, and Aider) all belong to the coding agent category.
