Aider VS Cline
Verdict BUY IT BUY IT
The Reality As of 2026-09-11, the GitHub repo has 48,897 stars, 4,945 forks, and 1,860 open issues, with a commit as recent as today — an actively maintained project, not an abandoned one. A "Show HN" post reached 432 points and 156 comments, one of the stronger developer-community receptions in this space. It's also a real, installable PyPI package (aider-chat, currently v0.86.2), not just a GitHub demo. As of 2026-09-11, the GitHub repo has 67,832 stars and 7,328 forks — the highest star count of any tool in this batch, despite the repo being created more recently (mid-2024) than Aider or Continue. Open issues (1,291) are proportionally in line with a project this size and this actively used. Its Hacker News posts scored more modestly (6 points and 2 points across two threads) than its GitHub numbers would suggest, which points to GitHub/word-of-mouth rather than HN as its main growth channel.
SHORT ANSWER
Aider: Aider is a free, open-source AI coding assistant that runs in your terminal and edits your local git repo via chat. With 48,897 GitHub stars and active daily commits as of September 2026, it's genuinely one of the most-used tools in this category, not just well-marketed.
Cline: Cline is a free, open-source autonomous AI coding agent for VS Code with 67,832 GitHub stars — the fastest-growing of the major open-source coding agents by star count relative to its age (launched mid-2024). Its Hacker News presence is modest, suggesting its growth comes mainly from elsewhere.
