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.
Cline positions itself as an "autonomous coding agent" available as an SDK, IDE extension, or CLI assistant — able to plan and execute multi-step coding tasks, not just autocomplete.
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.
The star growth here is the fastest of the three tools in this batch relative to repo age, which is a genuinely strong signal — but it's worth noting the Hacker News numbers don't match that scale, so some of that growth is likely coming from within specific dev communities (e.g. VS Code extension marketplace, Reddit, Discord) that aren't reflected in this data yet. Worth revisiting once those sources are wired in.
Is Cline free?
Yes, Cline is open source and free. You connect your own AI model API key; costs depend on usage of that model.
How is Cline different from Aider or Continue?
Cline is positioned specifically as an autonomous multi-step agent (plans and executes tasks), rather than a chat-driven pair-programmer (Aider) or a fully customizable agent framework (Continue). All three are open source and actively maintained.
