Both work in VS Code. Both are AI-first. Cline is a free extension that lives inside any VS Code install; Cursor is a fork of VS Code with AI baked in. The deeper integration costs more and locks you in. The looser integration gives you more freedom but a less polished experience. Here's where each one wins.
Free open-source VS Code extension with autonomous plan/act mode.
VS Code fork with AI integrated at every layer.
Cursor Tab is unmatched. Cline has none — you rely on VS Code's basic suggestions or Copilot if you have it.
Cline's plan/act split is the cleanest autonomous workflow in any VS Code surface. Cursor's agent mode is improving but Cline's is more deliberate.
Cursor $20/mo is predictable. Cline is API-metered — if you don't watch the bill, it adds up. (Mitigated by claudeapi.cheap.)
Cursor caps you. Cline through claudeapi.cheap can run 8 hours/day at $50-100/mo total — Cursor at that pace forces $200/mo Business plan.
Cline runs in any VS Code install. Cursor requires you switch to Cursor. If you have a VS Code setup you love, Cline preserves it.
Cursor's UI is more polished, AI features are baked into the editor at every level. Cline is a sidebar extension.
Cline if you want a free, open-source, BYOK-first agent that lives in any VS Code. Cursor if you value Tab autocomplete + polished UI and don't mind editor lock-in. Heavy users save the most money with Cline + claudeapi.cheap (no plan caps). Casual users may prefer Cursor's $20 simplicity.
claudeapi.cheap works with both: Cline accepts custom Anthropic base URLs in its settings; Cursor accepts custom Anthropic + OpenAI base URLs in its settings. Same sk-cc-... key powers both. 80% off direct API.
Get a free API keyYes — Cline is a VS Code extension and Cursor is a VS Code fork, so Cline installs and runs inside Cursor. You'd get Cline's plan/act mode + Cursor's Tab autocomplete in one editor. Common power-user setup.
Cline is a thin client over your API key. The Cline team makes no money from your usage — every token cost goes to your API provider (or to claudeapi.cheap, who passes 80% off). Cline's business model is mostly community + future enterprise tier.
Cursor's agent mode is similar but less explicit. Cline's plan/act split forces you to review the plan before changes happen. Cursor blends them more, which is faster but riskier.
Both tools save 70-80% off official API. For Cline: typical user goes from $150/mo direct to $30/mo through us. For Cursor BYOK: typical user goes from $20 Pro plan ($0 BYOK API) to $20 + $30 BYOK = $50 total — but with no fast-request cap. Heavy users save more.
