Cline vs Supermaven
Pricing
Cline: Free (open source), you pay for the AI API you choose
Supermaven: Being sunset since November 2025, free autocomplete for existing users
Description
Cline: Open-source VS Code extension that acts as an autonomous coding agent. Bring your own AI model
Supermaven: Fast AI code completion that Cursor acquired in 2024 and began shutting down in November 2025
Pros
- Use any AI model (Claude, GPT-4, Gemini, local models): you control the cost
- Can browse the web, run terminal commands, create files, and edit code autonomously
- Free and open source: no subscription, just API costs
- Existing JetBrains and Neovim customers keep free autocomplete
- Fast completions, with a 1 million token context window on the Pro plan
Cons
- API costs are on you and can surprise you if you are not watching
- Setup takes more work than commercial alternatives: API keys, model selection, configuration
- Quality depends entirely on which AI model you pick
- Agent chat was discontinued in November 2025
- VS Code users have been told to move to Cursor
- No new features: the product is being wound down
Details
Cline is a VS Code extension that turns your editor into an AI coding agent. Pick your AI model (Anthropic Claude, OpenAI, local models through Ollama), give it a task, and it will plan, write code, run commands, and iterate. It asks for permission before each action, so you stay in control.
The big advantage over Cursor is flexibility and transparency. You see exactly what you are paying (API costs per request), you can switch models anytime, and there is no subscription. The big disadvantage is that you have to manage all of that yourself. If you want something that just works out of the box, Cursor is easier. If you want to pick your own model and only pay for what you use, Cline is the way.
Supermaven was the speed king of AI code completion. Built by the creator of Tabnine, it focused on autocomplete with very low latency and a massive context window. Cursor acquired Supermaven in November 2024 and folded its technology into the Cursor editor.
On 21 November 2025 Supermaven announced its sunset. Agent conversations ended, paying customers received refunds for their remaining time, and VS Code users were told to move to Cursor. Existing JetBrains and Neovim customers keep free autocomplete for the foreseeable future. There is no reason to start with Supermaven today: Cursor carries its completion technology, GitHub Copilot works in VS Code and JetBrains, and Devin Desktop (formerly Windsurf) offers unlimited Tab completions on its free plan.
