Our take on Cline
Cline is the open-source coding agent that punches above its weight. Lives inside VS Code, brings your own LLM key, and gives you a level of transparency proprietary tools can't match.
- +Fully open source — audit every prompt, every tool call
- +Bring-your-own-model — works with Claude, GPT-4, Gemini, local models via Ollama
- +Inline diff UX in VS Code is the cleanest in the category
- +No per-task pricing — pay only your LLM provider
- −Setup is more involved than a one-click SaaS
- −No background / async mode — agent runs while VS Code is open
- −Quality is bounded by the model you choose; cheap models give cheap results
- −Documentation is improving but still lags polished commercial tools
- ·Engineers who want full control over the prompt and tool use
- ·Teams with corporate AI policies that disallow third-party SaaS
- ·Anyone already paying for Claude or GPT-4 API access
- ·You're responsible for the cost ceiling — runaway loops can burn $50 fast
- ·Self-hosted models work but give noticeably weaker results below 30B params
Architecture
Cline runs as a VS Code extension. It talks to your chosen LLM provider directly (no intermediate proxy), reads and writes files in your workspace, runs commands in the integrated terminal, and uses Playwright to drive a headless browser when needed.
Because there's no SaaS layer in between, every prompt, every tool result, and every edit is visible to you. This is a meaningful difference: when Cline misbehaves you can read the transcript and fix the prompt. With closed-source agents, you can't.
What you get for the open source price
Cline includes every major agent capability we look for:
- File edits with diff approval before each change
- Shell command execution with a confirm step you can disable per-command
- Browser automation for tasks like reading docs or filing GitHub issues
- Plan / Act mode toggle — sketch a multi-step plan first, then execute it
The only thing missing versus paid alternatives like Devin is background execution. Cline runs in your editor while you watch. Close VS Code, the agent stops.
Cost math
This is where Cline gets interesting. Using Claude Sonnet 4 for a typical 30-minute session — adding a feature, debugging, running tests — usually lands at $1-$3 of API spend. A heavy refactor across 20 files might hit $8. For most engineers, monthly cost sits between $20 and $80 — and you can hard-cap it via your provider's billing controls.
Compare to Cursor's $20/mo (capped requests) or Devin's $500/mo entry tier, and Cline ends up cheaper for moderate use, comparable for heavy use, and explicitly capped on the high end.
Where Cline really wins
Two scenarios where Cline is the right answer:
- You want to understand what the agent is doing. Cline's transparency is unmatched. You can debug the prompt itself.
- Corporate policy disallows agent SaaS. Self-hosted, your-keys-only, deployed via an enterprise VS Code marketplace — Cline ticks every compliance box that paid competitors can't.
Bottom line
Cline is the answer when you want a real agent without a vendor. Pair it with Claude Sonnet 4.7 and you get 85% of Devin's quality at 10-15% of the cost — but you give up background execution and pay in setup friction.

Questions fréquentes
Cline est-il vraiment gratuit ?+
L'extension Cline elle-même est gratuite sous Apache 2.0 — vous pouvez auditer le code source, le forker, le faire tourner air-gapped. Ce qui coûte, c'est l'API key LLM que vous apportez (Anthropic, OpenAI, Gemini ou local via Ollama). L'usage daily-driver typique est de 40-120 $/mois de coûts en tokens pour les modèles cloud — ou 0 $ si vous self-hostez sur du hardware existant.
Cline ou Cursor — quelle est la différence ?+
Cline est une extension VS Code open-source où vous apportez votre propre API key modèle ; Cursor est un éditeur closed-source poli à 20 $/mois forfaitaire. Cline gagne sur la transparence, la flexibilité de modèle et la conformité. Cursor gagne sur la finition, l'autocomplétion tab intégrée et les coûts prévisibles.
Cline fonctionne-t-il avec des LLM locaux ?+
Oui — Cline s'intègre avec Ollama, LM Studio, vLLM et tout endpoint compatible OpenAI. Llama 3.3 70B ou Qwen 2.5 72B, fait tourner localement, gèrent la plupart des tâches coding quotidiennes. Cela fait de Cline le choix pratique pour les environnements air-gapped ou réglementés.
