Cline vs Refact.ai (2026)

Cline

by Cline Bot Inc.

Refact.ai

by Refact

Pros

• ✓Fully open-source under Apache-2.0 with secure client-side architecture: all AI interactions go directly from the extension to the chosen LLM provider without Cline processing code in transit. The SDK released in May 2026 lets teams embed the Cline agent runtime into their own applications and tooling.
• ✓Provider flexibility across more than 40 documented providers including AWS Bedrock, GCP Vertex AI, Groq, Cerebras, Mistral, xAI and DeepSeek, plus local models through Ollama and LM Studio. Developers are never locked into a single AI vendor and can optimize cost and capability per task without switching tools or paying a separate subscription.
• ✓Five product surfaces (IDE extension, CLI, desktop app, Cloud Agents, SDK) cover different workflows: VS Code for interactive coding, CLI for headless CI/CD automation with messaging integrations (Slack, Telegram, Discord, WhatsApp, Linear), the desktop app and Cloud Agents for delegated sessions outside an editor, and SDK for embedding agents into custom products. Kanban orchestrates parallel agents across tools in a single UI.

Limitations

• –No commercial support or SLA on the open-source tier: community support relies on GitHub Issues and Discord, with no contracted response times unless organizations move to Enterprise at custom pricing. Teams with incident response requirements must engage Enterprise sales.
• –BYOK API cost management creates operational overhead: developers must monitor LLM API spending across providers, configure billing limits, and handle rate limit errors themselves. Fixed-subscription tools such as Cursor ($8/mo) or GitHub Copilot ($10/mo) bundle inference costs into a flat fee instead.
• –Compliance evidence is thin for regulated buyers as of Q4 2026: the trust center lists GDPR and SOC 2, but publishes no SOC 2 report of either type and carries no ISO 27001 or HIPAA. Enterprise offers VPC and air-gapped deployment for infrastructure control, which is not the same as third-party audit certification.
• –Cline states that it does not use your code to train models, but it routes prompts to third-party providers. Its privacy notice records that some of those providers may use content for training unless you opt out with that provider directly.

Pros

• ✓Free and open source under BSD-3-Clause, with users paying only the model providers they choose, including local runtimes such as Ollama, LM Studio and vLLM.
• ✓Runs entirely on the developer machine, sending requests only to configured providers and keeping project state in a local folder that can be inspected or deleted.
• ✓A task planner runs agents in isolated git worktrees, and the agent can use shell, browser, GitHub, GitLab, database, Docker and MCP integrations.

Limitations

• –No commercial support or SLA since Refact Cloud was retired, and development now rests largely on a single maintainer in a personal GitHub repository.
• –The resident background process and terminal interface are labelled an early preview, with the VS Code and JetBrains plugins described as the stable surfaces.
• –Users must install the local engine and configure their own provider keys or local models, and the refact.ai website still shows pre-shutdown messaging.
