Cline vs Trae (2026)
Updated April 29, 2026
Overview
Cline is the OG open-source autonomous coding agent for VS Code with 5M+ installs. It creates and edits files, runs terminal commands, controls the browser, and supports MCP — all step-by-step with your permission. Free OSS extension; pay only for AI inference. Teams plan: $20/user/mo (first 10 seats free).
Trae is an AI coding platform with TraeCode, an AI IDE with unlimited autocomplete and SOLO mode, and TraeWork for running cloud tasks on web and desktop.
Key features
Core capabilities each platform advertises.
- Step-by-step permission gating for every file edit, command, and browser action
- Model Context Protocol (MCP) support for agent-extensible tools
- Works with any LLM — Claude, OpenAI, Google, local
- Browser control and full terminal integration
- Most-installed open-source coding agent on VS Code (5M+)
- TraeCode AI IDE with unlimited autocomplete
- SOLO mode included on every plan
- TraeWork cloud tasks on web and desktop
- Up to 20 concurrent cloud tasks on Ultra
Strengths and tradeoffs
What each tool does well, and the limitations to keep in mind.
Pros
- OG agentic coding agent — battle-tested with 5M+ installs
- Step-by-step permissions keep humans in the loop
- Pairs especially well with Claude Sonnet's tool use
- Open-source under MIT — no lock-in
- Strong community + active fork ecosystem (Kilo, Roo)
Cons
- VS Code only (JetBrains arrives with Teams plan)
- Pay-per-token costs add up for heavy agentic workloads
- Newer forks (Kilo, Roo) ship features faster
- Permission prompting can feel slow on long tasks
Pros
- Paid plans start at $3 a month
- Unlimited autocomplete on every plan
- SOLO mode included at every tier
- Concurrent cloud tasks scale from 2 to 20 by plan
Cons
- Usage is sold as dollar amounts, so it's hard to tell how many tasks a plan covers
- Trae's site doesn't name the models behind each plan
- Enterprise plans go through BytePlus rather than Trae directly
What people are saying
It's like having a senior dev who actually reads and understands your entire codebase before making suggestions.
