Best for	Teams with GitHub already. Devs who don't want to change IDEs.	Developers who want Cursor-like power for less money.	Developers. Non-developers who want to ship working code.	Vietnamese/Chinese content, SEA multilingual use, developers wanting open-weight tool-use.
Strengths	Great enterprise story Works in your existing IDE Chat + autocomplete	Cheaper than Cursor Cascade agent for multi-file tasks Solid free tier	Tab completion feels like mind-reading Composer for multi-file edits Runs Claude, GPT, Gemini — you pick	Excellent Chinese + Vietnamese + SEA languages Strong at tool-use + agentic workflows Open weights (Qwen2.5, Qwen3)
Weaknesses	Less agentic than Cursor/Claude Code Model quality varies	Smaller community Model selection more limited	Can feel overwhelming for non-coders Expensive at scale	English quality behind Claude/GPT Less well-known outside Asia
Kai's verdict	B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.	A-tier. Close second to Cursor. If $5/mo matters, start here.	S-tier for coding. If you write code of any kind, this pays back the $20 in a day.	A-tier. The best open model for Vietnamese + Chinese. Don't sleep on it if you work in SEA.
