Team agent platform (Cosmos)

What it is
Built on a Context Engine that parses a repo structurally rather than treating code as flat text, which made it unusually strong on very large legacy codebases. During 2026 the company retired completions and moved off IDE extensions to Cosmos, a standalone SDLC platform wired into GitHub, Jira, Slack and CI.
Why it earns a slot
Still the strongest option for million-line monorepos where retrieval quality decides whether the agent is useful at all. A flat $100 a month for up to 50 seats is rare value, since you pay for usage rather than headcount.
Know before you commit
No free tier and no individual plan any more; new customers must adopt Cosmos, and the legacy IDE extension survives only for existing enterprise contracts. Poor fit below roughly five developers.
