Pros & cons
- +Zero-install terminal workflow — agent where engineers already live
- +Open source under permissive license; auditable end-to-end
- +Ideal for one-shot refactors, audits, and migrations
- −No long-running session UI; not built for hour-long autonomous work
- −Less polished than IDE-native alternatives
- −You wire the model key + handle rate limits
- +Unique long-context model — can hold an entire mid-sized repo in one session
- +Strong on cross-cutting refactors that other agents struggle with
- +Funded at frontier-lab levels — engineering muscle behind the product
- −Enterprise pricing — no public per-seat tier
- −Newer entrant — fewer customer references than Devin or Cursor
- −Best for very large codebases; overkill for solo + small-team work
Pricing
- +Apache-2.0 binary
- +BYO OpenAI / Anthropic key
- +Composable from Makefiles + scripts
- +Long-context model (100M+ tokens)
- +Codebase-wide reasoning
- +Custom deployment
