Carly and Devin are rated almost identically by users (4.4 vs 4.4), so the right pick comes down to feature fit rather than overall quality. Carly offers a free plan, making it the lower-risk option to try first — Devin starts at $500/mo. Carly tends to be favoured by freelancers and agencies, while Devin is more popular with programmers and enterprises.
Put Carly next to Devin and the differences surface fast — Carly is built around productivity tools while Devin leans toward coding tools. Carly is best known for always-on cloud agents, whereas Devin stands out for end-to-end task autonomy. Both land at 4.4/5 with users, so the right pick comes down to fit rather than raw quality.
Where Carly pulls clearly ahead is scheduling meetings based on calendar availability and preferences. A frequent plus in reviews: Truly autonomous, no prompting needed. Devin, by contrast, is the stronger choice for implementing a complete feature from a GitHub issue or specification. In its favour: Most autonomous coding agent available. Picking based on which of those jobs you actually do day to day beats chasing a longer feature list.
Carly addresses the real pain of calendar and email management with context-aware AI. Devin is genuinely impressive for well-scoped engineering tasks — the level of autonomous action is beyond what IDE plugins can achieve. If you only have budget or appetite for one, match the tool to your heaviest workflow rather than the spec sheet.
Choose Carly if you are focused on professionals and executives who want an AI assistant with deep calendar and email integration to manage scheduling, prioritise tasks, and reduce administrative overhead, or if a big part of your week goes to summarising emails and highlighting action items automatically. Its free tier also lets you validate the fit before paying.
Choose Devin if your priority is engineering teams wanting to offload well-defined, self-contained software tasks to an autonomous agent — particularly for implementing features from specifications, debugging issues, and modernising legacy code, especially for debugging a complex production issue autonomously by tracing through code. Note there is no free plan, so plan for a paid tier from day one.
In day-to-day use, Carly feels strongest at scheduling meetings based on calendar availability and preferences, while Devin is more at home with implementing a complete feature from a GitHub issue or specification.
Learning curve is worth weighing. Carly has a known trade-off — Newer product with fewer integrations — worth evaluating before committing if this is central to your use case. On Devin's side: Very expensive at $500/month — worth evaluating before committing if this is central to your use case. Whichever one slots into your current stack with the least friction tends to win in the long run.
Carly is the lower-risk start here: it has a genuine free plan, while Devin does not. Paid plans start at $20/mo for Carly (Pro) and $500/mo for Devin (Team), making Carly the cheaper entry point at $20/mo versus $500/mo. The extra spend on Devin only pays off if you need what its higher tier unlocks. The sticker price rarely tells the whole story — check seat counts and usage limits before you commit.
