Both are autonomous AI software engineers: you describe the task, they read the codebase, write the code, and deliver it to GitHub. The differences are how the work is priced, how it lands in your repo, and what checks run before it gets there.
Devin meters work in Agent Compute Units. The $20/month Core plan bills $2.25 per ACU on top of the subscription, and an ACU covers roughly 15 minutes of active agent work — third-party estimates put moderate Core usage at about $70–220 per month all-in. The $500/month Team plan includes 250 ACUs, then $2.00 per additional ACU. AUREM CTO is a flat fee: Free is 10 tasks/month, Starter is $9 for 50 tasks, Pro is $19 with unlimited tasks, Team is $49 per user. Ship 5 tasks or 500 — the invoice doesn't move.

25+ patterns checked on every change: AWS / GitHub / Stripe / OpenAI keys, DB connection strings, private keys, plus eval, shell=True, SQL string formatting and unsafe innerHTML. Critical hits block the commit.
DeepSeek V3 writes, Claude Sonnet reviews — wrong imports, logic errors and security gaps get caught before commit. 100 reviews/mo on Pro, unlimited on Team.
Direct commit via the GitHub REST API when speed matters, or a Pull Request when your team wants eyes on the diff.
Per-repo permanent memory: your stack, your conventions, your past decisions. Say "we don't use Redux" once.
Full web UI that works on mobile, plus a VS Code extension. No desktop IDE required.
Yes, if you want predictable cost and shipped commits. AUREM CTO is an autonomous AI engineer with flat pricing ($0 free tier, $9 Starter, $19 Pro unlimited tasks, $49 Team) instead of Devin's $20/month plus $2.25 per Agent Compute Unit metering. AUREM also runs a 25+ pattern security scan and an optional second-model code review (Maxx mode) before anything reaches your repository.
Devin bills by Agent Compute Units: the $20/month Core plan charges $2.25 per ACU on top, and the $500/month Team plan includes 250 ACUs. Moderate Core usage typically lands around $70–220/month in total. AUREM CTO is a flat fee: Pro is $19/month with unlimited tasks — 5 tasks or 500, the price is the same.
AUREM CTO supports two delivery modes: direct commit to your branch via the GitHub REST API for solo speed, or a Pull Request flow when your team prefers review. Devin delivers its work as pull requests.
AUREM CTO runs the Vanguard scanner on every change before it reaches GitHub: 25+ patterns covering leaked secrets (AWS, GitHub, Stripe, OpenAI keys, DB connection strings) and dangerous code (eval, shell=True, SQL string formatting, unsafe innerHTML), plus Python AST and esbuild syntax validation. On Pro and Team, Maxx mode adds a second-model review by Claude Sonnet before commit. Devin does not advertise an equivalent pre-commit security gate.
Devin is a strong fit for long-running, fully cloud-hosted sessions in its own VM, organisations that want VPC deployment, and teams already standardised on PR-only review with ACU budgets. If those matter more to you than flat pricing, a free tier, mobile access, or pre-commit security scanning, choose Devin.
