Devin by Cognition charges based on ACUs (Agent Compute Units), not seats or tokens. The Starter plan costs $500/month for 250 ACUs; the Teams plan is $1,500/month for 750 ACUs. Additional ACUs are available as pay-as-you-go top-ups at $2/ACU. When you exhaust your ACU balance, Devin pauses new tasks until you purchase more or your billing cycle renews.
- Starter: $500/month, 250 ACUs included
- Teams: $1,500/month, 750 ACUs included
- Pay-as-you-go top-ups: ~$2 per ACU
What is an ACU?
An ACU (Agent Compute Unit) is Devin's internal unit of compute consumption. One ACU represents roughly the compute Devin uses when executing a moderate-complexity task: reading a codebase, writing code, running tests, and iterating on failures. Simpler tasks consume fewer ACUs; long multi-step autonomous runs consume more. According to Cognition's documentation, typical tasks range from 0.5 to 5 ACUs depending on scope and the number of agentic steps involved.
ACUs are not equivalent to API tokens or model calls. They bundle together LLM inference, tool use, shell execution, and browser automation into a single metered unit. This makes costs more predictable for engineering teams, but also harder to optimize at a granular level compared to raw token pricing.
How do Devin's plans compare?
As of August 2026, Devin offers two primary subscription tiers plus enterprise pricing. The main difference is included ACU volume, team collaboration features, and access to priority compute queues.
| Plan | Monthly Price | Included ACUs | Additional ACUs | Best For |
|---|---|---|---|---|
| Starter | $500/month | 250 ACUs | ~$2/ACU | Solo developers, early pilots |
| Teams | $1,500/month | 750 ACUs | ~$2/ACU | Small engineering teams (3-10 devs) |
| Enterprise | Custom | Custom | Negotiated | Large orgs, compliance needs |
The Teams plan includes shared ACU pooling across team members, meaning one person can run a heavy autonomous sprint without others being blocked. Enterprise plans add SSO, audit logs, and dedicated compute capacity.
What are Devin's rate limits?
Devin enforces two types of limits: concurrent task limits and ACU balance limits. On the Starter plan, you can run up to 1-2 concurrent Devin sessions. Teams plans allow more parallel sessions. When your ACU balance hits zero, all new task submissions are blocked until you top up or your monthly cycle renews.
Unlike token-based tools that reset hourly or daily, Devin's limits are tied to your billing cycle. Your ACU balance renews on your monthly billing date, not on a rolling 24-hour or 7-day window. This means heavy usage early in a month can leave you rate-limited for weeks.
Concurrent session limits by plan
- Starter: 1-2 concurrent sessions
- Teams: Up to 5 concurrent sessions (shared pool)
- Enterprise: Custom, with dedicated capacity available
What happens when you hit the rate limit?
When your ACU balance is exhausted, Devin will refuse new task submissions and display an error in the dashboard. Any in-progress tasks at the time of exhaustion will typically complete (since compute is already allocated), but new tasks cannot start until the balance is replenished. You will see a notification prompting you to purchase additional ACUs or wait for your billing renewal.
If you hit concurrent session limits (rather than ACU exhaustion), Devin queues your request and starts it once an active session completes. Unlike the ACU limit, this does not require any top-up; it resolves automatically as tasks finish. For more on handling rate limit errors in agentic tools, see our post on Devin rate limit exceeded errors.
How do you monitor Devin usage?
Devin provides a usage dashboard in your account settings where you can see ACU consumption per task, current balance, and historical spend. Each completed or in-progress task shows its ACU cost, which helps you identify which types of tasks are most expensive.
Tips for managing Devin ACU consumption:
- Break large features into smaller, scoped tasks rather than single open-ended prompts
- Review ACU cost estimates before approving long autonomous runs
- Set budget alerts in your billing settings if available on your plan
- Use Devin for integration, testing, and boilerplate generation; use cheaper tools for quick edits
How does Devin's pricing compare to alternatives?
Devin is the most expensive AI coding tool in the market on a per-month basis. However, the comparison is not apples-to-apples: Devin runs fully autonomously for extended periods, while tools like Cursor or Claude Code require active developer supervision. The right comparison is output per dollar, not seats per dollar.
| Tool | Starting Price | Unit of Usage | Autonomy Level |
|---|---|---|---|
| Devin | $500/month | ACUs | Fully autonomous |
| Cursor Pro | $20/month | Fast requests | Copilot/agent hybrid |
| Claude Code (Max plan) | $100/month | 5-hour usage windows | Supervised agent |
| OpenAI Codex | Usage-based | Tokens | Agent (cloud) |
| GitHub Copilot | $10/month | Completions/requests | Inline suggestions |

Does Devin have a free tier?
As of August 2026, Devin does not offer a permanent free tier. Cognition has offered limited-time trial access and invite-based demos, but there is no ongoing free plan. The minimum paid entry point is the $500/month Starter plan. Some enterprise evaluations include trial ACU allocations negotiated directly with Cognition's sales team.
When does Devin usage reset?
Devin ACU balances reset on your monthly billing renewal date, not on a rolling daily or weekly window. If you subscribe on the 10th of the month, your balance resets on the 10th each month. There is no mid-cycle reset mechanism; if you exhaust your balance before renewal, you must purchase top-up ACUs to continue. For contrast, see how Codex usage resets, which operates differently.
Can you buy more ACUs before the cycle renews?
Yes. Devin allows on-demand ACU top-ups at approximately $2 per ACU. These purchased ACUs are consumed first before your monthly allocation in the next cycle, or they may expire based on your plan terms. Check your billing settings for top-up expiry rules specific to your plan.
Key takeaways
- Devin charges per ACU (Agent Compute Unit), not per seat or token.
- Starter plan: $500/month for 250 ACUs. Teams: $1,500/month for 750 ACUs.
- Additional ACUs cost approximately $2 each as pay-as-you-go top-ups.
- Rate limits come in two forms: ACU exhaustion (blocks new tasks) and concurrent session caps (queues tasks).
- ACU balances reset monthly on your billing date, not daily or weekly.
- No permanent free tier exists as of August 2026.
- For teams already using Claude Code, track and compare your spend using Usagebar's usage monitoring.
