Where Agen wins
Multi-Repo Sessions
This is the clearest differentiator. Real features span multiple repos. Agen handles frontend, backend, and infra changes in a single session with linked PRs and a cross-repository live preview. With Devin, you run separate sessions for each repo and coordinate the changes yourself.
Unlimited Parallel Agents
Agen has no cap on concurrent agents. Devin's Managed Devins support up to 10 parallel sessions.
Scheduled Agents with Budget Controls
Agen lets you set a maximum spend per scheduled run — the agent stops when it hits the budget limit. Devin's scheduling doesn't have this control.
Alerts
Agen agents can monitor your codebase and notify you when something needs attention — broken builds, security issues, performance regressions. Devin doesn't have an alert or monitoring system.
Flat, Predictable Pricing
Agen charges a flat monthly fee with included usage credits. Devin's per-ACU billing means costs scale with usage in ways that are hard to predict.
Where Devin wins
More Integrations
Devin already has Slack, Linear, and Jira integrations live. Agen currently supports GitHub and GitLab.
Computer Use
Devin's Computer Use lets the agent control a full desktop environment — mouse, keyboard, browser.
Lower Entry Price
Devin's Core plan starts at $20/mo with pay-as-you-go pricing.
Mature Product
Devin has been in market longer and has more enterprise customers.
Pricing comparison
| Agen Starter | Agen Pro | Agen Scale | Devin Core | Devin Teams | |
|---|---|---|---|---|---|
| Monthly price | $59 | $119 | $199 | $20 base | $500 base |
| Usage included | $20 credits | $40 credits | $80 credits | Pay-as-you-go | 250 ACUs |
| Overage cost | Standard rates | Standard rates | Standard rates | $2.25/ACU | $2.00/ACU |
| Parallel agents | Unlimited | Unlimited | Unlimited | Up to 10 | Up to 10 |
| Scheduled agents | — | ✓ | ✓ | ✓ | ✓ |
| Budget limits | — | ✓ | ✓ | ✗ | ✗ |
The math:
Agen's $59/mo flat rate includes $20 in credits. If you're running 5-10 agent sessions per week, Agen is predictably cheaper. Devin's $20 entry is cheaper for light usage, but a single complex task can burn 10+ ACUs ($22.50).
