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. For teams with microservices or monorepo-adjacent architectures, this is a fundamental workflow difference.

Unlimited Parallel Agents

Agen has no cap on concurrent agents. Devin's Managed Devins support up to 10 parallel sessions. For teams that want to assign 20, 30, or 50 tasks at once, Agen scales without limits.

Scheduled Agents with Budget Controls

Both tools now offer scheduling. 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, which means runaway costs are possible on expensive recurring tasks.

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. You know exactly what you'll pay. Devin's per-ACU billing means costs scale with usage in ways that are hard to predict — a complex task that takes longer burns more ACUs, and you won't know the cost until it's done.

Where Devin wins

More Integrations

Devin already has Slack, Linear, and Jira integrations live. Agen currently supports GitHub and GitLab, with Slack and Linear coming soon. If your workflow depends on triggering agents from Slack or Linear today, Devin is ahead here.

Computer Use

Devin's Computer Use lets the agent control a full desktop environment — mouse, keyboard, browser. It can interact with any application, not just code. This is broader than Agen's preview system, which is focused specifically on previewing the running application.

Lower Entry Price

Devin's Core plan starts at $20/mo with pay-as-you-go pricing. Agen starts at $59/mo. For a single developer running occasional tasks, Devin's entry cost is lower — though per-ACU costs can add up quickly on heavier usage.

Mature Product

Devin has been in market longer and has more enterprise customers. For teams that need proven scale and established support, Devin's track record is longer.

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), making one task cost more than a third of Agen's monthly fee.
