If you’re searching for a Devin free plan in 2026, here’s the honest answer: there isn’t one. Unlike most AI coding tools, Devin starts at the $20 Core plan with pay-as-you-go usage on top. This guide breaks down exactly what each Devin tier gets you, how the ACU billing actually works, and when paying more is worth it.
Free vs Paid at a Glance
| ”Free” | Core ($20) | Team ($500/mo) | |
|---|---|---|---|
| Price | None — no free tier | $20 entry + ACU usage | $500/mo |
| Included ACUs | — | Pay-as-you-go | 250 ACUs |
| ACU rate | — | $2.25 each | $2.00 each |
| Concurrent sessions | — | Up to 10 | Unlimited |
| Best for | — | Trying Devin, small tasks | Daily autonomous work |
Is There a Free Devin Plan?
No. Devin (by Cognition) is positioned as an autonomous AI engineer, not a casual chatbot, so there’s no free tier and no perpetual trial. The lowest-cost way in is the $20 Core plan, which then bills usage per ACU. If you want to try autonomous coding for free first, look at tools with genuine free tiers in our best Devin alternatives guide.
What Core ($20) Gives You
Core is the entry point for individuals and small teams testing Devin on real work:
- Pay-as-you-go ACUs at $2.25 each — you fund usage as you go
- Up to 10 concurrent sessions
- Best for smaller features, bug fixes, and limited projects
An ACU (Agentic Computing Unit) ≈ 15 minutes of active autonomous work. So the $20 sticker is really an access fee — your true cost depends on how many ACUs your tasks consume. A quick bug fix might be a fraction of an ACU; a multi-file feature can be several.
What You Unlock With Team ($500/month)
Team is for developers running Devin daily as a real teammate:
- 250 ACUs included at the cheaper $2.00 rate
- Unlimited concurrent sessions (no 10-session cap)
- Early feature releases and research previews
- Optional onboarding call with the Cognition team
The unlimited sessions matter most — you can fan out many tasks in parallel, which is the whole point of an autonomous engineer. Compare this delegation model against an interactive IDE in our Devin vs Cursor breakdown.
The ACU Reality
| Usage profile | Likely monthly cost |
|---|---|
| Occasional small fixes | $20 + a few ACUs |
| Regular feature work | $100–300 (Core + ACUs) |
| Daily parallel tasks | $500 (Team, 250 ACUs) |
| Beyond 250 ACUs | $500 + $2.00/ACU overage |
Because cost scales with task complexity, budget for usage above the base price — the same usage-based shift happening across the category, including GitHub Copilot’s move to credits. Full numbers in our Devin pricing guide.

FAQ
Is Devin free? No — there’s no free plan. The cheapest entry is the $20 Core tier with pay-as-you-go ACU billing.
What does the $20 actually buy? Access to Core with up to 10 concurrent sessions; ACU usage is billed separately at $2.25 each.
How much is an ACU? $2.25 on Core, $2.00 on Team. One ACU is roughly 15 minutes of active autonomous work.
When is Team worth $500? Once you need unlimited parallel sessions or regularly use close to 250 ACUs a month — the lower $2.00 rate then pays off.
