Genuinely writes, runs and tests code in its own sandboxed environment.
Beagle vs the rest
Beagle vs Devin.
Devin is an AI engineer that writes and ships code. Beagle is not, and does not pretend to be - it is the teammate for everything around the code: the customer thread, the CRM record, the weekly report, the chase. Plenty of teams run both.
Side by side.
Devin is an AI software engineer. Cognition's autonomous coding agent, working in its own cloud environment and reachable from Slack. Here is where the two part ways.
| Devin | Beagle | |
|---|---|---|
| Where it lives | A web IDE and CLI, plus Slack and Microsoft Teams. | Slack and Microsoft Teams, as a teammate. |
| Reads your channels | Channels you connect, including passive auto-triage. | Every channel it is invited to, scoped to what each teammate can see. |
| Takes initiative | Yes - auto-triage and scheduled automations. | Pipes up unprompted when something needs you. |
| Acts across your tools | Repos, trackers, and a real shell and browser. | Drafts and does the work across ~2,700 connected apps. |
| Learns your team | Persistent Knowledge, pinned per repo. | Remembers your tone, your people and what you decided. |
| Asks before acting | At pull-request review, not per action. | Always waits for your nod before anything goes out. |
| Pricing | Seats from $20/month, plus usage credits. | Free to start - 1,000 credits, no card. $49/mo adds 5,000 monthly. |
What Devin does well.
Nobody switches on a page that pretends the other tool is rubbish. Here is the honest case for Devin.
Auto-triage watches a channel and investigates bugs without being tagged.
Persistent Knowledge carries your repo conventions into every session.
Where Beagle fits.
The shape of work Devin was not built for.
Lives where you talk
Beagle is a teammate in Slack and Microsoft Teams, not a tab you switch to. It reads the channels it is invited to and answers in the thread.
Does the work, not just the talk
It drafts the reply, updates the record and chases the action item across ~2,700 tools - then waits for your nod before anything goes out.
Learns your team
Correct it once and it remembers. Over time it knows your tone, your accounts and your decisions - the part Devin leaves to you.
Which one should you pick?
They are built for different jobs. Pick by the job you actually have.
Pick Devin when the work you want handed off is engineering work: migrations, backlog tickets, bug triage inside a real codebase.
Pick Beagle when the work is everything else in your team's week, and it needs approving before it goes anywhere.
Common questions.
Is Beagle a good Devin alternative?
If you want an AI that lives in Slack and Microsoft Teams, reads your channels, and does the work rather than waiting to be asked, yes. Devin is an AI engineer that writes and ships code. Beagle is not, and does not pretend to be - it is the teammate for everything around the code: the customer thread, the CRM record, the weekly report, the chase. Plenty of teams run both.
What is the difference between Beagle and Devin?
Devin is an AI software engineer: Cognition's autonomous coding agent, working in its own cloud environment and reachable from Slack. Beagle is an AI teammate that sits in your Slack or Microsoft Teams channels, reads the thread, remembers your team, and drafts or does the work across roughly 2,700 connected apps - always pausing for your approval first.
When should I pick Devin over Beagle?
Pick Devin when the work you want handed off is engineering work: migrations, backlog tickets, bug triage inside a real codebase. Devin is genuinely strong at: Genuinely writes, runs and tests code in its own sandboxed environment. Auto-triage watches a channel and investigates bugs without being tagged. Persistent Knowledge carries your repo conventions into every session.
Can Beagle replace Devin?
It depends on the job. Pick Beagle when the work is everything else in your team's week, and it needs approving before it goes anywhere. Plenty of teams run both - Beagle covers the day-to-day work inside chat and hands off to the specialist tool where it is better.
Does Beagle work in Slack and Microsoft Teams?
Yes. Beagle lives natively in both, reading only what each teammate can see and waiting for your nod before it acts.
How is Beagle priced compared to Devin?
Beagle is free to start - 1,000 credits on signup, no credit card. A $49/month membership adds 5,000 credits every month, with one-time top-up packs when you need more. Devin prices seats from $20/month, plus usage credits.
