Both products start from a task and end with a pull request. The difference is in who steers the agent, what you pay for, and what happens after the pull request opens.
Devin is an autonomous engineer. You give it a task and it goes away, works, and comes back with a pull request. The unit is a piece of work.
Talyn runs your own agents in parallel cloud sandboxes. Each task is a session with its own branch, agent, diff and terminal. You steer it from the chat, and Talyn takes it through to a merged pull request.
What Devin does
As of 10 November 2026, from its own pricing page:
- An autonomous coding agent that takes a task, works in its own environment, and produces a pull request.
- Devin Cloud, Devin Desktop, and free use of its SWE-2 model on Pro and above.
- Pricing: a Free tier with a light usage quota, Pro at $20/month, Max at $200/month, Teams at $80/month plus $40/month per developer seat up to 200 users, and custom Enterprise. Each paid plan carries a usage allowance that refreshes daily and weekly; beyond it you buy extra usage at API pricing.
The usage model is the thing to understand: allowances refresh, and past them you are paying per unit of work at API rates.
What Talyn does
- A session per task. Each session has its own branch, agent, sandbox, diff, terminal and run scripts. Run many at once, and they never touch each other's files.
- Threads for work across repositories. Give a thread a goal and it starts a session on every repository that needs a change, then keeps track of each.
- You stay in the loop. Send messages while the agent works, read the diff, start your app, or roll the files back to an earlier message.
- Past the pull request. One button opens it. The same button then fixes failing checks, resolves conflicts and merges.
- Pull requests you did not start in Talyn. A dashboard lists every pull request you own or need to review. Send an agent to fix one, and it pushes to the same branch.
- A merge queue that lands ready pull requests in order and sends an agent when one breaks.
- Code review in the app. Findings reach GitHub only if you post them.
- Work that starts without you. Scheduled automations run a prompt on a schedule. GitHub automations run on pull request events.
The billing difference
Devin sells you inference. The allowance refreshes, and past it you pay API rates for the work.
Talyn sells you the machines. Every session runs on the Claude Pro/Max or ChatGPT Plus/Pro subscription you already pay for. You sign in with Claude or ChatGPT. There is no API key and no token markup. Talyn is free with 10 box-hours a month, or $40/month for 200 box-hours.
Each session runs in its own Firecracker microVM on our hardware. A proxy outside the machine adds your credentials, so no token is inside the box that runs your code. A sandbox sleeps after 10 idle minutes, and a sleeping sandbox costs nothing.
That matters if you already pay for a coding agent subscription and watch it sit idle most of the day.
What Talyn does not do
- It is not built as an autonomous engineer. A session is your agent on your branch, and you steer it. If you want to assign a ticket and not look at it again, Devin is closer to that.
- Little shared memory. Sessions save short notes as they learn your codebase, and that is all.
- No IDE integration.
- No public mobile app yet.
- GitHub only.
What we did not find in Devin's docs
Devin's pricing page does not describe these (checked 10 November 2026). Devin may offer some of them elsewhere, so check before you rely on this list.
- Watching a pull request after it opens: red CI an hour later, a branch that conflicts when main moves, or a reviewer's request. In Talyn, that stretch is the same session and the same button.
- Your pull requests as a set: a list ordered by what is blocked, a queue that lands the ready ones, or a rule that fires on every pull request in a repository.
Using both
Devin writes the change and opens the pull request. Talyn tracks it, fixes it when it drifts, and merges it when it is green. Talyn reads GitHub, so it does not matter which agent opened the pull request.
Which one
Use Devin if you want to assign a task, a ticket or a migration and get a pull request back without steering the work.
Use Talyn if you want to run several tasks at once on your own Claude or ChatGPT plan, watch and steer each one, and have the pull request carried through to merged.
