The short answer

Which one is for you

Choose Bloks ifOur pick

  • You want agents for more than code: research, admin, support and your home, as a team in a room.
  • You want agents that ask before acting, and changes you can undo.
  • You want to mix engines: Claude Code, Codex and Devin itself, each on your own sign-in.
  • You want conversations and memory kept on your own computer.
  • You want an iPhone and Apple Watch app today.

Choose Devin if

  • You want the deepest coding agent here: cloud machines that take tickets and migrations to pull requests and fix CI.
  • You want work to start from Slack, Teams, GitHub, GitLab, Linear or Jira.
  • You want many sessions at once on cloud machines (Linux, Windows or macOS) that run while your laptop is off.
  • You need Enterprise options: a private VPC, self-hosted Outposts, air-gapped builds, SSO and SOC 2 Type II.

Devin inside Bloks

Bloks

Devin is one of Bloks's engines. Settings, Engines and keys installs Devin's CLI with one button, you sign in with your Devin account, and an agent on Devin works in your folders like one on Claude Code or Codex. It gets the agent's own browser and its computer as tools, asks before acting the way every Bloks agent does, and its changes can be undone.

So the choice need not be either or: put a Devin agent in a room beside Claude Code and Codex agents, or give it a backup engine for when it runs out.

Settings, Engines and keys in Bloks: Claude Code connected, the other engines one button away

Devin

Devin on its own is a family of apps: cloud sessions in the browser, Devin Desktop (formerly Windsurf) for Mac, Windows and Linux, a CLI that also runs in JetBrains, Zed and Xcode, and code review. A command centre shows your local and cloud agents together, and its CLI can bring in settings from Cursor, Claude Code, Copilot and others.

Where Devin is ahead: code and integrations

Bloks

Bloks is a home for agents of every kind rather than a coding service. Its coding agents work in your folders, each with a terminal, and bloks-server run hands one a job from a script or GitHub Actions. Webhooks, app watchers and workflows start work from outside events, and rooms can be carried into Slack and Discord.

DevinBetter

Devin is built for software work and goes further there. Its cloud sessions run on Linux, Windows or macOS machines, take tickets and migrations through to pull requests, and fix CI on the way, many at a time. Work starts from Slack, Teams, GitHub, GitLab, Linear and Jira, or a schedule or webhook, and an API and MCP server open sessions and knowledge to other tools. For a company, Enterprise adds a private VPC, self-hosted Outposts and air-gapped builds.

Safety, undo and your data

BloksBetter

An agent in Bloks asks before it acts, unless you tell it not to, and you can write rules in a sentence. Anything it changes in your files can be undone, a conversation can be rewound, and any answer can be branched. Work that should not touch your machine can run in a Docker container or on another machine over SSH.

Conversations and memory stay on your computer. An engine you choose, Devin included, follows its own terms for what it sees.

A changes card in Bloks: the files an agent changed, each one with Undo

Devin

Devin's local agents have allow, ask and deny permissions, with a sandbox at the system level in the CLI, and Security Profiles limit network, MCP and git access. Cloud sessions work on their own in an isolated machine, without approval for each step by default. An undo is not published.

Cloud data is encrypted in AWS, under SOC 2 Type II. Training on your data is on by default: paid plans can opt out, which also turns on zero retention with model providers, and the Free plan cannot. Data is kept for as long as you are a customer.

Price and licence

Bloks

Bloks is free with your own AI, with no limit on agents, and never stops working without a plan. Paid plans add reach from anywhere, people in your workspaces and an included AI; see pricing. Its source is public under the Functional Source License: free for any use, including at work, except selling Bloks, and every release becomes MIT two years after it ships.

Devin

Devin has a Free plan, Pro at $20 a month, Max at $200 a month, Teams from $80 a month and custom Enterprise pricing. Quotas refresh daily and weekly, and use beyond them is billed at API rates, so a month's cost depends on how much you run. It is proprietary.

Questions

Bloks and Devin: questions

Is Bloks a Devin alternative?

For some work. Devin is a coding service with cloud machines and deep ties to engineering tools. Bloks is a desktop app for a team of agents doing any work, with approvals and undo, and it can run Devin as one of them.

Can Bloks run Devin?

Yes. Settings, Engines and keys installs Devin's CLI with one button, you sign in with your Devin account, and an agent on Devin works in your folders with the Bloks browser and its computer as tools.

Does Devin train on my code?

Cognition's security page says training is on by default. Paid plans can opt out, which also turns on zero retention with model providers; the Free plan cannot. Bloks keeps conversations on your computer, and an engine you choose follows its own terms.

Does Devin ask before it acts?

Its local agents can: they have allow, ask and deny permissions. Cloud sessions work on their own in an isolated machine by default. Bloks agents ask first unless you choose otherwise, and their changes can be undone.

Which keeps working when my laptop is closed?

Devin's cloud sessions do. Bloks agents do when they run on a server of yours with bloks-server, or on managed hosting.

Is there a phone app?

Bloks has an iPhone and Apple Watch app on the App Store. Devin's iPhone app is a beta with a waitlist.
