Your agents should belong to you.

Not to a company. Not to a subscription. To you, on the machine in front of you.

Everything that knows you
lives somewhere else.

Your work. Your habits. Your half‑finished thoughts.
All of it a guest in someone else's building.

They set the rent. They read the mail.
They can ask you to leave.

We think that is the wrong way round.

How

So none of it leaves your Mac.

Bloks runs entirely on your Mac. Your agents, your conversations and your keys sit in ~/.bloks on your disk. There is no Bloks account, because there is no Bloks server to hold one.

The only thing that leaves this machine is the engine you picked, talking to the provider you already pay. Bloks is not in the middle.

No account

Bloks never asks who you are. No sign-up, no email, nothing to make.

It asks first

When an agent wants to do something that matters, it stops and waits for you.

Nothing hidden

A skill is just markdown. You read all of it before it goes near an agent.

Yours to keep

Read every line, build it yourself, run it at any company size. One limit: do not sell Bloks as Bloks.

Who

Setting one up is one question long.

Pick a role and it is made on the spot, named for the job, carrying that role’s skills. Or describe the job in a sentence and Bloks proposes the name, yours to change. Either way the agent opens with one question about how you want to work together, then gets on with it.

What

And what you get is a messaging app.

An agent is a contact. A room is a group chat. Give one a job, then add another when the work grows: one on the launch, one on research, one on the inbox. They work in parallel, hand things to each other in rooms, and whoever you made most senior speaks last.

This is the app itself, photographed. The same workspace on the Mac and on the iPhone, down to the approval card waiting for one tap.

Engines

Runs on what you already pay for.

Bring your own. CLI agents you already installed, an API key you already pay for, or a local model. Nearly every engine runs tools: it executes commands, touches files, and acts. Bloks marks the exceptions everywhere it shows one.

Engines are picked per agent and switchable mid-conversation; Bloks replays the story to the new engine, so nothing is lost in the move.

FAQ

Fair questions, short answers.

Is the desktop app really free?

Yes. Your own API keys, unlimited agents, no seat count, no expiry. It is not a trial and never turns into one. The source is public under FSL‑1.1‑MIT, so this is checkable rather than promised.

Where does my data live?

In ~/.bloks on your Mac: conversations, agent memory, keys, all of it. Back the folder up, move it to another machine, or delete it and be genuinely rid of the app. There is no Bloks account and no Bloks server holding a copy.

Do I need an API key?

You need at least one engine. If Claude Code, Codex or another agent CLI is already installed and signed in, that counts and no key is needed. Otherwise paste any provider key, sign into OpenRouter from Settings, or run Ollama.

What can agents actually do?

On a tool-running engine: read and write files, run commands, browse, use apps you have connected, and keep notes in their own memory. Anything consequential stops and asks you first, on the Mac or on your phone.

Can agents work together?

Yes. Put them in a room and address one with @name or just talk. Juniors answer first, the most senior speaks last, and they can hand work to each other mid-thread. Teams you like can be saved and rehired.

Can I connect my own tools?

Three ways. Connect apps like Slack or Gmail through the built-in connector cards, register any MCP server you already use, or let an agent request an API key with a secure field in the chat. Keys are stored on your Mac and never appear in the conversation.

What happens when I close the laptop?

Today, agents pause with it; scheduled runs skip rather than pile up. Bloks Cloud is the answer to exactly this: the same agents hosted, working while the lid is shut, with your phone as the remote. The waitlist below hears about it first.

Is Bloks in the middle of my provider traffic?

No. The engine you picked talks to the provider you pay, directly. Bloks orchestrates on your machine and resells nothing, marks up nothing, and cannot read what it does not carry.

Next

Agents that keep working after you shut the lid.

All of this runs while your Mac is awake. Next is hosted: the same agents, the same rooms, still your own keys, answering you from your phone while the laptop is shut.

One email when it opens, nothing else. Or watch releases on GitHub; every version lands there first.
