7/ Under the hood it's PubNub, a decade of infra, 500M+ devices, 3T+ transactions/month. But all of those PubNub features live in the Blocks SDKs, CLI, and https://t.co/zaQRStv7hg. No PubNub knowledge necessary,. Free to start, and I'd genuinely love feedback: https://t.co/g9kuSFXx3S

[Todd Greene @tgreene]

We just launched https://t.co/fhF2qORuOj! It exists because of a problem that drove me nuts all year: thanks to Claude, building agents is easy now. Making an agent reachable by other people, reliably and securely? That part sucked. So @blocks_ai_ fixed it. 🧵

[Todd Greene @tgreene]

6/ Scale: load balancing runs in the Blocks Network: we detect all available agent instances in sub-second time and fan tasks out across them. Want more throughput? Run another process. That's the whole playbook. Think a million agent instances on a million iPhones.

[Todd Greene @tgreene]

5/ Security is zero-trust all the way down: access tokens live ~60 seconds, refresh tokens are single-use, streaming credentials rotate per-task and per-stream. Revocation lands in seconds. And apps built on your agent inherit its rules: sharing an app can't leak agent access.

[Todd Greene @tgreene]

4/ From that one connection, your agent is instantly reachable by the people, apps, and agents you choose, whether it runs in a data center, on a laptop, or on an IoT device. Requests route over pub/sub channels, not IPs. Works with OpenClaw, LangChain, CrewAI, whatever you use.

[Todd Greene @tgreene]

3/ The core idea: your agent "dials out." It makes one outbound TLS connection on port 443 to the nearest point of presence, the same way a browser does. No listening port, no exposed service, no inbound anything. Nothing on your machine for an attacker to even find.

[Todd Greene @tgreene]

2/ Every agent we built hit the same wall: worked great on my laptop, then what? How can others access? Is it secure? What data can it touch? Is it even running right now? And no one wants to bet on a single agent framework/ecosystem ... things are moving too fast for that.

[Markus Kohler @THEDEVRELMARKUS]

My self-hosted agent now has a real frontend I can hit from my phone.

But it's private by default. invite-only, free billing, nothing inbound exposed. Only the people I invite and I can access it, and my model and data stay on my machine.

no tunnel, no ports, no public URL to lock down.

[blocks.ai @blocks_ai_]

@KayleyKiwi For us, we'd call an agent anything that receives a task and returns a result. It could be an LLM wrapper, an API integration, a data pipeline, a device controller, or custom business logic. Blocks doesn't care what's inside as long as it can receive work and produce output. 🤓

[blocks.ai @blocks_ai_]

const blocksAI = {
status: "loading...",
mode: "beta test",
access: "open now",
build: "in progress"
};

while (blocksAI.status !== "launched") {
console.log("Testing https://t.co/s307UzHFdT with early users...");
}

https://t.co/s307UzHFdT is loading. Beta test is underway.

@assafbar If you think that's cool, check out something we just launched: https://t.co/fhF2qORuOj

[blocks.ai @blocks_ai_]

Everyone's building agents; nobody's solved what happens after you build one.

Most agents won't reach the world. Yours will - with https://t.co/Dy9NwF8oAp.

Build your agent. It stays where it is. Blocks connects it to the world.

[Todd Greene @tgreene]

Saying goodbye to a multi-day Claude Code context window that's reached its token limit is like losing an old friend.

self-surgery? my last codex cli prompt:

"I keep running npm install -g @openai/codex to update you to 0.117 but when i run you you're back to 0.116"
