Durable Actors:

[Thomas Karatzas @karatzas_thomas]

I built a tiny Lovable with @pidotdev durable, @modal and @IncTerse Durable Actors.

Should I keep building this and make it a series? Maybe it becomes a software factory

[Terse Inc @IncTerse]

The age of the Actor is upon us. Come build some great demos with Durable Actors!

[Thomas Karatzas @karatzas_thomas]

@IncTerse is throwing the first (to our knowledge) Actor Hackathon at @ycombinator!

Join us October 31st and build same scary good agents, drink some coffee made by me, and build alongside the top builders in SF.

Prizes include:
- Guaranteed YC Interview
- iPhone duo
- Mac mini
- more to be announced soon!

Most common question I get is how @IncTerse Durable Actors are different from Cloudflare’s Durable Objects (besides us being open source).

Here are the main differences 🧵

[Thomas Karatzas @karatzas_thomas]

Why you should host your agents on Actors. Preferably Durable Actors 👀

[Terse Inc @IncTerse]

A groundbreaking 3 people knew what an actor was! (new record)

[Olivier Simard-Morissette @oliviersm199]

great time demoing @IncTerse durable-actors at @omnaraai demo night. Congrats on the new office!

[Terse Inc @IncTerse]

🐍 support is upon us

[Olivier Simard-Morissette @oliviersm199]

one of the most requested features for durable-actors is Python SDK support. happy to announce it's finally here!

check out code + link to durable-actors in 🧵

These are the kinds of cool things you can build with me.

Every conversation is a durable Actor. This allows:

- only one person to be able to talk a time
- make the conversation go idle, and when you talk to character again, bring up the history as it was.
- fan out speech to all characters in the conversation easily.

And within the actor, a lot of cool logic. Namely:

- We use @typesafeai Jev to decide what info to divulge to you! (this is a murder mystery after all)
- @ElevenLabs to do text to speech.

Everything is dynamic! No two playthroughs are the same.

Oh and the front end is fully vibe coded with astra + @threejs.

[Olivier Simard-Morissette @oliviersm199]

we released durable-actors and are looking for the best way to stress test our infra.

we decided to build a multiplayer mystery game set in Victorian England powered by Durable Actors, @typesafeai Jev and @ElevenLabs.

Did pretty well for a distributed systems demo going against robotic arms playing Doom imo

[Thomas Karatzas @karatzas_thomas]

Demo showing how you can coordinate agents with Durable Actors!

This almost won me the @ycombinator demo showcase.

lost in the finals to a robotic arm playing Doom 😭

[Thomas Karatzas @karatzas_thomas]

was on the first page of @hackernews for most of the day yesterday!

[Khaliq Gant @Khaliqgant]

Had dinner with the @IncTerse guys @karatzas_thomas and @oliviersm199. So much of what they’re doing just makes so much sense from first principles. For agent native software it’s a near perfect match. We’re moving over to their tech for @agent_relay and I’m super excited for it.

Terse can’t miss!

[Thomas Karatzas @karatzas_thomas]

Introducing Durable Actors: Open source alternative of Durable Objects built for agent fleets and multiplayer AI.

Some key differences:
- configurable RAM, CPU and data residency per actor
- persist object properties durably by default
- we don't interleave requests on await by default
- allow exporting SQLite tables and offer fine grained o11y with CLI + MCP

i hear durable storage is so hot right now...

[Terse Inc @IncTerse]

@derekdfulton depends on fan-out. thousands of connections to a single actor, $0 egress is hard to beat. many DO, each with a couple users connected, uptime duration is the main cost, even with hibernation.

[Terse Inc @IncTerse]

It's time. Excited to help you build great multiplayer and agent coordination systems.

This is just the start.

[Thomas Karatzas @karatzas_thomas]

Terse is joining the YC F26 batch!

We are the open-source alternative to Cloudflare's Durable Objects, with configurable compute, data residency guarantees, direct access to Sqlite storage, a multi-tenant environment and concurrency safety by default.

And it's very fast!

[Terse Inc @IncTerse]

@derekdfulton GCP! Helm chart included in the repo!

Would love to know what you think

[Terse Inc @IncTerse]

@derekdfulton Configurable compute (no more crashes at 128MiB) + data residency guarantees + more fine grained 011y

[Terse Inc @IncTerse]

Caffeine and sandboxes, what else do y'a need?

[Nico Lecomte @NicolasLec91112]

Good luck F26!

iced coffee was on us today. the caliber is honestly insane, these companies look so much further along at day one than our batch was

just a few that stood out to me: @Simulithic, Plek AI, @IncTerse, Podesto…

[Terse Inc @IncTerse]

I am now a little (more) durable

[Olivier Simard-Morissette @oliviersm199]

we added durable retries to little-durable.

classify errors + exponential backoff

[Terse Inc @IncTerse]

Something new is coming, more details soon 🕵️‍♂️

[Thomas Karatzas @karatzas_thomas]

Action shot of me demoing something new we've been cooking at the presidio theatre.

@kevinrose don't worry, this will for sure be open source!
