aper VS plane

The relevance here is that this post mentions their new Rust library Aper (https://aper.dev/). In addition, CRDTs are a favorite topic of Raph Levien, AKA the Rust GUI guy, and featured in the Xi editor, his first major Rust project (retrospective here: https://raphlinus.github.io/xi/2020/06/27/xi-retrospective.html).

It's also super refreshing to see the work on Aper [1] [2] (a Rust library implementing state machine synchronization across a trusted network). Looking forward next series of articles here!

Our Aper (https://aper.dev) implements a number of similar concepts (state machine replication with optimistic local transitions + rollback). I 100% agree that it’s an easier model to reason about.

Your approach with cursors is clever, that part I haven’t seen elsewhere.

We make Jamsocket (https://jamsocket.com/), which allows application developers to spin up and connect to server-side compute. This allows browser-based applications to do computationally-intensive things that are otherwise impossible in the browser.

We went through YC and just raised a seed round and are looking to build up our team. We are based in NYC but are open to remote for experience candidates.

Our tech stack includes Rust, NATS, Docker, Postgres, TypeScript.

We have lots of fun technical problems that get into the nitty-gritty of networking and operating systems, plus fun open-source stuff like Aper (https://aper.dev/). We are excited to build a diverse team and encourage non-traditional candidates to apply.

One reason I'm excited about this is that it appears to let you write arbitrary routing logic into a layer 7 proxy. This is something we had to build for https://plane.dev and it would have been nicer to use something like this, but we couldn't find anything like it at the time.

Of course, as a user, I would prefer as much as possible to be under MIT or Apache. See for instance https://plane.dev/ for a similar project which is MIT licensed and https://jamsocket.com/ for the commercial version.

From an earlier blog post[1], the system for synchronizing file/document state lives independently for their database. As I understand it, their database is for metadata rather than actual document content.

> It’s worth noting that we only use multiplayer for syncing changes to Figma documents. We also sync changes to a lot of other data (comments, users, teams, projects, etc.) but that is stored in Postgres, not our multiplayer system, and is synced with clients using a completely separate system that won’t be discussed in this article. Although these two systems are similar, they have separate implementations because of different tradeoffs around certain properties such as performance, offline availability, and security.

This post[2] goes into more detail on how they spin up backend processes to serve as the source of truth while documents are open (we took heavy inspiration from it when building https://plane.dev, which aims to be an open-source implementation of that architecture.)

We have been happily using Depot for months now to build https://plane.dev. Prior to finding Depot, we basically gave up on building an M1 image from a GitHub action.

(btw, I always get suspicious when a Show HN post has a lot of praise in the comments, but I swear the Depot folks did not ask me to post anything and I only saw the post because I was checking HN)

Congrats on the launch!

We've been using Depot with Plane (https://plane.dev/). Prior to depot, I had to disable arm64 builds because they slowed the build down so much (30m+) on GitHub's machines. With Depot, we get arm64 and amd64 images in ~2m.
