Developer experience via docs

I was looking to use Rivet for our AWS marketplace billing metering but there are quite a few edge cases with the dev ex that I'd be uncomfortable having my team go manage. Happy to show you the use case and where I'm getting hung up if that's helpful for your product development 🙂

Recommended actor versioning pattern

What is the recommended pattern for handling actor's code and state mismatch after releasing a new version of my app (the new code produces different state)? If I understand correctly the state is always persisted, but the code that interacts with the state can change when actor upgrades it's version. Is doing a state migration onWake the correct solution here? For my usecase I don't really need actor's state - I could just use vars, because the data will be persisted into a separate database. Doing this would keep the "state"<->code in sync after a release, but it looks like a total antipattern. I'm totally new to actors and DOs, so I'm sorry if I'm missing something totally obvious. I need some guidance on this issue 🙏...

I can't connet to Railway using the dashboard

I've created a RivetKit app, deployed to Railway (it's just the server, using hono). Super similar to this. Then I logged in to Rivet dashboard, selected Railway under "Connect Existing Project", got the 3 credentials there and pasted them in my Railway app. But I'm stuck in this loading. Any recs of how to fix it? Not sure how to proced, docs are not very clear here......

Actor not found

We're using Rivet deployed on Cloudflare Workers and at around 15:40 UTC today (2025-11-20) we started getting "Actor not found" for 25% of our calls when calling our actors via getForId. The issue seems to have resolve itself after a new workers deploy 5 hours later; wondering if y'all have encountered this before? I'm assuming it's some transient Durable Objects issue.

Rivet slower than vanilla durable objects

I'm testing moving my current workload from vanilla durable objects to rivet + durable objects. I am seeing an extra 500-1000ms second of startup latency. Is that surprising to you? Am I doing something wrong?

Background jobs queue management and cleanup?

Couldn't find any useful info in the docs about this. Basically I am reproducing the Background jobs example. I am wondering: 1. queue in this example is basically useless? 2. jobs record will basically grows indefinitely? How would you recommend cleaning it up? Anything native to rivetkit? ...

External Client

Hey team, I'm trying to migrate my app from partykit to Rivet on Vercel functions. I need to accept a media stream from Twilio. I can't seem to figure out how this is best done in Rivet. I have a Convex backend and NextJS api routes as possible backend solutions - neither one is capable of upgrading a WebSocket request....

Coolify Template

Hello rivet team, are there any plans for having a Rivet template available on Coolify? It would be fully awesome to also have a one-click deploy of Rivet but on your own server instead of a managed service Lot's of Services like Appwrite, Supabase, even analytics tool have templates available on Coolify See the list here: https://coolify.io/docs/services/overview...

Deploying to cloudflare using wrangler vite

Hello everyone, came across this project and love how it solves every pain points i have had with dos. And the option to migrate off to your own cloud and not being vendor locked was awesome. While i was a lot to deploy it using the example I wasn’t able to get it working using the Cloudflare wrangler vite plugin. Can anyone help or have a boiler plate using the vite plugin.
