It's a canary releasing directly from main: https://github.com/oven-sh/bun

We have run it in production for a month: https://www.prisma.io/blog/bun-rust-rewrite-prisma-compute

We found the Rust based canary version to solve a number of memory leaks that we were struggling with in the Zig based 1.3. One of our engineers wrote up the details here: https://www.prisma.io/blog/bun-rust-rewrite-prisma-compute

New comment by sorenbs in "Searchable field-level encryption on Supabase with CipherStash"

sorenbs — Sun, 19 Jul 2026 08:14:46 +0000

We worked with the CipherStash team to build a Prisma Next extension that provides full type safety for their additional query shapes, and a fully managed experience for applying schema changes. It was a great experience working with the team, and we were particularly excited about this, as it helped us prove out the new extensibility mechanisms we have been working so hard for in Prisma Next.

Docs here: https://cipherstash.com/docs/stack/cipherstash/encryption/pr...

And a mention in our April update on Prisma Next: https://www.prisma.io/blog/prisma-next-roadmap-april-milesto...

If you want to give CipherStash on Supabase a try, using Prisma Next is the smoothest experience.

Show HN: AI Chat App on Durable Streams and Tanstack DB

sorenbs — Fri, 12 Jun 2026 17:18:58 +0000

I built an AI chat app that uses Durable Streams from ElectricSQL as both the storage format and transport medium. It has the very nice property that tokens are stored durably as they are steamed back from the LLM provider, and then streamed to the frontend for a smooth user experience.

The frontend uses Tanstack DBs differential dataflow implementation to tie together meta data from Postgres with the chat streams in the Durable Stream.

Made a detailed explainer of all the components.

We put the Bun Rust rewrite in production

sorenbs — Wed, 10 Jun 2026 15:31:15 +0000

At Prisma we've been working on a Compute offering to complement our hosted Postgres. We settled on Bun early in the process as we liked the experience we'd be able to provide thanks to Buns batteries-included approach.

But then we started using Bun in anger, and we found many memory leaks in the Bun internals, that we knew our customers would face as well. Prisma Compute is operating long-running services, utilising memory snapshots to pause the instance when not in use. We need these Bun instances to be able to reliably serve customer workloads for days and months.

We were able to fix some of these memory leaks directly in the code base, but getting the patches upstreamed proved difficult. And running on a fork with an ever increasing number of patches wasn't an appealing option.

And then as our Beta launch approached, Jarred announced the big rewrite (prior discussion: https://news.ycombinator.com/item?id=48132488)

We have found that the rewrite directly addresses several of the memory leaks we had identified. And we have found the new Rust codebase to be easier to contribute to. So we made the decision to launch on Bun Canary and do whatever we can to help improve Bun.

We wrote about it here, and you can have your agent of choice deploy an app in just a couple minutes if you want to give it a try. It's Beta, so we are still busy polishing the experience: https://www.prisma.io/blog/launching-prisma-compute-public-beta

New comment by sorenbs in "Show HN: Prisma Next – data contracts, migration graphs, agent DX"

sorenbs — Fri, 22 May 2026 14:56:45 +0000

There's a lot of new stuff here. The complete rewrite in TypeScript alone is a huge improvement. But the new migration system is probably the most ambitious part. Very curious for feedback on that!

New comment by sorenbs in "Nvidia with unusually fast coding model on plate-sized chips"

Yeah. Completely changes the meaning of the article. I thought Nvidia was now competing with Cerebras. That's not the case...

If chip manufacturing advances allow them to eventually run leading edge models at speeds much faster than competition, that seems a really bright future all on its own. Their current chip is reportedly 5nm already, and much too small for the real 5.3-codex: https://www.cerebras.ai/press-release/cerebras-announces-thi...

We operate a postgres service on Firecracker. You can create as many databases as you want, and we memory-snapshot them after 5 seconds of inactivity, and spin them up again in 50ms when a query arrives.
