Bun v1.4.4 is now running all new deployments on Prisma Compute Bun v1.4.4 no longer trusts certificates from the compromised eMudhra intermediate certificate. Apps on Prisma are protected against forged HTTPS certificates made with those leaked keys

This change was done via Slack on my phone talking to our coding agent. I could have shipped it Saturday morning but didn't want any weekend surprises. 2026 is wild

Apps deployed to Prisma now receive a `Prisma-Connecting-IP` HTTP header Yesterday we had a user ask for a way to receive the external request IP, which was obviously needed, so as of this morning we have it. Keep giving us feedback and we'll keep improving

The biggest risk in software development today with AI might be asking the agent to change something that contradicts an assumption about your product that lives only in your head and some disposable agent thread

I'm letting fable run unhinged in a VM to evaluate experiments with firecracker. Last night it was working on VM networking in a rust harness that bans unsafe. It wrote C code instead, compiled it to BPF, and copied the bytes into a Rust source file. Absolutely ruthless

We've been building our own agents to help us operationally and they all run on open weight models, mostly GLM The newest is a code review agent that runs GLM-5.3 Flash. The Prisma team is already favoring it over the one we pay for and the core was built in a couple afternoons

The code review agent starts from a GitHub webhook, grabs some context, clones into a sandbox, generates a git diff, then gives the sandbox to an agent to perform the review

Tyler Benfield
@rtbenfield.dev

The agent has tools to report feedback and mark files as complete. If it ends the review without all files marked complete, a guard makes it continue. This all happens in a Mastra workflow. A few more things for replying to comments and such, but that's the gist of it

We use Mastra for its excellent primitives and telemetry. It gives us a good foundation, is model agnostic, and improves every week. The skill and docs are great, so we unleash our agents to build agents. Highly recommend

You already have tools for self improving software Set up a Claude or Codex routine to pull your errors, telemetry, or product metrics and generate a report that includes prompts or creates PRs directly to fix the biggest issues. Every day your product gets better

Tyler Benfield
@rtbenfield.dev

Giving agents paths to access data over MCP or other tools is insanely cool I have Claude routines running daily to generate reports on our infra and look for opportunities for improvement. If something seems off I can ask it to dive deeper, look for historic patterns, or find correlating trends

This morning we shipped a fix to Prisma Postgres connection routing to address an increased p99 network latency that sometimes resulted in timeouts on p99.9

One thing we added is a daily agent workflow to analyze telemetry, generate a human-friendly report, and propose improvements with comprehensive prompts. It also verifies post-fix This will soon mature to dispatching coding agents to create the PRs autonomously

Tyler Benfield
@rtbenfield.dev

A human will still make the deployment decision, but this substantially improves our ability to react to small deviations in measurement and in ways that are challenging to predict ahead of time to create alerts for Agents shine in catching and fixing the 1 in 10k issues

This had been slowly creeping up over the last few weeks disguised as intermittent network inconsistencies. We've found the root cause, fixed it, and we're improving our observability to spot and correct these trends much earlier

In the last year we've gone from tab completion to watching agents take tasks, write code, and verify their work. It's hard to grasp how quickly this shift happened and obvious that it's not over yet

Prisma@prisma.io

The next million products will be built on a stack that works as one. We’re building Prisma so builders and agents can move from prompt to product in one continuous loop. This is the next chapter of Prisma. pris.ly/new-prisma-bs

Prisma ORM was always about helping developers write reliable code faster. The next iteration of the ORM extends that with agents as a first class consumer Prisma Cloud brings that same passion into how humans and agents build and deploy. Low friction, reliable guardrails, and explicit feedback

We're still early and the next year of industry changes is hard to predict, but we'll be right there experimenting, adapting, and shipping to give you the best platform we can imagine for 2026 and beyond

Apps hosted on Prisma Cloud now have automated response compression This is spec-compliant and passes through already compressed assets. You can optimize your build-time assets while letting us compress server rendered pages or opt-out with `Cache-Control: no-transform`

Since Prisma 8 has pluggable data types we can ship options with zero cost Temporal is the recommended option if you like working code. String values will be available if you're nostalgic for time zone bugs

Tyler Benfield@rtbenfield.dev

How would you feel if Prisma 8 required your JS runtime to support the Temporal API or provide an implementation like temporal-polyfill?

As models get better and we're encouraged to cut back our rules files, the most durable ones are describing intent and product direction Aligning with AI on this enables the agent to make meaningful suggestions and even push back
