One binary to run and you have a full backend at your fingertips: a database with a REST API, sign-in, realtime, files, server-side hooks and jobs, on SQLite or Postgres. It's MIT licensed. You can try the demo at https://demo.vaultbase.sh (the login is filled in, and it resets every hour). I built it to ship fast. I always tend to write the same logic for any new project, whether it's a side project or a small to medium project for a client. I wanted something my friends and I could work with fast, try new things with, and that's easy to use. Then it became something I really wanted to work on and make as complete as I can for any type of backend. As of writing this post it has 80 releases since May this year and is backed by more than 2,800 tests. I also run security reviews with Claude and fix what they find. It hasn't had an outside audit yet. It was built with the help of Claude, from the codebase to the documentation and fact-checking it against the code. Claude helped speed up the pace, find bugs, and write tests. Vaultbase is pre-1.0, so expect some bugs and issues here and there. I'm working hard to fix each and every one of them. Thank you for taking the time to read this. I'd really appreciate any feedback, even if you didn't like Vaultbase. The demo is yours to try, and it's two commands to run locally.

Hi HN, we're Zach and Evan, founders of Rystic (https://www.rystic.ai). As LLMs have progressed, producing code has become fast and cheap but verification has not. At my previous company I noticed that whenever I could test a service locally or in CI this bottleneck went away. If a service needed to use a shared sandbox or staging environment to run integration tests, verification was a huge pain. At Rystic we are taking that idea and applying it to every third-party service. We are trying to give developers a way to verify that their code works without calling real systems.

To do this, we build deterministic simulators of APIs like Slack, Stripe and S3. You can control these locally; set their state and inspect it. Our aim is to make these a controllable stand-in for the real service, much more so than any sandbox. For this we offer fault injection, latency injection and multiple actor support. So for example you can cancel a subscription mid-cycle as the customer in the billing portal, then check that your app handles the proration and removes access. In the Stripe sandbox someone has to click through the portal by hand.

We recreate these applications as Go binaries to make them performant. A single simulator can handle thousands of requests per second. You can even control whether they get rate limited or not depending on how realistic you want your test to be.

To make the simulators we construct a set of tests based on their docs, probe their API, gather traces then use that to reverse engineer the state transitions of the application. Then we iterate on this by running deterministic tests and actively trying to break it. Proving this state machine is the same as the original would be NP hard but we can still show that they are equivalent over several hundred multi-step workflows. To make sure that our version stays accurate we test every night to catch drift and repair it. Each simulator's fidelity card lists its score, which is how closely it matches the real API across those workflows, and we share the failing tests with customers: https://www.rystic.ai/simulators

It is frustrating to have these incredibly powerful tools for producing code but then be left with the annoying work of verifying that what is produced actually works. No one wants to spend their day finding API keys, setting up sandbox accounts and manually clicking through applications. We are trying to make a future where that does not happen, where you can move fast and not break things.

We would love for you to give it a try. Any feedback is very welcome.

hi HN!

I built Mimzie, an agent neutral AI workspace inspired by the Claude Suite (Docs, Sheets, Slides) and Cowork.

It's a free desktop app that runs ChatGPT, Claude, Gemini, and Grok in their native CLI harnesses. Think T3 Code or Conductor but for knowledge work. It's basically a GUI for managing knowledge work agents in various form factors. One of those form factors is Bots, akin to Grok Bot or Dots.

The original idea for mimzie was simple: I pay for Claude and ChatGPT, and a lot of my day-to-day work lives in .xlsx, .pptx and .docx files. Moreover, I was sick and tired of losing context between AI platforms. I didn't want to bet the house on one AI lab's product, be it the ChatGPT or the Claude Desktop app.

So I built an AI desktop app that was agent neutral.

The goal of mimzie is to bring the kind of agent workflows that devs have had with codex and claude code into the hands of everyone. And to have a friendly GUI to do it. I've found that the personal agents, hermes and openclaw, are intimidating to set up and confusing to the average non-technical person.

some of the core principles of mimzie:

- your file stays your file: edits are done locally and .docx, .pptx, .xlsx, and .md and synced to the cloud after - every change is reviewable: edits show up as tracked diffs that you accept or reject, at the smallest unit that makes sense (e.g. a sentence in .docx) - free, and no new subscription needed: bring whichever AI plan or plans you already have. You shouldn't have to pay twice for the same inference, and you SHOULD take advantage of the insane subsidization in the current ChatGPT and Claude plans. - Bots with any AI: I love the concept of grok bot, not so much its limited choice of models. I strongly believe that long-standing "ai teammates" should be agent neutral and in your control

Try mimzie out: it's a free beta at mimzie.com

it's early, lots of rough edges, but I've had the time of my life developing it.

I'd love to answer questions and hear any and all feedback.
