Simvyn – Universal mobile devtool, no SDK required
Consolidates a dozen fragmented dev tasks into one polished dashboard with CLI.

Custom WebRTC pipeline for device control, built for agentic testing workflows.

It's a mobile device cloud (like AWS Device Farm or BrowserStack) built mainly for agentic use cases, and with (much needed) UX improvements for manual interaction (built my own WebRTC to device pipeline).
I've spent pretty much all of last year working on autonomous QA agents for web and mobile testing. Earlier this year I realized a lot of devs started building their own agents (qa, rpa, scraping, etc) but drew the line at building the infra. I spent last week spinning out our mobile infra as a separate service and this is the result.
We also support Windows executables, macOS apps, and HTT2 tunnels (for access to private and localhost networks). These aren't exposed in the alpha but support for them does exist.
Try it out for free! If you have an iOS app, make sure it's built for the simulator (not the ipa file). If you need these at scale, let me know, we have a bunch of compute allocated already.
Thanks!

Unified iOS and Android device control, but Xcode/Android Studio already do most of this.
Self-hosted simulator streaming beats BrowserStack on privacy and recurring costs.
Solves IoT infrastructure friction, but Firebase IoT Core and AWS IoT already own this space.
Offline on-device RAG beats cloud-only competitors like NotebookLM.
They combined typed payload validation, per-device sequential mailboxes and JS Actions running inside a WASM sandbox — a practical feature set that actually improves predictability for fleet code. The tiny Rust agent plus Python/JS/Elixir SDKs and an Elixir+DuckDB backend signal thoughtful infra choices rather than vaporware. Nice UX on the landing page, but the space is crowded; integrations and real-world scale will determine whether this stands out.
