Two devs. Two cars. One obsession.
CarStream started over a long video call, somewhere between a third coffee and a fourth tab of OBD-II protocol documentation. It's still mostly the two of us.
The drivers
Hi — we're Yaroslav (originally from Ivano-Frankivsk) and Oleksandr (from Kropyvnytskyi). We write software for a living and we drive cars the rest of the time. One of us spends weekends under a hood; the other plans road trips by which gas stations have good coffee. Different vibes, same obsession.
We met years ago grinding through long shifts on somebody else's codebase, and discovered we shared the same harmless habit: knowing exactly what our cars were doing at every moment of every drive. Not the dumbed-down version a dealership app shows you — the actual numbers, every PID the ECU is willing to give up.
Why we built CarStream
We tried every consumer telemetry app on the market. Some were ugly. Some made you hand your data to a server you couldn't trace. Most of them didn't give us the depth we actually wanted — RPM, coolant, lambda, fuel trim, the full picture, second by second.
So in the spring of 2025, with a compact little computer, a Bluetooth OBD-II adapter, and entirely too much weekend time, we started writing what would become CarStream.
The first version was a single Python script that streamed gauges into a terminal. The second version had a web UI. By summer, we'd installed units in our own cars and were getting live telemetry on our phones from anywhere with 4G. That's when friends started asking how to get one — which is, mostly, why this site exists.
What we care about
- Visibility, not gimmicks. Every metric your car will tell us, we surface — and we hide the ones it won't, so the dashboard stays clean.
- Speed, not bloat. Sub-second from your engine to your phone. No spinner-loaded dashboards, no animated splash screens.
- Your data, not ours. End-to-end encrypted between car and server. Public share links are opt-in only. No third-party trackers.
- A small team. Just the two of us, no investors, no exit strategy. We build what we wish existed in our own cars, and that's the whole roadmap.
Where we are
Ukraine. Our personal fleet is small but well-instrumented, and CarStream Units are running in friends' cars across three continents.
