Hi everyone, maker here. Tessar started with a frustration I think a lot of you will recognize. Every time I began a new system, I'd lose an afternoon to the same ritual — a vague brief, a dozen browser tabs, a half-finished diagram, and the creeping feeling that I was reinventing decisions I'd already made a hundred times before. The blank page was always the hardest part. So I built the thing I wished existed. You describe what you're building in plain English — something like "a subscription invoicing app for around 50,000 users, needs to be GST-compliant, serving India and the US" — and a few minutes later you get a proper architecture back. Not a vague paragraph, but a structured document: the components that actually matter, the diagrams, a monthly cost estimate, the risks worth worrying about, the security controls, and a roadmap to get there. The part I'm quietly proud of is the comparison mode. Instead of one answer, Tessar can design three or four competing architectures from the same brief and lay them next to each other — cheaper here, faster there, this one locks you into a vendor, that one scales further. You end up choosing with the trade-offs in front of you, the way a good architect actually thinks, rather than committing to the first plausible design and discovering the catch six months later. A note on what it isn't: it's an opinionated first draft, not a replacement for an experienced engineer. The point is to get you to 80% in a few minutes so you can spend your energy arguing with the last 20% — which is the interesting part anyway. The cost numbers are honest ranges, not vendor-exact quotes. If you'd like to see what it produces before signing up, there's a full sample report here: tessar.dev/sample. And if you want to run your own, the first design is on me — no card needed. What I'd love most from this community is the uncomfortable feedback: tell me where the architectures are wrong, where you'd have made a different call, what you'd never ship. That's far more useful to me right now than anything kind. I'll be around all day to talk through any of it.
