professionally obsessed with building — Mumbai

we make stuff we'd actually use.apps, odd little tools, a watch face.because we like it.

we're TheAppStack Labs — we make apps, odd little tools, and the occasional watch face, because building this stuff is the fun part. some took off, one we built and sold, the rest we just keep alive because we still like them. not an agency — we just really love doing this.

  • Best of Google Play (yeah, really)
  • 100K+ people downloaded our stuff

the stuff we build with — all of it, ourselves

What we build

we build the whole thing ourselves.

front to back, every layer. not because it's a service we sell — because we're picky, and the only way to get a thing exactly right is to build all of it yourself.

01

Mobile

Real native Android and iOS apps — not a website in a trench coat.

02

Desktop

macOS and Windows apps that feel right at home on both, off one shared core.

03

Wearables

Wear OS apps and watch faces for the tiny screen you check way too often.

04

Backend

Memory-safe Rust services that don't fall over when people actually show up.

we've built enough of these to know the difference between something that demos well and something you'd actually keep — so we just build the second kind.

stuff we've built

things we shipped (and still use).

this is the honest stuff — the things we made because we wanted them to exist. one of them we built, grew past 100,000 users, and sold. the rest we still run, with our name on it.

OpenAlly

the main one

AI Assistant · Android

the whole thing — gateway, agent runtime, messaging channels — runs right on your Android phone. no cloud account, no servers in the middle. this is the one we're most into, and it's got a home of its own at openally.ai.

ZyadaShop

built it, sold it

E-commerce SaaS · Android

any shop owner could spin up a real online store — catalogue, payments, instant sharing — in seconds. we designed it, built it, grew it past 100,000 downloads, and sold it. that last part still feels good.

Open source · 2026

built in the open.

stuff we wanted, couldn't find, and built anyway — then left out in the open for whoever wants it. a few things we put on GitHub in 2026, now humming away on machines of people we'll never meet.

OpenForge

An all-in-one trainer for offline single-player PC games — write your cheats in a TOML file instead of fighting Rust. Tauri 2 shell, UE5 reflection bridge, Lua scripting, global hotkeys.

Rust

Aster

Hand your Android phone to an AI over the Model Context Protocol — 40+ tools, from tapping the screen to making calls and firing off SMS. You host it, it stays yours.

work with us

we don't take clients. but sometimes we build with people.

only on stuff we'd actually want to own, though — built like it's ours, with real skin in the game. the full version of how that works is one click away.

say hi

got something you're itching to build?

tell us the thing you can't stop thinking about. if it's something we'd want to own too, we'll tell you straight how we'd build it — and whether it's a thing we'd actually want to make with you.

Mumbai · building from here, for everywhere

who's behind this

new name. not new at this.

TheAppStack Labs is the name. behind it: people who've been building things for a long time — shipping them, watching them break in ways we didn't see coming, figuring out exactly why, and not making that mistake twice.

we build across the whole stack — mobile, desktop, wearable, and the Rust services underneath — because the things we want to use don't live on just one platform. mostly we build what we'd want to own, and we build it like we have to live with it. because we do.

made in Mumbai. fuelled by coffee and the fear of shipping something we wouldn't use.

the human

Satyajit Pradhan.

builder · engineer · player‑one

the one behind all of this. has been shipping software since he was old enough to be told he should be doing his homework instead — and never really stopped. the apps, the open‑source experiments, the whole thing: one head, a lot of late nights.

equally happy designing a Rust service, soldering a sim‑racing rig, or redoing a feature at 2 a.m. because the old one was “fine” — and fine has never been the point.

  • been at this a while

    started young, never stopped. apps, games, telemetry bridges — it all runs on muscle memory now.

  • Lifelong gamer

    sim racing rig, MOZA wheel, controllers on every desk. half the side projects start from being annoyed at something mid-game.

  • Allergic to demos

    loves new products the way other people love football. the bar is shipped, not pitched — a slide deck doesn't count.
