mylittlechart v1 is almost entirely open-source — the renderer, the state bus, the agent API, the exchange connectors. The only exception is the quant module. The project is sustained by its sponsors while the beta runs.
Desktop charting terminal. Rust + WebGPU renderer, local HTTP API, tiered keys, indicator runtime. Everything you see in the screenshots is in this repo — build it yourself, patch it, ship your own fork.
What's open, what's not
We'd rather you know up front than find out in the license file.
The renderer, state bus, agent API, indicator runtime, exchange connectors, and UI shell. Build, fork, ship your own.
The quant runtime ships inside our signed binary. Same binary, still free to use — just not part of the source drop.
v2 is a ground-up rebuild with a different interface and a different deal. Fully proprietary. Not a successor to v1 — a different product.

Beta access
No feature gates. No paywall. Accounts exist for one reason right now: while the beta is moving fast, we push new builds straight to signed-in users instead of asking you to rebuild from source every time.
Sign in with GitHub. We register your install, and every new build lands automatically — usually a few days ahead of the next release on the repo. Sign out any time; the binary still runs, you just stop getting pushes.
Sponsor
The project is free. The exchange feeds aren't. If mylittlechart is part of how you read the market, consider chipping in — pick whichever channel is least annoying for you.
The normal route. Shows up on the repo, tax-handled, one click.
sponsor on github →Pay once, move on. Goes to a mug, a bug-fix weekend, and server bills.
buymeacoffee →Для тех, кому GitHub Sponsors не заходит. Та же подписка, другой шлюз.
boosty →One tier, one price. You get our sincere thanks — and, when we ship the in-app agent customizer, a Supporter-only icon set for your agents (different little wizard hats, honestly). No functional gating. The product is the same for everyone.
Asked and answered
Yes. MIT. Fork it, embed it, ship it inside your own product. Attribution is nice, not required.
It's the one piece of the project that would go from "a charting terminal with an API" to "a full auto-trader" if it were lifted out and re-glued. We're not comfortable with that being a one-weekend project. It's still free to use — the binary just carries it pre-compiled.
v1 keeps receiving fixes and lives on as an open-source project. v2 is a different interface and a different license — if you're happy with v1, stay on v1.
No. Download, run, done. The account only exists so we can push OTA beta builds to you. Same binary either way.
No — and we want to be careful about this. Everything the app does today, it does for free. Supporters get our thanks, and a cosmetic customizer for agent icons when that ships. If we ever change that, it'll be loud.
