DepthSight

Self-hosted visual engine for algo trading

June 19, 2026 Just open-sourced a 280k LOC visual engine after a year of solo building

Hey Indie Hackers! Today is a huge milestone for me. After a year of intense solo development, I finally hit "Public" on DepthSight — a self-hosted visual architecture for high-frequency data streaming and algorithmic logic.

The Stack: It's a heavy infrastructure tool (around 300k lines of code) utilizing Docker, Redis, genetic algorithms for backtesting, and a built-in AI assistant to help wire up the visual nodes.

The Launch Drama:

I tried sharing the GitHub repo on Hacker News and Reddit earlier today to get some feedback from other engineers. The result? Instant shadowbans by auto-moderators. Because the engine handles financial data and algorithmic trading, bots immediately flagged the URL as spam.

So, I'm bringing it here. I know this community actually appreciates hard engineering, bootstrapping, and open-source infrastructure.

There is no paywall, no premium tiers, just pure code. I would genuinely love to hear what other builders think about the architecture.

I was frustrated by the state of algorithmic trading tools: you either have to build complex infrastructure from scratch, or rent expensive, closed-source SaaS "black boxes" where you don't own your data or logic.
