Developer Tools for the AI Era

zaks.io

Software that makes AI visible.

We build developer tools that show you exactly what your AI is doing — and what it's costing you.

Products

Trace Flow

Live

See what your AI is actually costing you.

Your AI spend is a black box. You're shipping features using GPT-5, Claude, Gemini — but you have no idea what each call actually costs or how long it takes.

Trace Flow is a streaming proxy that sits between your app and your LLM providers. Change one base URL and get full visibility — costs, latency, and token usage across every provider.

  • Zero added latency

    Streaming proxy architecture means your requests are never slowed down.

  • Multi-provider support

    OpenAI, Anthropic, Google, and more — all in one dashboard.

  • Drop-in proxy, no SDK

    Change one base URL. No code changes, no vendor lock-in.

  • Cost & usage dashboard

    Real-time visibility into spend, token usage, and latency per model.

About

Built by Isaac Suttell

10 years building mission-critical infrastructure at PlayStation Studios. Every first-party AAA game shipped with my code. I was the one on call at 3am when a studio was in crunch and the tools went down.

I left to test a thesis: one engineer, augmented by AI, can build and ship software that rivals what large teams produce.

Zaks.io is that experiment. Bootstrapped. San Diego. No outside funding. Just good software.
