What we believe

We build the product on three principles, and each one has a concrete counterpart in it.

  1. Architecture sits above code quality.

    Linters are great but not enough. The long-term health of a codebase is decided between modules and layers, not inside files.

    In the productLayer and dependency rules, and an architecture map of how modules connect.

  2. Rules belong in the code, not in a document.

    A rule that sits in a wiki is rarely applied. An effective rule shows up on every PR, explains its reasoning and can be overridden when it is wrong.

    In the productRules are managed per project in the panel. Every comment carries the rule's explanation, a suggestion and a link to the rule's page; a finding is closed one at a time, with a reason.

  3. Engineers deserve a tool they can trust, not fear.

    False positives erode trust in a tool; a tool that never speaks up is no use either. The right balance: few but accurate signals, in plain language.

    In the productRules are narrowed by looking at their results on real code bases, and comments are written in the language each workspace chooses.

How it started

Was there a reason behind this code decision, or did nobody notice for six months?

Building our own SaaS, we kept hitting the same questions: "Was there a reason behind this code decision, or did nobody notice for six months?" Review notes got forgotten, wiki rules died on arrival. Linters stayed at file level, never touched the relationships between modules.

In early 2026 we wrote an internal prototype that enforced a single rule - "domain must not depend on framework". In three weeks it caught 14 violations - each one either real bug or real conversation. That was the moment we decided: this can't stay internal.

Today, from Istanbul, we're building the strictest architectural control tool for polyglot codebases. We're not growing a company - we're building a tool meant to last.
