Built by developers, for developers
ArchSetu started as a VS Code extension to help developers navigate large, unfamiliar codebases. Understanding architecture should not require reading ten thousand lines of code. So we built the tool we always wished existed.
The story
Every developer has faced this: you join a new team, inherit a legacy codebase, or want to contribute to an open-source project. The first question is always the same: where do I even start?
We spent years watching developers burn hours on this problem. Reading file by file. Running grep sessions. Asking senior engineers who themselves were guessing. The mental model of how code connects is almost never documented, because it changes every sprint.
ArchSetu solves this with pure static analysis. We parse code the same way a compiler does, by reading structure rather than executing logic. No AI interpreting things, no cloud model guessing at what your function does. Just the actual call graph, dead code, and complexity score.
We built ArchSetu in India, because Indian engineering teams face this problem acutely. Massive legacy codebases, fast-growing startups with minimal documentation, and remote teams that cannot rely on hallway conversations to share architecture knowledge.
Why this matters more now, not less
AI writes code faster than any team can review it
A growing share of the code in any real codebase was generated by an assistant, not written and remembered by a person. That is not a problem AI review tools can fully solve either - asking one language model to grade code another language model wrote is still a guess, just a more expensive one. Architecture understanding has to come from the code itself, computed the same way every time. That is the actual gap ArchSetu is built to close, and it gets more relevant every quarter code generation accelerates, not less.
A real parser per language, not one regex pretending to understand 47 of them
Every supported language gets its own syntax-tree parser, built to that language's actual grammar. A Python decorator and a Go struct tag are not the same shape - ArchSetu never treats them like they are.
A real call graph, traced, not guessed
Every function, every caller, every import resolved from the syntax tree - the same structural information a compiler needs, not a language model's best guess at what a function "probably" does based on its name.
The same repo produces the same report, every time
No sampling, no temperature, no "run it twice, get two different answers." A health score computed today is the same score computed next week on the same commit - you can build a CI gate on top of that. You cannot build one on an LLM's mood.
Security findings, disclosed responsibly by design
A finding's exact file and line is only ever shown to that repository's verified owner, or the account that submitted a private analysis. Everyone else sees a severity count, not a map of what to exploit. That is enforced in the product, not a policy on a page nobody reads.
Your source code is never retained
A repository is cloned into an isolated environment, analyzed, and the clone is deleted immediately after. There is no step in this pipeline where your code is used to train anything, sold, or kept around "just in case."
Not a demo
Run against real, working codebases, at real scale
These are live counts from ArchSetu's own database, the same query an engineer here would run to check the system, not a marketing estimate. Every number updates as more repositories get analyzed.

What we stand for
Static Analysis Only
No AI. No LLMs. No hallucinations. Every insight is derived from parsing your actual code structure.
Privacy by Design
We clone your repo, analyze it in an isolated container, then delete it immediately. We never store source code.
Speed Over Everything
Full repo analysis in under 60 seconds. Results are cached and shareable instantly.
Built for Teams
From solo developers to engineering teams enforcing architecture rules in CI. ArchSetu scales with you.
Proudly made in India
ArchSetu is designed, built, and maintained in India. We believe world-class developer tools can be built from India, for the world. Our infrastructure is hosted on global cloud providers to ensure speed everywhere, but our heart and team are in India.
