Delete dead code.
Keep tests green.
YAGNI connects to your repository like a careful senior engineer: it follows dead paths, removes unused modules, and opens pull requests only when every test still passes.
Dead code becomes a real problem
It adds up: slower builds, harder onboarding, and riskier refactors. Each path left behind makes the code you need tougher to change.
Connect today, merge a PR in hours
YAGNI links to your repository, observes runtime behavior, builds a production call graph, and submits a reviewed pull request your team can merge.
Connect your repo
Link a GitHub or GitLab repository. YAGNI reads its dependency graph and uses static analysis to surface possible dead paths within minutes.
Trace live call paths
A lightweight SDK observes staging or production. YAGNI records executed paths and compares them with the static graph.
Review, then merge
YAGNI opens a pull request explaining each removal, with tests passing and a confidence score for every candidate. Your team chooses what ships.
For codebases static analysis alone cannot explain
Linters report what code says. YAGNI observes what it does, pairing runtime traces with call graph analysis for greater confidence.
Trace the production call graph
Instrument your runtime to map live calls, including dynamic dispatch, reflection, and conditional imports that static analysis can miss.
Gate every PR for safety
YAGNI submits a removal PR only after existing tests pass, coverage thresholds hold, and each confidence score meets your configured threshold.
PRs your team can understand
Each PR explains in plain English why a path was marked dead, which signals confirmed it, and how long it has been inactive.
Small batches by default
Set the blast radius and remove code incrementally. A 500-line change is reviewable; a 50,000-line change is not.
Control the observation window
Choose how long a path must be observed before it becomes a candidate. Seasonal code, flags, and rare paths stay protected.
Fits your stack
Supports TypeScript, Python, Go, and Java. Connects with GitHub and GitLab, then runs in CI or on a schedule.
What early-access teams report
We began with a small set of engineering teams willing to connect their production repositories.
We connected YAGNI to our main service on Friday. By Monday morning, it had opened a PR removing 3,200 lines untouched since the product's first major pivot. Every test was green, the reasoning was clear, and we merged within an hour.
After three rounds of YAGNI removals, onboarding time dropped noticeably. New engineers stopped asking about paths that went nowhere. At last, the codebase matched the architecture diagram.
