Your AI agents keep re-inventing variables.
One session writes MAX_RETRIES; the next invents RETRY_LIMIT for the same idea — and the two drift apart. VarAlign remembers what your agents named things, across sessions and across Claude Code and Kilo, and shows you every duplicate and drift.
Free extension · deterministic (no LLM) · 100% local — your code never leaves your machine
AI Code Alignment Audit
We run VarAlign across your codebase, triage every finding with notes, separate real issues from intentional differences, and deliver a prioritized report with a remediation path. Fixed fee, $1,500–$5,000 per repository by size — and every audit doubles as your team's onboarding to the tool.
The problem is measured, not hypothetical
Independent research keeps finding the same thing: AI-assisted codebases accumulate duplication and naming inconsistency faster than teams consolidate it.

See it in action
A real capture, not a mockup: detect the duplicates, review a pair, dismiss an intentional one — the whole naming family quiets — and generate a remediation prompt for your AI assistant.
How VarAlign works
A memory your agents don't have
A capture hook records every assignment your AI assistant writes — name, value shape, file, session — into a plain-file registry inside your repo. A baseline scan covers pre-existing code, and the next session starts with a 'these names already exist' context block.
Language-aware duplicate scoring
A deterministic engine scores duplicate, drifted, and misaligned suspects. It knows Python constant casing, Go export capitalization, and PowerShell case-insensitivity — so conventions don't get flagged, and real collisions do.
You stay the judge
Native VS Code views show every suspect: dismiss (one dismissal quiets the whole naming family), confirm, hand a fix prompt to Claude or Kilo — or let Pro's Merge Variables consolidate the pair in one step. A CI gate can hold the line in pipelines.
Your code never leaves your machine
The engine ships inside the extension and runs on your hardware. No cloud analysis, no telemetry, no account — and no LLM: detection is deterministic, so results are reproducible and free. Even the Pro license is verified offline. If you work in a locked-down or air-gapped environment, VarAlign was built for you.

VarAlign Control Tower
The extension works one repository at a time. Control Tower is the fleet view: point it at a folder and it finds every repository underneath that has a .varmem store, imports them all into one database, and shows the whole set side by side — what drifted, what vanished, what you already reviewed.
- Recursive scan finds every repository with a .varmem store under a folder you pick, nested ones included, in one pass
- Per-repository status counts plus a drill-down grid of every tracked variable, filterable by status, language, or free-text search
- Analytics over the imported set: status and origin breakdowns, per-language distribution, 30-day activity, and the files carrying the most drift
- Imports land in a local SQLite database on your own PC — no account, no cloud service, no telemetry
- Optionally mirrors to a PostgreSQL server you supply, so several workstations can feed one shared store — off by default, password encrypted with Windows DPAPI
- Read-only toward your repositories: it never writes into a .varmem folder
Requires the free VarAlign engine. Control Tower reads .varmem registries — it does not create them. Install the engine and its capture plugin first; Control Tower is the fleet view on top.
Available now on the Microsoft Store
Team and Enterprise deployment — shared PostgreSQL infrastructure, centralized configuration, organizational rollout and support — is a separate offering from Green Yoga Inc and is not included in the individual purchase.
Frequently asked questions
- What is VarAlign?
- VarAlign is a VS Code extension plus a zero-dependency engine that tracks every variable assignment AI coding agents write in your repositories, across sessions. It detects duplicate concepts (MAX_RETRIES vs RETRY_LIMIT), values that drifted apart, and misaligned naming — and gives you a review workflow to dismiss, confirm, or fix each finding.
- Does my code leave my machine?
- No. Detection, scoring, and storage all run locally — the engine ships inside the extension, there is no cloud analysis, no telemetry, and no code upload. The analysis is deterministic (no LLM involved), so it also works in locked-down and air-gapped environments.
- Which AI coding tools does it work with?
- VarAlign installs a capture hook for Claude Code today, with a Kilo Code adapter in progress — both agents share one per-repo registry. It also works with any workflow via a full-repo baseline scan, so you can use it even without a supported agent hook.
- How is it different from a linter or PR review bot?
- Linters and PR bots see one file or one diff at a time. VarAlign's findings come from a persistent cross-session registry, so it catches the inconsistency that only exists across sessions and across agents — the exact class of problem diff-scoped tools miss. Its language-aware engine knows Python constant casing, Go export capitalization, and PowerShell case-insensitivity, so conventions are not flagged as duplicates.
- What does Pro add, and how does the license work?
- Pro ($79 per year, one seat) unlocks Merge Variables — pick a duplicate pair and VarAlign consolidates it: canonical name, references rewritten, duplicate definition removed. The license is an offline Ed25519-signed key delivered by email: paste it into VS Code with the 'VarAlign: Enter License' command. Verification happens on your machine with a 14-day grace period past expiry — no account, no phone-home.
- What is VarAlign Control Tower?
- Control Tower is a companion Windows desktop app. The VS Code extension works inside one repository; Control Tower is the fleet view across all of them. Point it at a folder and it finds every repository underneath that has a .varmem store — nested ones included — imports them into one local SQLite database, and shows per-repository status counts, a filterable grid of every tracked variable, and analytics across the whole imported set: status and origin breakdowns, per-language distribution, 30-day activity, and the files carrying the most drift. It is read-only toward your repositories and never writes into a .varmem folder.
- How much is Control Tower, and where do I get it?
- US$19.99 as a one-time purchase for one individual, with a 7-day free trial at full functionality. It is available now on the Microsoft Store. It requires the free VarAlign engine, which writes the .varmem registries it reads; Control Tower does not create them. Everything it imports stays on your own PC, with no account and no telemetry; mirroring to a PostgreSQL server you supply is optional and off by default. Team and Enterprise deployment is a separate offering and is not included in the individual purchase.
- What is the AI Code Alignment Audit?
- A fixed-fee engagement ($1,500–$5,000 per repository, by size) where we run VarAlign across your codebase, triage every finding with notes, separate real issues from intentional differences, and deliver a prioritized report with a remediation path. It is the fastest way to know where naming and configuration drift are accumulating in an AI-heavy codebase.
- Is VarAlign open source?
- The engine is Apache-2.0 (free forever, the adoption core). The VS Code extension is source-available under the Business Source License 1.1 — free to use and modify, no reselling or competing hosted offering, converting to Apache-2.0 in 2030. The extension source is public on GitHub.
