Built for teams using more than one AI coding agent

Your AI coding agents need one project brain.

Claude Code, Cursor, Codex and other coding agents can each make sensible decisions — and still pull the same repository in different directions. CrossCheck gives the repo one shared decision boundary.

The disagreement stops here.

You decide the architecture once. The next agent gets the same boundary instead of guessing.

The hidden cost of multi-agent coding

Nothing has to look broken for the repo to be drifting.

One agent keeps Prisma. Another introduces Drizzle. One assumes Clerk. Another builds Auth.js. The code can look fine for hours before the contradiction finally becomes visible.

01

Agents choose independently

Each coding agent works from the context it can see. They do not automatically inherit every architectural decision another tool made.

02

The conflict hides in plain sight

Both changes can look reasonable on their own, so the disagreement often survives until tests, review or a later feature exposes it.

03

You pay in rework

The time AI was meant to save gets spent undoing code, fixing integrations and deciding which direction the repository was meant to follow.

Proof before payment

Test the idea on your own repo first.

Choose a repository folder in the browser or run the local scanner. CrossCheck currently checks supported conflicts around database engine, ORM, authentication provider and package manager.

Local

Your scan runs against files on your machine.

Private

No source-code upload to zFinia.

Immediate

See the supported conflict result before deciding to subscribe.

Fastest way to try CrossCheck

Scan a repo folder in your browser.

Pick the repository folder. CrossCheck reads only its supported config and decision files in this browser tab. Your files are not uploaded.

The scan itself stays local. Standard zFinia page analytics record only that a browser scan ran and a bounded outcome such as conflict count/classes — never repository contents, file paths or source code.

Prefer the terminal?

Run the same supported free check from the repository root:

macOS / Linux — run from the repository root
curl -fsSL https://www.zfinia.com/crosscheck-free.mjs -o crosscheck-free.mjs && node crosscheck-free.mjs --source direct
Windows PowerShell — run from the repository root
iwr https://www.zfinia.com/crosscheck-free.mjs -OutFile crosscheck-free.mjs; node .\crosscheck-free.mjs --source direct

Your source code stays local. This command downloads the public scanner and sends small anonymous usage events: scanner version, OS/Node family and bounded scan outcome. No repository contents, paths or source code are sent. Add --no-telemetry or set ZFINIA_TELEMETRY=0 to opt out. A random temporary ID helps estimate repeat use until your system clears it.

For a fully offline scan after download, run node crosscheck-scan.mjs directly. Native guards, Git checks and MCP remain offline.

What US$29/month actually buys

A durable decision layer around the repository.

CrossCheck is not just a one-time scanner. The paid product keeps supported project decisions with the repo and checks future agent work against the same boundary.

✓

Persistent decisions

Pin supported choices in a repo-level decision contract so the next agent sees the same canonical direction.

✓

Pre-write + post-edit checks

Documented agent adapters check recognized changes close to the moment a conflicting assumption turns into code.

✓

Git + CI backstops

Shared repository boundaries remain in place even when the editor or AI agent changes.

✓

Controlled migrations

Intentional architecture changes can move through a migration path instead of forcing the guard off.

✓

Receipts + local history

Supported blocked conflicts get local evidence so you can see what was stopped and why.

✓

Protection diagnostics

Status and protection checks make it easier to know whether the guardrail is actually active.

Questions developers ask before trusting a guardrail

Know exactly what you are installing.

What problem does zFinia CrossCheck solve?

CrossCheck helps a repository keep one supported set of project decisions when multiple AI coding agents are working on it. It can catch supported contradictions such as PostgreSQL versus MySQL, Prisma versus Drizzle, Clerk versus Auth.js, and package-manager conflicts before they become rework.

Does CrossCheck upload my source code?

The free browser and local scans run against your repository without uploading your source code to zFinia.

Which AI coding tools does CrossCheck support?

The current product documents native adapters for Claude Code, OpenAI Codex, Cursor, GitHub Copilot through VS Code hooks in Preview, Gemini CLI, Windsurf/Cascade, and Cline, with Git and CI as shared repository boundaries. Exact setup and platform limits are documented on the compatibility page.

What does the US$29 subscription add?

The paid product adds a persistent supported decision contract, agent checks, Git protection, controlled migrations, local conflict receipts and history, plus status and protection diagnostics for one repository.

One repo. One set of supported decisions.
