Beta Every check is free right now

Check it before you trust it.

Paste a package, a script or a website. We run it in a throwaway sandbox where it can't hurt anything, then an analyst tells you what it did and whether it's safe. Verdict first, evidence underneath.

“Is this site in good shape?”

Website health

A real browser visits the site from the sandbox and checks what people, regulators and AI assistants will see.

Experiments

Labs

Useful tools that don’t fit the “check it” story yet. Expect rough edges.

How it works

A lab and an analyst, for about a minute

  1. 01

    Paste it, or pick an agent

    A package name, a script, a URL. Plus your email so the report can find you.

  2. 02

    It runs in a sealed sandbox

    No access to your machine, your network or our secrets. Every file, process and connection is recorded.

  3. 03

    An analyst writes the verdict

    The AI reads the evidence and explains it in plain words: what happened, why it matters, what to do. Then the sandbox is destroyed.

Every report, same shape

Verdict first. Then why. Then the raw evidence.

Free scanners give you a log. We give you a decision you can act on, and keep the log underneath for when you want to check our work.

Why “micro environment”

The thing you're checking never touches you.

Every job gets its own sandbox that exists only while the agent works. Foreign code and files never touch anything else, and nothing lingers afterwards.

Read what we keep
Isolation
One sandbox per task. Foreign code and files touch nothing else.
Safety
Unknown scripts run where they can do no harm: no network, no secrets.
Privacy
The environment is wiped after the job; results are kept 7 days at most.
Predictable price
Every task has a time and step limit, so the cost per task is capped.
