Application security for AI-built software

{{ line }}

AI-built apps ship with exposed databases and broken auth because the code works even when it isn't safe. Meshbound finds those holes, fixes them from a library of human-engineered remediations, and proves each fix worked before you approve it.

A plane needs a good pilot; a vibe-coded app needs an engineer behind it. Meshbound is that engineer, automated.

01 / the difference Everyone flags.
We fix, and we prove it.

Every other tool

A warning, and a prompt.

You are left trusting a language model to fix what a language model broke.

Meshbound

A fix, and the evidence.

Nothing is auto-applied. Nothing asks for blind trust.

03 / how it works A guardian, not an audit.

Connected once, it watches every push — because the next commit your AI writes can reopen the hole the last one closed.

the honest part

What we won't do

Some holes need a human decision — who should see this table, whether that endpoint should exist at all. When we hit one, we won't guess. You get a plain-language explanation, why it can't be fixed mechanically, and what the decision actually is.

4 / 5 of these are fixed and verified before you see them. The fifth changes how your app signs in, so we explain it and let you decide.

05 / pricing Cheaper than the audit. Faster than the breach.

Start with the free scan — it needs no signup and no access to anything. Connect a repository when you want the holes closed, not just listed.

Every plan reads your code to analyse it and does not retain it. Cancel whenever — the fixes you already merged are yours.

06 / questions The ones worth asking.

Anything we have not answered, ask us directly — a person replies.

07 / the front door

Point it at your live app. We'll show you what anyone can read.

No signup, no agent to install. Paste the URL of your deployed app and Meshbound runs the same first pass an attacker would — read-only, against your live endpoints. If a table is open, we show you a redacted row from it. Evidence, not a lecture.

Read-only. We never write to your app. Or see an example scan
