Trusted by devs shipping to production
“Being able to test before production is huge. Zeeroday runs the app in a private sandbox, lets agents attack it, and gives me evidence I can actually act on before launch.”
@sandbox-fndr
“Zeeroday makes security visible. I can watch agents use the app, test edge cases, and surface exploit paths that would be easy to miss during normal launch prep.”
@ship-labs
“The browser-based swarm is the difference. It does not feel like a chatbot reviewing code — it feels like a controlled attack session against a real running app.”
@frontend-pilot
“The best part is seeing every step live. Login attempts, route changes, API probes, permission checks — it feels like watching a real attack, but safely.”

@mamuli23
“The sandbox makes the product feel safe. I can let agents attack aggressively without touching production data or real users.”
@andro-rc
“Zeeroday helped me think beyond the happy path. My app worked fine, but the swarm showed where a user could push the flow further than intended.”
@free-dev
"Zeeroday closes the loop nicely: find the exploit, understand the attack path, generate a patch, and rerun the same flow to verify the issue is gone.”
@xpahmad

“This is much clearer than asking an AI to review code. Zeeroday runs the app in a sandbox and lets agents behave like real attackers.”
@the-yankeys
“I like that Zeeroday can test a private copy before the app is public. It gives me a way to find dangerous issues before users, search engines, or attackers ever touch the app.”
@site-studios
“The live attack trace is what makes it useful. Instead of getting a vague warning, I can see what the agent tried, where it went, and why the issue matters.”
@pristasmo
“Zeeroday feels different from a scanner because you can actually watch the agents move through the app. They click, type, log in, change routes, and show the exact moment something becomes exploitable.”

Got questions?
We’ve got answers.
01
Does Zeeroday attack my production app?
No. Zeeroday runs attacks against a private sandbox copy of your app. The swarm uses test credentials, controlled environment variables, and an isolated runtime, so real users and production data are not touched.
02
Can I hack my app before it is live?
Yes. Zeeroday can run your app from a GitHub branch, preview build, or setup command inside a sandbox. This lets you find exploitable auth, API, payment, and permission issues before your app is public.
03
Is Zeeroday just an AI code scanner?
No. Zeeroday does not just read code and generate suggestions. It runs your app, gives agents a real browser, and lets them click, type, log in, change routes, submit forms, probe APIs, and record what actually happens.
04
What does an attack swarm actually do?
Attack swarms test the hostile paths normal QA usually misses. Agents try to bypass login, access other users’ data, unlock paid features, abuse API endpoints, inject bad inputs, trigger errors, and find hidden routes.
05
What do I get after a swarm run?
You get exploit reports with the affected route, severity, attack path, screenshots or logs, reproduction steps, impact explanation, and suggested fix. The report is based on observed agent behavior, not vague scanner warnings.
06
Can Zeeroday help me fix the exploit?
Yes. For confirmed exploits, Zeeroday can generate a targeted patch, show you the diff, apply the fix, and rerun the same attack path to verify that the vulnerability is blocked.
