Find Vulnerabilities
Before Attackers Do.
Managed AFL++, libFuzzer, Honggfuzz, and Centipede infrastructure for security teams. Deploy a full fuzzing campaign in minutes — no cluster setup, no DevOps overhead.
How It Works
Zero to Fuzzing in Minutes
No infrastructure to provision. No PhD required. Point Fuzze.rs at your target and let it find bugs.
Point to Your Binary
Provide a compiled binary via URL or the API. Supports any target compatible with AFL++ or libFuzzer — ELF, Mach-O, or custom harness.
We Handle the Infrastructure
Fuzze.rs provisions cloud instances, launches your fuzzer, and begins hammering your target immediately. No cluster to manage.
Crashes Delivered Instantly
Every crash is captured, de-duplicated, and sent to your dashboard in real-time with the reproducer input and triage info.
Platform Features
Enterprise Fuzzing. No Enterprise Overhead.
Everything your security team needs to run professional fuzzing campaigns — none of the operational burden.
Zero-Knowledge Architecture
Your binaries and source never touch our servers. Only crash data and execution metrics are transmitted — confidentiality by design.
Thousands of Execs/Second
AFL++, libFuzzer, Centipede, and Honggfuzz run on high-performance cloud instances optimized for maximum throughput, with each fuzzing job isolated in its own environment.
Instant Crash Reports
Real-time crash detection with automatic de-duplication. Crashes are categorized and delivered to your dashboard the moment they occur.
Full REST API
Programmatic control over every aspect of your fuzzing jobs. Start, stop, monitor, and retrieve results via our clean API or GitHub Action.
Live Coverage Metrics
Track code coverage, execution rate, and crash counts in real-time. Every job generates a detailed report for audit and compliance.
Flexible Compute Tiers
Pick the compute tier that fits your workload. Plans range from 8 cores for smaller targets up to 240+ cores for large-scale campaigns.
Power Fuzzing Mode
All Fuzzers. One Target.
Run AFL++, libFuzzer, Honggfuzz, and Centipede simultaneously against the same binary with a shared corpus. Each fuzzer's unique strengths compound — inputs that AFL finds seed libFuzzer, and vice versa — dramatically increasing coverage and crash discovery rates.
- Shared corpus — every fuzzer benefits from every discovery
- Per-fuzzer binary paths for custom instrumentation
- Unified dashboard — all child jobs in one view
- One API call starts the entire multi-fuzzer campaign
- Binary compatibility warnings surfaced before provisioning
