IP Stresser & Free Stresser — DDoS Platform
Deploy our IP stresser to benchmark infrastructure against real-world DDoS patterns. Includes a fully functional free stresser tier — no registration required for basic tests.
IP Stresser — Enterprise Network Diagnostics
Our IP stresser is a hardware-accelerated traffic generation engine designed for authorized resilience validation. Unlike uncontrolled DDoS tools, the stresser enforces token-based authorization, rate caps, and full audit logging. Use the IP stresser to simulate volumetric floods, protocol exhaustion, and application-layer saturation against your own infrastructure.
IP Stresser SYN Flood
TCP handshake exhaustion at \( 2.4 \times 10^6 \) packets/sec. Spoofed source IPs with custom window scaling. The IP stresser maintains 850k concurrent half-open connections.
IP Stresser HTTP Flood
Recursive GET/POST with dynamic UA rotation. The stresser engine bypasses basic CDN caching through query parameter randomization at \( 1.8 \times 10^5 \) req/s.
Free Stresser — Zero-Cost Network Validation
The free stresser tier provides immediate access to basic DDoS simulation vectors without payment or commitment. Each free stresser session is capped at 1.5 Gbps and 300 seconds, making it ideal for quick firewall rule verification. Upgrade to the full IP stresser for unlimited concurrency and advanced vector scripting.
Free Stresser Basic
3 tests/day · 1.5 Gbps cap · SYN + UDP only. The free stresser basic plan requires only email verification.
Free Stresser Pro Trial
10 tests/day · 5 Gbps cap · Includes HTTP Layer 7. Experience the full stresser capability for 7 days.
IP Stresser Unlimited
No caps · API access · Custom scripts · 95 Gbps burst. The premium IP stresser for enterprise security teams.
DDoS Simulation for Defensive Readiness
A DDoS (Distributed Denial-of-Service) attack overwhelms target resources with malicious traffic. Our platform repurposes DDoS techniques as controlled simulations. Using the IP stresser or free stresser, security engineers replicate volumetric DDoS, protocol DDoS, and application-layer DDoS patterns to validate mitigation strategies.
DDoS UDP Amplification
Reflection-based DDoS using CLDAP (factor 56×), NTP (factor 48×), and Memcached (factor 9,000×). Our stresser replicates these DDoS vectors with precise bps throttling.
DDoS SYN-ACK Reflection
Protocol-level DDoS exploiting TCP state machine asymmetry. The IP stresser generates spoofed SYN packets triggering amplified SYN-ACK responses toward the target.
DDoS Slowloris Variant
Application-layer DDoS holding connections open with partial HTTP headers. Tests timeout configurations and connection pool limits.
DDoS Carpet Bombing
Combined DDoS strategy spreading traffic across IP ranges to evade volumetric thresholds. The stresser orchestrates up to 12 concurrent vectors.
Stresser Methods & Attack Vectors
Every stresser method maps to a real-world DDoS technique.
The IP stresser exposes these via REST API (0x7F3A) with
granular parameters for packet size, rate, duration, and source IP spoofing mode.
Stresser SYN Flood
Flags: 0x02 (SYN). Rate: 2.4 Mpps/core. Window size: 65535. The most common stresser vector for firewall testing.
Stresser UDP Flood
Payload: random 1024–1472 bytes. Rate: 3.1 Mpps/core. Efficient for testing rate-limiting and QoS policies.
Stresser ICMP Flood
Type 8 (Echo Request). Rate: 1.8 Mpps. Useful for validating ICMP throttling and kernel network stack resilience.
Stresser GET Flood
Recursive paths, randomized query strings. The free stresser includes this at reduced rate (500 req/s).
Stresser POST Flood
Form data submission with large payloads. Tests application server thread pools and database connection limits.
Stresser DNS Amp
ANY queries to open resolvers. Amplification factor: 28×–54×. The IP stresser supports EDNS0 for maximum payload.

Frequently Asked Questions
How does the free stresser differ from the IP stresser?
The free stresser offers 3 daily tests at 1.5 Gbps with basic vectors. The premium IP stresser unlocks unlimited tests, 95 Gbps throughput, custom scripting, and API access. Both tools simulate DDoS patterns under authorization.
Is DDoS testing legal with this stresser?
Yes, when targeting infrastructure you own or have explicit written authorization to test. Our IP stresser enforces token-based consent and maintains full audit trails. Unauthorized DDoS is illegal; our stresser is a defensive tool.
Which stresser method is best for testing a CDN?
The HTTP GET Flood in our IP stresser uses recursive path generation and dynamic query strings to bypass edge caching. Combine with the free stresser UDP flood for transport-layer validation.
Can the free stresser simulate a real DDoS botnet?
The free stresser uses a single geographic PoP. For multi-origin botnet simulation with 12+ vectors, upgrade to the full IP stresser with geo-distributed agents.
