The industry-standard, fully headless load testing platform built to simulate real player behavior across gaming, blockchain, and high-concurrency enterprise systems.
No-commitment consultation
Proposal in 5 days
Trusted by 150+ studios
Trusted by Industry Leaders
Headless concurrency testing for multiplayer backends. We don't just "ping" your servers. We replicate the entire ecosystem of your game or platform.
No rendered game clients. No hardware bottlenecks. Just pure network-level concurrency simulation for accurate infrastructure testing.
Bots execute complete user flows including authentication, matchmaking, gameplay loops, store purchases, and Web3 transactions.
Cloud-deployable and horizontally scalable architecture. Test anything from 10K users for feature validation to millions for peak event modeling.
Direct integration with Unreal Engine, Unity, Photon, custom backends, TCP/UDP protocols, and proprietary networking stacks.
Swarm doesn't simulate "traffic." It simulates players and users.
Swarm powers all Cyrex load testing engagements - from stress testing to spike testing
Swarm is the proprietary technology behind every Cyrex load testing engagement - from baseline validation to peak event modeling.
Generic tools can't replicate multiplayer game traffic at scale
Tools like Selenium, Playwright, or Unity Test Framework spin up full game clients. This introduces rendering overhead, memory bloat, and artificial concurrency caps. You're not testing your backend — you're testing how many clients your test rig can render.
Generic HTTP flood tools (JMeter, Locust, K6) don't integrate with UDP-based game protocols, stateful sessions, or real-time multiplayer traffic. They can't replicate matchmaking, lobby systems, or client-authoritative flows.
Empty traffic doesn't replicate how real users behave. Authentication, matchmaking, gameplay state synchronization, inventory updates — these are the actions that break backends under load. You need to simulate actual player journeys.
Studios that skip load testing gamble with infrastructure stability.

Studios that skip load testing gamble with infrastructure stability. Pre-launch bottlenecks go undetected. Post-launch, those bottlenecks become outages.
Authentication queues break, matchmaking times out, and game states desync. When pre-launch bottlenecks remain hidden, they inevitably manifest as production failures that crash your service and frustrate players.
Launch windows are final; you cannot re-launch. In the modern live-service era, negative community sentiment spreads significantly faster than your engineering team can deploy fixes.
Swarm validates your infrastructure before the first player arrives. We turn performance testing from a high-stakes gamble into a structured, predictable, and controllable part of your release cycle.
Your backend will fail at scale. Test it before your players and users do.
Real-world concurrency testing for AAA and Web3 games
