Eventum
Realistic synthetic events for testing, demos, and pipelines
Most tools generate random test data that looks fake the moment you inspect it. Eventum generates data that behaves like a real system: realistic timing, traffic that rises and falls, and events that follow each other like real user journeys. The result - demos that feel live, tests that catch real issues, and staging that looks like production, delivered anywhere in real time or in bulk. All from a simple config, no throwaway scripts.
Hi Product Hunt! I'm Nikita, the developer of Eventum.
I built it out of demo pain. I work on a data analytics platform similar to Splunk, and every customer demo needs a believable case: dashboards, searches and alerts running on data that looks alive. Real customer data is rarely an option, so we generated demo data. For years we used Splunk Eventgen, but for our workflow it never felt convenient - developing event samples was awkward, debugging took time, and running everything required extra effort. Every new demo turned into a small engineering project of its own.
Around 2023 I started building my own generator. The design goals came straight from that frustration: everything in plain YAML, a pipeline you assemble from swappable parts, and a web UI to preview and debug events before they go live - the part I missed most. At work it took off, and what began as a replacement for one internal tool grew into a full platform: many generators running in parallel, a REST API, an MCP server for AI agents, and ready-to-use content packs.
It's fully open source under Apache-2.0. Happy to hear what you think.
