Questions & Answers

As answered by people managing Eventum.run and Buffer.

Which are the primary technologies used for building your product?

Eventum.run's answer

Python (FastAPI, Pydantic, Jinja2) for the engine, CLI and REST API; React + TypeScript for the Eventum Studio web UI. Ships as a pip package and Docker image.

Why should a person choose your product over its competitors?

Eventum.run's answer

Libraries like Faker give you fake values - Eventum gives you the whole pipeline: scheduling, templating, state, and parallel delivery to ClickHouse, OpenSearch, Kafka, files or any HTTP endpoint. And it ships with Eventum Studio, a web UI where you preview and debug events before anything goes live.

What makes your product unique?

Eventum.run's answer

Most data generators produce random values at a flat rate. Eventum also models behavior: traffic follows cron schedules, intervals or statistical time patterns with peaks, bursts and quiet periods, and templates persist state between events - three scopes of state plus a finite state machine mode for multi-step scenarios like user sessions.

How would you describe the primary audience of your product?

Eventum.run's answer

Data engineers, SIEM and detection engineers, and developers who need realistic data for testing pipelines, live demos, seeding databases or load testing - teams that would otherwise write throwaway generator scripts.

What's the story behind your product?

Eventum.run's answer

The author works on a data analytics platform similar to Splunk, where every customer demo needs a believable case running on data that looks alive. The team generated demo data with Splunk Eventgen, but the workflow never felt convenient, so around 2023 he started building his own generator. It grew into Eventum, now used by his SIEM team and data engineers daily.

Who are some of the biggest customers of your product?

Eventum.run's answer

Internal SIEM and data engineering teams at the author's Cyber Security company
