As answered by people managing React.run and Eventum.run.
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.
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.
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.
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.
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.
Eventum.run's answer:
Internal SIEM and data engineering teams at the author's Cyber Security company

It’s already been captured. Check out the docs for creating a new React app on react.dev: https://react.dev/learn/creating-a-react-app It throws you straight at Next.js. - Source: Hacker News / about 1 year ago
> The train of thought is “what is everyone using? I’ll use that too” I'm not so sure about that. We're seeing Next.js being pushed as the successor of create-react-app even in react.dev[1], which as a premise is kind of stupid. There is... - Source: Hacker News / about 1 year ago
The React documentation is infamously responsible of recommending Next as a "default". After a lot of backlash it got somewhat toned down, but it's still the first thing they suggest[1] for creating a new app [1]... - Source: Hacker News / about 1 year ago
