Stream realistic mock data with a click.

Building software that connects to physical devices and data-emitting systems is challenging. Overseed speeds up engineering cycles and enables teams to work in parallel by simulating hardware and APIs. Now anyone can generate realtime mock data that is realistic and configurable.

Enable parallel work

Reduce dependencies and eliminate blockers between hardware, software and data science teams. Whether it's a third-party integration or your own hardware or firmware team, Overseed lets various teams determine data interfaces quickly and work in parallel.

Flesh out edge-cases

Working with realistic mock data early in the development process helps teams clarify product requirements and surface edge cases. With Overseed it's easy to collaborate on the attributes and behavior of an API and simulate a variety of UX/UI states.

Run realistic demos

Realistic data helps business users understand features and tell compelling stories. Unfortunately it takes real work to create one-off demo environments that "just work" with legitimate data. Create multiple data streams and let users switch between a variety of scenarios to showcase real situations.

How it works

Define the schema & shape of your data

Use JSON to specify the attributes, data types, and structure of your data. Use preset data types like credit card numbers and IP addresses, or create a custom attribute like "chlorineLevel" (or whatever your gadget does!).

Schemas also define the range of possible values and distribution of data. In other words, you can specify that the "volume" attribute is an integer between 0 and 100, and 80% time it falls between 45 and 75.

Generate data streams and files with a click

Generators are the engines that power your synthetic data. Simply choose a schema & version, then specify the frequency that records should be created. Overseed automatically stands up an API endpoint and emits data according to your spec. Or you can create a flat file with any number of records.

Collaborate & work in parallel

Generators are the engine that power mock data. Simply choose a schema & version, then specify the frequency that records should be created. Overseed automatically stands up an API endpoint and emits data according to your spec. Or you can create a flat file with any number of records.

Switch to live data when you're ready

Generators are the engine that power mock data. Simply choose a schema & version, then specify the frequency that records should be created. Overseed automatically stands up an API endpoint and emits data according to your spec. Or you can create a flat file with any number of records.
