The Problem
Applications often coordinate data across several sources. This adds logic, creates inconsistencies, makes applications run hot, and makes them harder to scale.
Data duplication and inconsistency lead to the inability to access and use potentially invaluable data. This can result in missed opportunities, wasted resources, and lost revenue.
The real problem is that data is not treated as a first-class citizen.
The Solution
Stardust is an append-only temporal data engine that uses web standards. Its API gives humans and LLMs access to the same source of truth.
This results in applications that are lean, fast, and highly scalable, with the same or more capabilities as traditional apps. Streaming backups are built-in, and data is immutable.
As an append-only temporal data store, history is queryable and data becomes fully explorable over time.
One data store to rule them all.
Stardust replaces fragmented data sources with a single source of truth, ensuring data integrity and consistency across your applications.
History is immutable & queryable.
Stardust is an immutable, append-only data store. It maintains a complete history of all data changes, allowing you to query past states and understand how your data has evolved over time.
Made for humans and LLMs.
Stardust is designed to be used by both humans and LLMs, providing a simple and intuitive user interface for exploring and manipulating data, and an API that any LLM can interact with.
Self-host in cloud or on-premise.
Stardust is a single binary that you can run on almost any hardware. Self-host it in a cloud server or on-premise. Your data remains yours. To increase capacity, just add disk space.
Schema can evolve.
Stardust allows your data to change shape over time, without having to write migrations. Schemas allow you to project and validate your data, while remaining independent of the data itself.
Built-in streaming backups.
Stardust streams transactions to S3-compatible object storage or network-attached storage (NAS). Set it up once and never have to think about backing up your data again.

Delaney Gillilan
Lead Architect & Engineer
“I have spent my career with systems where incorrect data can cause real-world harm. These systems must record who changed what, when, and why.
At production scale, that record often becomes expensive, slow, and difficult to trust. Teams then must select between delivery speed and complete history.
Stardust is the most important work of my career. It lets teams focus on unique project knowledge without losing information.
Its design comes from at least a decade of experiments with entity-component-system ideas for databases. Many approaches failed, and those failures shaped the current design.”
Ben Croker
Head of Product & Strategy
“Almost every application I have worked with has had a bottleneck that could bring it to a grinding halt as it scales.
Performance at scale is one of the hardest problems I’ve encountered in twenty-five years of real-world application development.
Stardust is the first solution I am aware of that tackles this problem head on. As a data engine, it can handle business logic that applications traditionally manage.
This opens the door to applications that scale massively while remaining fully auditable and time-travelable.”
