Memory blocks
The unit of shared state. Each block holds a piece of your app's memory and can grow with your product.
A new kind of app backend
Own your app's memory.
Share it on your terms.
MemoBlocks is a user-extensible backend where data models can evolve in the open. Explore, adapt, and connect app memory without giving up control.
Why MemoBlocks
Most apps let people create content, but not shape the structure behind it. MemoBlocks treats structure and content as part of the same living system.
- Inspect how your data is organized.
- Extend existing models safely.
- Connect apps through shared memory, not glue code.
How it works
Living schemas
Schemas are first-class. They evolve in the open, in version, alongside the data they describe.
One MemoSpace
Blocks and schemas come together as a MemoSpace — your app's memory, ready to be replicated, shared, or extended.
Built for real product teams
Ship fast, stay flexible
Start simple, then grow your data model without painful resets or migration freezes.
User-driven extensibility
Power users and admins can evolve structures with tools — not migrations by ticket.
Integrations as shared memory
Connect systems by exchanging data blocks directly, instead of stitching endless API adapters.
Agent-ready by design
A memory layer agents can actually use
MemoBlocks gives AI assistants a stable, inspectable memory layer they can read, extend, and reason about safely. Humans stay in control while agents help with structure, cleanup, and cross-app workflows.
A better backend relationship
MemoBlocks is for teams that want backend power and user agency.
Not "database as black box."
Not "integration as glue code forever."
More like a shared memory layer your product can grow with.
Built on Hyper Hyper Space
MemoBlocks is powered by Hyper Hyper Space v3, a data sync engine designed for decentralized authority and verifiable, peer-to-peer collaboration.
We focus on the product experience. HHS handles the hard parts of secure, coordination-free synchronization underneath.
Get early access
If your product's data model keeps changing, MemoBlocks is built for that reality.
