Who We Are & What We Build
PulseSocketDB is an open-source, self-hosted real-time database engine (BaaS) that separates the Control Plane from the Data Plane, ensuring 100% data sovereignty.
Our Pioneering Mission
PulseSocketDB pioneered a revolutionary paradigm shift in Backend-as-a-Service (BaaS): separating the Control Plane from the Data Plane. While cloud giants lock your data inside proprietary environments and bill you for every single read and write operation, PulseSocketDB manages the Control Plane intelligence while keeping 100% of your production data on your own VPS.
We empower developers and businesses with sub-millisecond real-time sync, full compliance with strict data sovereignty laws (LGPD/GDPR), and absolute financial predictability without vendor lock-in.
Why We Are Unique
- Pioneering Control Plane SaaSWe manage API keys, security rules, usage metrics, and billing. Your data stays 100% on your own VPS Redis instance.
- LGPD & GDPR Native SovereigntyZero third-party data telemetry. Complete physical and legal custody over user information by design.
- Predictable Pricing (No Billing Shocks)No per-operation read/write fees. Fixed monthly subscription for Control Plane capacity.
The Sub-ms Synchronization Lifecycle
Trace the journey of a data change from a client update to local VPS persistence and room broadcast.
1. Client Mutation
A user triggers an update or action on your frontend app, mutating a document key or value instantly.
// Client SDK update
db.collection('messages')
.doc('msg-101')
.update({
text: 'Hello!'
});2. WebSocket Uplink
The Client SDK transmits the mutation event over persistent Socket.io WebSocket connections in sub-milliseconds.
// WebSocket Event Packet
[EMIT] -> write_event
room: "messages:msg-101"
data: {
text: "Hello!"
}3. Control Plane Auth
The PulseSocketDB SaaS engine authenticates the API key and checks user-defined security and permission rules.
// Auth & Rule Checker
IF request.apiKey === OK
AND rules.write(auth, data) === TRUE
THEN allow_write = true;4. Physical VPS Write
The authorized write is committed directly to your private Redis instance on your own VPS. Complete data custody.
// VPS Redis Hash Commit
redis.hset(
"messages:msg-101",
"text", "Hello!"
);5. Pub/Sub Broadcast
Redis Pub/Sub propagates the change across broker nodes, instantly emitting the mutation to all socket room subscribers.
// Real-Time Broadcast
redis.publish("messages:msg-101")
-> emit_to_room("messages:msg-101")
-> view.update()Engine Architecture Flow
