Show HN: Unisondb A open source streaming multimodal database for Edge Computing

Hi everyone — I’m the developer of UnisonDB, an open-source log-native database built in Go for distributed and edge-scale systems.

UnisonDB rethinks the boundary between databases and streaming systems. Instead of treating the Write-Ahead Log (WAL) as a recovery mechanism, it treats the log itself as the database. Every write is immediately durable, queryable, and replicable — without Kafka, CDC pipelines, or changefeed daemons.

UnisonDB unifies persistence and streaming in one system.

It’s designed for real-time, event-driven, and edge-first workloads where data needs to move as fast as it’s written.

Key features:

1. Multi-Modal Storage: Key-Value, Wide-Column, and Large Objects (LOB)

2. Streaming Replication: WAL-based replication with sub-second fan-out to 100+ edge replicas

3. Edge-First Design: Optimized for edge computing and local-first architectures

4. Namespace Isolation: Multi-tenancy support with namespace-based isolation

Feedback, testing, or contributions are all welcome
