AllSource vs mem0
mem0 is a memory layer that bolts onto your LLM app. AllSource is a durable event store underneath it — you keep full provenance and time-travel instead of a lossy summary.
| Capability | AllSource | mem0 |
|---|---|---|
Durable event store (survives restart) AllSource Core is the database: a Rust WAL (CRC32, fsync) with columnar Parquet persistence. Event data survives restarts. | WAL + Parquet | unknown |
Full event provenance / replay Every change is an immutable event you can replay to reconstruct any past state. | ||
Temporal / as_of queries Point-in-time projections are a first-class query, not a snapshot you have to manage yourself. | ||
Recall latency DashMap-backed in-memory reads over the durable log. Cloud memory APIs typically measure recall in tens of milliseconds. | 11.9μs (p99) | unknown |
Ingestion throughput Lock-free Rust core. We do not publish competitor throughput figures we cannot verify. | 469K events/sec | unknown |
Offline / embedded mode Run AllSource in-process as a library — no separate server or network hop required. | ||
MCP tools for AI agents A Model Context Protocol server ships out of the box for Claude and other MCP clients. | 43 tools | unknown |
x402 per-call agent payments Native x402 micropayments let agents pay per call instead of negotiating a seat-based contract. | ||
License / self-host Run the whole stack yourself for free, or use the hosted tiers. | MIT, self-host | MIT, self-host |
AllSource figures are from our own benchmarks and documentation. Cells marked “unknown” or “varies” are values we do not publish for mem0 rather than estimate. Based on public documentation; corrections welcome.
Pick AllSource if…
- You need every memory write to be auditable and replayable, not summarized away
- You want microsecond recall over a durable log, not a network round-trip to a memory API
- You want to embed the store in-process or self-host it for free under MIT
- Your agents pay per call (x402) instead of per seat
Pick mem0 if…
- You want a managed memory abstraction and are happy to self-host the open-source core
- You do not need full event provenance or point-in-time replay
- A higher-level 'remember this' API matters more to you than the underlying store
AllSource vs mem0: FAQ
Build on a durable event store
Start on the hosted Indie plan for $19/mo, or self-host the whole stack for free under MIT. Either way you keep full event provenance and microsecond recall.
