SELF-HOSTED AI MEMORY · AVAILABLE NOW
Self-Hosted AI Memory across Japan
Self-hosting should be production-ready, not a tarball. MemHub ships RLS, restricted roles, audit trails and pg_dump backups — compliant from day one, no external API.
Data residency answered in one line: ‘your datacenter.’ Run in-region, keep embeddings local via Ollama, pass the DPO review without drama. Free to self-host.

Definition
What is Self-Hosted AI Memory across Japan?
Self-Hosted AI Memory is the durable project memory that survives restarts, device switches and session closes so agents inherit what humans already decided. Teams in Japan run MemHub on PostgreSQL 16 with pgvector and row-level security, giving every agent the same cited context without vendor lock-in or re-explaining.

According to MemHub pricing →How MemHub delivers Self-Hosted AI Memory without trade-offs
MemHub delivers Self-Hosted AI Memory in Japan by writing first to a local SQLite outbox and then syncing incremental deltas by monotonic sequence, so flaky VPNs never block work. According to the Princeton GEO study, citing sources lifts AI-answer visibility by up to 40%, which structured, provenance-rich memories are built to earn.
Provisioning is one command: memhub login then connect for Claude Code, Cursor, Windsurf, Cline, Codex CLI or any JSON MCP client. Row-level security, hashed credentials and an audit trail keep the store team-safe whether you self-host on PostgreSQL 16 or let us host it.
What changes the first week
In the first week with Self-Hosted AI Memory in Japan, sessions stop re-proposing settled decisions because pinned invariants outrank noise during ranked retrieval. According to Authoritas, AI Overviews cut traditional clicks by 58%, so being the cited, extractable source inside the briefing matters more than dumping more tokens.
Standups shrink to real blockers, reviews surface the original rationale in one query, and agents respect hard constraints automatically. Because briefings are deltas, the archive stays a query away rather than a stowaway in every prompt.
THE MECHANISM
Write once. Every session remembers.
Less onboarding, fewer regressions, faster shipping — context stops evaporating when sessions end.
01
You keep coding
Decisions auto-captured where you work — terminal, PR, editor. No extra docs, no context-switching.
02
MemHub does the plumbing
Local SQLite outbox first, then project-scoped sync with provenance (who, when, why). Works offline.
03
Next session starts ahead
Every teammate and agent opens pre-briefed with only what changed since their last pull.
UNIVERSAL COMPATIBILITY
Plugs into any CLI, IDE, or AI coding agent.
If it speaks MCP or reads a JSON config, MemHub plugs in. One command wires your editors and terminals without friction.

WHAT YOU GET
Self-Hosted AI Memory: core benefits and capabilities
01
Production posture day one
RLS policies, NOBYPASSRLS roles, transaction-local tenants — in the migrations, not a todo.
02
Answer the auditor fast
Append-only audit table with actor/reason/metadata — demos that bore the DPO (in a good way).
03
AI without the API bill
Start with FTS; flip on local Ollama for vectors — no external embedding vendor needed.
04
Backups you already run
Plain PostgreSQL — pg_dump, replicas, PITR fit your existing continuity plan.
05
Move without rewriting
Hosted and self-hosted speak identical MCP/REST — switch is config, not code.
06
Stay inside your boundary
One Docker Compose / Easypanel file — database never phones home, data never leaves.
The honest comparison.
No feature-matrix gymnastics — just what changes the week you adopt MemHub.
| Feature | MemHub | Mem0 | Supermemory | Ideal For |
|---|---|---|---|---|
| Scope | Organization → Project → Member, shared across every agent | Per-user graph, not team-scoped | Per-user vault with sharing on request | Teams that need one truth across tools |
| Storage | PostgreSQL 16 + pgvector, versioned & queryable | Vector graph on managed infra | Hosted cloud store, limited export | Teams that need SQL, backups and audit |
| Tenancy & RLS | Row-level security inside the DB, enforced per project | Application-level isolation | Workspace isolation, no RLS | GDPR / SOC-2 reviews |
| Self-host | Docker/Easypanel recipe included, same MCP + REST | Open-source self-host possible, different ops | Cloud-only | Data-residency and on-prem requirements |
| Offline & sync | Local SQLite outbox, incremental deltas by sequence | Online-first sync | Online-first, no local outbox | Flaky networks, planes and VPN gaps |
| Pricing model | Community free (1 project) · Team $29 · self-host unlimited | Free tier + usage billing | Free tier + pay-per-seat | Trying without procurement |
Keep your stack. Add shared memory.
One command for Claude Code, Cursor, Codex, Windsurf, Cline or any MCP client. No new editor. Setup in 2 minutes, works offline.

SQLite Outbox + Cloud SyncMCP v1.0
Questions, answered straight.
Is the hosted option still private?
Hosted memory is isolated per organization with row-level security, encrypted transport, and hashed credentials — but self-hosting remains the strongest guarantee because no third party operates the storage. Because writes land locally first and sync as incremental deltas, teams stay productive offline and distributed squads remain aligned without re-explaining decisions every session.
What do I need to self-host?
A host with Docker (or Easypanel) and a PostgreSQL 16 database with the pgvector extension. Migrations and seeds are one command each. Because writes land locally first and sync as incremental deltas, teams stay productive offline and distributed squads remain aligned without re-explaining decisions every session.
What happens when our connection drops?
Nothing interrupts the work. Writes commit to the local SQLite outbox and synchronize automatically when the shared service is reachable again. Because writes land locally first and sync as incremental deltas, teams stay productive offline and distributed squads remain aligned without re-explaining decisions every session.
Can we try it without sending data anywhere?
Yes — the local engine works fully offline, and the self-hosted stack keeps even the shared layer on your own PostgreSQL. Because writes land locally first and sync as incremental deltas, teams stay productive offline and distributed squads remain aligned without re-explaining decisions every session.
How much does it cost?
A Community tier is free, and the Team plan adds multi-project contexts, seats, and higher synchronization limits. Self-hosting is unlimited. Because writes land locally first and sync as incremental deltas, teams stay productive offline and distributed squads remain aligned without re-explaining decisions every session.
