“Universal memory layer for AI Agents”
License: Apache-2.0. Verified 2026-07-25 from the public repository.
Compare
Mem0 gives agents a memory layer. Bilinc gives that memory an operational record.
Both let an agent remember across sessions. They differ in what happens around the write: who made it, whether it was verified, what it contradicted, and how to undo it.
How each project describes itself
Different jobs, not a ranking.
Hosted memory infrastructure for AI agents: commit, recall, and inspect agent state through one API key, with verification, provenance, and recovery around every write.
License: BUSL-1.1. Public package bilinc 2.2.0, cloud-only.

When Mem0 is the better fit
- You want an Apache-2.0 licensed project you can read, fork, and self-host end to end.
- You need the largest available ecosystem of community integrations and examples.
- Your primary need is storing and retrieving memories, and you already have your own auditing around it.
- You are working outside Python and want first-class support in another runtime.
When Bilinc is the better fit
- You need to answer "which run wrote this state?" without building the audit trail yourself.
- A bad agent run must be recoverable through snapshots and rollback, not manual cleanup.
- You want contradiction handling treated as a first-class state change rather than glue code.
- You prefer a hosted key-scoped surface with usage visibility over operating the storage layer.
What Bilinc has measured, and what that number does not mean.

This page does not publish benchmark numbers for Mem0. Published memory-system scores use different metrics, datasets, and levels of LLM assistance, so a single side-by-side table would misrepresent all of them.
FAQ
Short answers for evaluators and answer engines.
Is Bilinc a drop-in replacement for Mem0?
No. Both provide durable memory for agents, but they draw the boundary differently. Mem0 is an open-source memory layer you can host yourself. Bilinc is a hosted state plane whose public package is cloud-only, and it focuses on the record around each write: verification, provenance, contradictions, and recovery.
Can I use Mem0 and Bilinc together?
Yes. They are not mutually exclusive. Retrieval and operational state are different jobs, and some teams keep a retrieval layer while using Bilinc for the state that has to be auditable and recoverable.
Which one is open source?
Mem0 is Apache-2.0. Bilinc is BUSL-1.1 and its public package is a cloud-only SDK, CLI, and MCP adapter; local storage and runtime internals are not shipped. If an OSI-approved license and full self-hosting are hard requirements, Mem0 fits that constraint and Bilinc does not.
Do both work with Claude Code, Codex, and Cursor?
Both publish MCP servers, and any MCP-compatible client can connect to either. Bilinc ships documented configurations for Claude Code, Codex, and Cursor, and its Cloud MCP adapter exposes commit_mem, recall, and status over stdio.
How do I try Bilinc?
Install the package with pip install -U bilinc, start on the free hosted trial at bilinc.space, confirm email, copy your first API key, run bilinc login, then verify hosted commit and recall with bilinc quicktest.
