| Dimension | ContextStream | Mem0 / OpenMemory |
|---|---|---|
| Product center | A complete AI platform: build with agents in a shared project workspace, or bring precise code search, memory, decisions and coordination to your MCP editor. | A general-purpose memory layer for AI agents and applications, with OpenMemory adding coding-agent workflows. Mem0 overview ↗ |
| MCP access | A ContextStream MCP server connects supported coding assistants to project memory, code search, and structured project tools. | Mem0 documents MCP access and coding-agent plugins, including Claude Code, Cursor and Codex. MCP docs ↗ |
| Project and team scope | Workspaces, projects, scoped shared memory, team roles, and project-level access controls are part of the product model. | Mem0 supports organizations, projects, members, and isolated project data. Project docs ↗ |
| Graph context | Code dependency, call, dataflow, and type relationships sit alongside a structured project-knowledge graph. | Mem0’s native Graph Memory connects entities across memories and uses those connections to improve retrieval on all plans. Graph Memory docs ↗ |
| Coding workflow | Build with specialist agents, coordinate work across sessions, surface decision conflicts, and review source-linked results in one workspace or your MCP editor. | OpenMemory is designed for coding agents and project-scoped memory; evaluate it alongside the code-analysis stack your workflow needs. OpenMemory ↗ |
Choose for the workflow around memory.
You are building the memory layer.
Mem0 is a natural candidate when you are embedding memory in your own agent or application, want its managed platform or open-source path, or prefer to assemble the surrounding coding and project-knowledge stack yourself.
You want a coding-project context system.
ContextStream is the more opinionated fit when code search, structural code graphs, durable decisions and lessons, plans, runbooks, handoffs, and continuity across coding assistants should arrive as one project workflow.
Test a real project for free.
Starter includes 10,000 Context Credits each month, unlimited workspaces, up to 15 projects, and persistent memory. Pro starts at $19/month with 25,000 credits; Elite is $49/month with 100,000 credits. Every plan includes the same core platform, full graphs and Enhanced Context.
Read the method, not a head-to-head claim.
ContextStream reports 90.0% accuracy on LongMemEval-S and 99.38% Recall@10 in its published code-search evaluation. These are ContextStream measurements, not a direct comparison with Mem0.
Evaluate ContextStream against your own project.
Connect a supported coding assistant, index one repository, and test whether the next session can retrieve a real decision and the code it affects.
