| Dimension | ContextStream | Mem0 / OpenMemory |
|---|---|---|
| Product center | An opinionated context system for coding projects: code, decisions, lessons, runbooks, plans, and handoffs. | 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 provides an official MCP server for supported clients. 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 Graph Memory models entities and relationships to improve memory retrieval. Graph Memory docs ↗ |
| Coding workflow | Code search and structural analysis are packaged with durable decisions, lessons, plans, and cross-tool session continuity. | 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 3,000 Context Credits each month, up to 5 workspaces, up to 15 projects, and 5-day memory retention. Pro starts at $19/month; Elite starts at $49/month for deeper graph context and a larger monthly credit pool.
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.
