Mem0 vs SuperMemory vs Zep vs Audaxic (2026 Comparison)
Choosing a memory layer for coding agents in 2026? Here’s a head-to-head of Mem0 Platform, SuperMemory, Zep (temporal memory), and Audaxic — the cheapest flat-priced option on Cloudflare edge. Same quotas compared, no marketing fluff.
The short answer
If you want the cheapest persistent memory for Claude Code, Codex, and OpenCode with MCP and flat pricing, Audaxic wins on price at every tier. If you need temporal knowledge-graph with time-decay, Zep is strongest (but pricier and self-host heavy). SuperMemory is a solid Notion/Drive-integrated option, but usage-based with auto top-up. Mem0 is the incumbent but Pro-only graph and 1–3 project limits hurt coding teams.
Pricing — same quotas, different bills

When to pick which
Pick Audaxic if: you run Claude Code, Codex, or OpenCode daily and want the cheapest persistent memory with flat billing and zero ops. You get MCP + plugins + import tool (@audaxic/memory-import) included. See also mem0 alternative.
Pick Mem0 if: you already have mem0 Cloud and need enterprise features (more than unlimited projects per org is edge case, but you’re locked in).
Pick SuperMemory if: you need Notion/Drive/Gmail connectors for non-coding use (docs, email memory) and don’t mind usage-based pricing.
Pick Zep if: you need temporal graphs (time-aware memory) and are comfortable self-hosting or paying premium for recency decay. Great for assistants, overkill for “remember my coding preferences.”
Switching note
Audaxic REST has mem0-like shapes — point your client at https://api.memory.audaxic.com with your ak_ key and verify against our docs. For Zep/SuperMemory, map SDK calls to /add + /search. Full: quickstart.
