Maximem Synap
Managed memory and context layer for AI agents
Editorially reviewedChecked Oct 2026How we review
Free plan API Browser extension
Toolglade’s take
Synap is a serious entrant in the crowded agent memory space alongside Mem0, Zep, and Letta, and its pitch of every capability on every plan with tiers only by volume is buyer-friendly. Published benchmark scores are strong, but they come from the vendor harness, so run your own evals before switching. The engine is closed source and cloud-managed, with on-prem only on Enterprise. The 19 dollar Starter price is a launch offer against a 49 dollar list price. Category is coding as the nearest fit for developer infrastructure.
Should you use Maximem Synap?
- Best for
- AI agent developers · Startups building assistants · Teams replacing homegrown RAG memory

- Biggest strength
- Every capability on every plan
- Biggest weakness
- Memory engine is closed source

About Maximem Synap
Maximem Synap is a managed memory layer for AI agents that ingests conversations, builds structured graph memory, and serves fast, relevant recall through SDKs for 20-plus agent frameworks.
Maximem Synap addresses a common agent problem: every conversation starts from zero. Synap runs as a fully managed cloud service with client SDKs, so developers ingest conversations and documents, and Synap extracts structured knowledge into graph memory and serves it back at retrieval time. Teams do not need to run or tune a vector database, reranker, or retrieval pipeline. The service offers fast, hybrid, and accurate retrieval modes, agentic compaction, anticipatory retrieval, consolidation, A2A protocol support, REST and WebSocket APIs, webhooks, and custom memory schemas, and all plans get every capability, with tiers differing by volume and support level. It integrates natively with more than 20 agent frameworks including LangChain, LangGraph, LlamaIndex, CrewAI, Google ADK, AutoGen, OpenAI Agents, Semantic Kernel, Haystack, Pydantic AI, and the Claude Agent SDK. Synap launched on Product Hunt on September 24, 2026. Maximem publishes its own benchmark harness and claims leading LongMemEval and LoCoMo scores; buyers should validate on their own workloads. The memory engine is not open source, though Enterprise plans list an on-premise option.
