MASTRA GATEWAY
Memory and model routing for any AI agent
Give Any Agent Human-Like Memory
Compress chat history into compact memories that help agents remember what matters. Lower token usage and latency without losing important context.
Memory That Never Compacts
Stop interrupting users and losing important details with compaction. Form dense observations in the background without blocking the conversation or throwing anything away.
Observational Memory
Run two background agents — an Observer and a Reflector — that watch your agent's conversations and maintain a dense observation log. Replace raw message history as it grows.
5–40x Compression
Set when and how aggressively conversations compress. Configure observation and reflection thresholds to balance memory density against detail retention.
Prompt Caching
Append observations over time rather than rebuilding each turn. Keep the prompt prefix stable and cacheable — the longer the conversation, the more you save.Route All Traffic Through One Gateway
Use one endpoint for every model. Skip provider SDKs — one API key covers everything.
300+ Models
Access OpenAI, Anthropic, Google, Meta, Mistral, and hundreds more. Integrate once and reach every provider through a single gateway.
High Availability
Run on distributed infrastructure with automatic failover across providers.Works with Any Stack
Change your base URL and start routing through the gateway. Use Python, TypeScript, any framework, any client.Bring Your Own Keys
Plug in your own provider API keys for direct routing to OpenAI, Anthropic, Google, or any provider. Get the same memory features either way.Transparent Pricing

Frequently asked questions
What is Mastra Gateway?
Mastra Gateway is an AI gateway that adds observational memory and unified model routing to any agent. Use one endpoint for every model and one API key for every provider. Observational memory forms dense observations in the background without interrupting the conversation.
How does Mastra Gateway prevent agents from losing context?
Mastra Gateway prevents context loss by running two background agents that maintain a dense observation log without blocking the conversation or throwing anything away. An Observer watches conversations and compresses message history into concise notes about what happened. A Reflector condenses observations when they grow too long. Compression is typically 5-40x.
How does prompt caching work in Mastra Gateway?
Mastra Gateway appends observations over time rather than rebuilding the prompt each turn. Keeping the prompt prefix stable and cacheable means the longer the conversation runs, the more you save.
How does Mastra Gateway route traffic across model providers?
Mastra Gateway is the single integration point for every model provider your agents need to reach. One API key covers everything across more than 300 models including OpenAI, Anthropic, Google, Meta and Mistral, with no provider SDKs required. Change your base URL and start routing through the gateway using Python, TypeScript, any framework, any client. Plug in your own provider API keys for direct routing to any provider and get the same memory features either way. Run on distributed infrastructure with automatic failover across providers.
Does Mastra Gateway work with agents not built on Mastra?
Mastra Gateway works with any agent stack. Change your base URL and start routing through the gateway using Python, TypeScript, any framework and any client. Observational memory and model routing apply to any agent regardless of how it was built.
