Alfe vs Mastra

A framework you host, or an OS that hosts the agent for you.

Mastra is a polished open-source TypeScript framework for building agents — you write the code and run the infrastructure, storage, and ops yourself. Alfe is the managed substrate underneath a live agent: a dedicated per-agent server, one USD credit pool across 9 model providers, managed vector + knowledge-graph memory, channels, and voice — running the moment the agent boots.

Why teams pick Alfe

Where Alfe pulls ahead of Mastra.

Mastra gives you primitives; Alfe gives you a substrate

Mastra is a genuinely good TypeScript framework — agents, workflows, memory types, and a model router with fallback. But it's a library: you still stand up the servers, wire a storage backend for memory, and own the ops. Alfe is the managed layer that runs a live agent — dedicated per-agent compute, managed memory, channels, and voice — so there's no infrastructure to build before the agent is answering messages.

Memory with no backend to run

Mastra bundles working memory, semantic recall, and observational memory — but every one of them needs an external store you provision and maintain (PostgreSQL, LibSQL, or Redis). Alfe ships a managed semantic vector store plus a knowledge graph out of the box, persistent from the first message, with an interactive memory-map view in the dashboard. Nothing to provision.

One credit pool, not a router you feed keys

Mastra's model router reaches 90+ providers — but you hold every provider's API key and pay each of them directly. Alfe routes 9 providers through one proxy and meters everything into a single tenant-wide prepaid USD credit pool: one bill, bounded spend, no key rotation. Bring your own key per tenant if you prefer.

Not just TypeScript

Mastra is TypeScript-only, which shuts out teams standardized on Python. Alfe is a managed platform, not a library you import — it runs OpenClaw or Hermes runtimes on your agent's server regardless of your own stack, and you talk to it over MCP, channels, and the agent API.

Where Mastra genuinely wins: it's open and free

Mastra's core is Apache-2.0 and free to self-host — if you want full code-level control and no vendor in the loop, that's a real strength Alfe doesn't match. Alfe is a paid managed platform. The trade is ops: you own the servers, storage, and scaling with Mastra; Alfe owns them for you.

FAQ

Alfe vs Mastra — common questions.

Is Alfe a Mastra alternative?

For a different buyer. Mastra is an open-source TypeScript framework you build with and host yourself; Alfe is a managed platform that runs a live agent for you. If you want full code-level control and don't mind operating infrastructure, Mastra is excellent. If you want an always-on hosted agent with managed compute, memory, channels, and billing, Alfe covers the ops layer Mastra leaves to you.

Is Mastra free? Isn't that cheaper than Alfe?

Mastra's core is Apache-2.0 and free to self-host, and that's a real advantage — but 'free' is the license, not the running cost. You still pay for your own servers, a storage backend for memory, each model provider directly, and your team's ops time. Alfe is a paid platform that folds compute, models, memory, voice, and channels into one prepaid USD credit pool. Which is cheaper depends on whether you'd rather run infrastructure or buy it managed.

Do I have to bring a storage backend for memory like I do with Mastra?

No. Mastra's memory types require you to provision PostgreSQL, LibSQL, or Redis. Alfe ships a managed semantic vector store and a knowledge graph out of the box — persistent from the first message, with nothing to provision or maintain.

Can Alfe reach as many model providers as Mastra's router?

Mastra routes to 90+ providers; Alfe pools 9 (OpenAI, Anthropic, DeepSeek, Google Gemini, MiniMax, Mistral, xAI/Grok, OpenRouter, Zhipu/GLM) — and via OpenRouter reaches many more. The difference is billing: Mastra's router expects you to hold and pay each provider's key, while Alfe meters all 9 into one credit pool with an approved-model policy and per-tenant BYOK override.

Pricing

Pricing for fleets, not seats.

A tenant-wide credit pool funds compute, model usage, voice minutes, channels, and storage. Managed agents are add-ons on one subscription — your plan includes some, and you add more as you grow.

Skip the infrastructure, keep the agent.

Mastra hands you the framework and the ops. Alfe runs the agent — dedicated compute, one credit pool across 9 providers, managed memory, channels, and voice — managed for you.
