Anvia and Mastra ​

Last reviewed: August 2026

Mastra is an integrated TypeScript framework for agents and AI applications. It combines agents, tools, workflows, memory, retrieval, MCP, server/deployment support, development Studio, and observability. Anvia covers much of the same problem space, but splits it into an injected SDK runtime, focused adapter packages, a local Studio, and a separate self-hosted Lens product.

What Mastra does especially well ​

Mastra’s official agent overview describes agents as open-ended model-and-tool loops that can retain memory, return structured responses, and participate in workflows or multi-agent systems. Registering an agent with the central Mastra instance makes shared storage, logging, observability, and the agent registry available to it.

Mastra draws a useful distinction between open-ended agents and predetermined workflows. Its workflow system supports schema-defined steps and sequential, parallel, branching, and looping control flow, with graph inspection in Mastra Studio.

The framework also has a broad application platform around the runtime. Official Mastra documentation covers typed tools and MCP, memory, retrieval, server adapters, deployment, scorers/evaluations, and logs, metrics, and traces. This integrated path is attractive when a team wants one framework vocabulary across authoring, development, deployment, and operations.

Where the overlap is real ​

Both Mastra and Anvia include:

  • reusable agents with instructions, models, tools, and memory;
  • direct generation and streaming;
  • schema-validated structured output;
  • typed tools and MCP connectivity;
  • deterministic workflows or pipelines;
  • retrieval and vector-store integrations;
  • multi-agent composition and runtime context;
  • local development inspection;
  • tracing and evaluation integrations.

Neither project has exclusive ownership of these patterns. The decision is about how they are assembled and operated.

The architectural difference ​

Mastra organizes capabilities around a framework instance and registration model. Agents and workflows gain access to shared framework services, and the same ecosystem includes a server, client SDK, Studio, deployment paths, and Mastra’s observability platform.

Anvia starts with smaller runtime shapes:

  • a completion for one model call;
  • an agent for a model-directed loop;
  • an extractor for validated data;
  • a pipeline for known stages and control flow.

Application code constructs provider models, memory stores, vector indexes, tools, observers, and services, then injects them. There is no required central application container. Packages expose these adapters independently.

Anvia deliberately separates the two operational surfaces. Studio is a trusted local console attached to live runtime objects. Lens is a self-hosted production observability and evaluation workspace. This separation can suit teams that want the runtime deployment and telemetry deployment to have different security, scaling, and retention boundaries.

Choose Anvia when ​

Anvia is a good fit when:

  • dependency-injected runtime objects should fit inside an existing server architecture;
  • provider models and storage adapters should be independently replaceable packages;
  • the application needs first-party provider-neutral contracts for image, audio, transcription, OCR, embeddings, and model listing;
  • local debugging and production observability should be separate deployments;
  • self-hosting the Lens operational workspace is an explicit requirement;
  • the team prefers pipeline and runtime lifecycle APIs without adopting an application framework container.

Choose Mastra when ​

Mastra is a strong fit when:

  • the team wants agents, workflows, storage, retrieval, server APIs, Studio, deployment, and platform tooling under one framework;
  • registering components in a shared Mastra instance matches the application architecture;
  • Mastra’s model router and AI SDK ecosystem already fit the model layer;
  • Studio visualization and Mastra’s integrated observability/scorer path are central to the workflow;
  • the team prefers framework conventions and scaffolding over assembling focused packages.

Can they coexist? ​

Yes, but running one framework’s agent loop inside the other should be an explicit service boundary rather than an object cast.

Useful coexistence patterns include:

  • expose a Mastra or Anvia agent over HTTP and call it from the other runtime as a bounded tool;
  • expose capabilities through MCP when discovery is useful;
  • use one stack for synchronous product agents and the other for an isolated workflow service;
  • export telemetry from both services to a shared OpenTelemetry backend.

For migration, choose one authoritative owner for each conversation and workflow run. Move the model/tool loop first, then map memory records, approval states, and stream events deliberately. Mastra and Anvia have different message, tool, storage, and execution types, so a compile-time adapter is safer than sharing database tables directly.
