Mastra alternatives that run agents, APIs, and approvals on one flat bill.
Mastra Platform bills on observability events, CPU hours, data egress, always-on servers, memory tokens, and database usage, starting at $250 a month on the Teams plan. Workflows are written in TypeScript only, and RBAC and audit logs sit on the custom Enterprise plan.
Unmeshed counts one flat number per workflow execution. You define workflows in JSON, YAML, or code, and agents run next to your APIs, batch jobs, and human approvals in the same workflow.

Overview
About Unmeshed
Unmeshed is a workflow orchestration platform built by the team behind Netflix Conductor. You define workflows in JSON or YAML, with code-based workers in Java, Go, TypeScript, or Python. Agents run as steps next to plain code, API calls, and human approvals, and the engine keeps state, retries failed steps, and records every run.
About Mastra
Mastra is an open-source TypeScript framework for building AI agents and AI-powered apps, with workflows, memory, MCP, evals, and observability built in. The core framework is free under the Apache 2.0 license. Mastra Platform adds hosted deployment, Studio, and observability on a Starter, Teams, or custom Enterprise plan.

Pricing
Mastra pricing has a plan fee and a meter for almost everything else. Ours is one number.
Mastra Platform starts free, then moves to $250 a month on Teams. On top of the plan, it bills events, CPU hours, data egress, always-on servers, memory tokens, retrieval storage, and database usage.
Unmeshed lists three plans with prices on the page, counts one flat number, a workflow execution, and lets you move from free to paid yourself.

Agentic AI
AI agent orchestration, with the rest of the workflow around it
Mastra
Mastra is a strong agent framework. It gives you typed agents, memory, evals, traces, and cost and latency metrics, all in TypeScript. The focus is the agent and the code that defines it.
Unmeshed
Unmeshed treats an agent as one step in a larger workflow. The same engine runs your APIs, batch jobs, decisions, and human approvals around it, so the whole process lives in one place. If you already build agents in Mastra, keep them. Call them from an Unmeshed worker and let Unmeshed handle state, retries, and audit.
Cost and infrastructure
Free to self-host. Governance needs a license.
Mastra
Mastra's open-source framework is free to run anywhere, and its self-hosted Enterprise option uses a flat annual fee, which is worth saying plainly. The catch is that RBAC, SSO, and IAM integration come from that licensed Enterprise tier, and the hosted platform adds its own usage meters.
Unmeshed
Unmeshed self-hosts the whole platform on your own VM or Kubernetes cluster, or you can use Unmeshed Cloud, and you choose without a sales call first.
Feature comparison
Mastra makes you plan for this. Unmeshed already did.
The stuff you won't have to build yourself.
Pricing predictability
One number, not a meter for each resource.
Unmeshed
Workflow executions are counted flat, no matter how many events, CPU hours, or tokens a workflow uses.
Mastra
Teams is $250 a month, then events, CPU hours, egress, memory tokens, storage, and databases are billed on top.
Workflow definitions
Define it your way, not only in TypeScript.
Unmeshed
Workflows are defined in JSON, YAML, or code, with workers in Java, Go, TypeScript, or Python.
Mastra
Workflows and agents are written in TypeScript, so every change goes through a TypeScript developer.
Governance
Access control before the Enterprise deal.
Unmeshed
Role-based access control is available as a baseline platform capability, not held for a custom conversation.
Mastra
SSO arrives on Teams, while RBAC and audit logs are Enterprise features.
Self-hosting
The whole platform, with governance included.
Unmeshed
Self-host on your own VM or Kubernetes cluster, or use Unmeshed Cloud, control plane included. On-premises deployment is included on the Enterprise plan.
Mastra
The open-source framework is free to host, and the licensed self-hosted tier adds RBAC, SSO, and IAM on a flat annual fee.
Code sample
Plain functions. TypeScript if you like.
Workers are plain functions. Register them, start a process, and the platform handles state and retries, whether a step calls an agent or just moves data. Write them in TypeScript, Java, Go, or Python.
Retries, state, and scheduling come built in, so there's no extra worker setup to hand roll.
