Construct Computer vs Mastra: Features, Pricing & Which Is Better (2026)
A side-by-side comparison of Construct Computer and Mastra — features, pricing, and ideal use cases — to help you decide which AI tool fits your workflow.
Construct Computer
Construct
An AI employee with its own cloud Linux computer that runs workflows, builds internal tools, and finishes scheduled work for small teams.
Key features
- Dedicated Cloud Computer: Each user's agent gets a real Linux cloud desktop, so it can run software and produce files rather than only generating text.
- Reusable Workflows: Encode a process once as agent steps, connected apps, and notifications, then version, schedule, and let any teammate re-run it.
- Internal Tool Builder: Describe the tool your team needs and Construct writes, validates, and publishes a working internal app straight into your cloud desktop.
- Scheduled Jobs with History: Schedule an agent prompt, a connected-app action, or a whole workflow to run once or repeatedly, with a full record of results.
- Inspectable Memory: Preferences, decisions, and project context are stored with supporting evidence and history, and can be reviewed, corrected, or forgotten.
- Shared Team Workspace: People, agents, files, apps, and conversations live in one workspace with invitations, roles, and precise access controls.
- Multi-Channel Access: Message Construct from the web, Slack, Telegram, Discord slash commands, or its own native email inbox, with per-channel routing and access policies.
- Cited Research Reports: Gathers sources, compares details, and turns open-ended questions into cited research you can review or share.
- Resumable Long Runs: Jobs that fail partway through resume from where they stopped rather than restarting, targeting reliability on multi-step work.
- Data Ownership and BYOK: Workspaces are isolated and never used as training data, you own the output, and Pro allows bringing your own model keys.
Best for
- Process Automation: Turning a recurring manual business process into a versioned workflow anyone on the team can trigger.
- Internal Tooling: Shipping a small internal app for a team need without pulling in engineering time.
- Inbox and CRM Follow-Through: Letting an agent read, reply, and close the loop across connected tools instead of leaving half-finished automations.
- Market and Topic Research: Producing cited research reports on a subject for review or client delivery.
- Scheduled Reporting: Running a recurring report or data pull on a schedule and keeping the result history in one place.
- Solo Founder Leverage: Handing off operational work as a one-person company without hiring a first operations employee.
- Cross-Channel Team Requests: Letting teammates hand work to the agent from Slack, Discord, Telegram, or email without changing tools.
Mastra
Mastra (team behind Gatsby)
A TypeScript-first agent framework with workflows, memory, streaming, playground, evals, and tracing for building AI apps.
Key features
- Unified Model Interface: Provides a single API to access hundreds of models from dozens of providers (documented access to 1113 models from 53 providers) so developers can switch or compare models without changing application logic.
- Workflows and Orchestration: First-class workflow primitives to compose multi-step agent behaviors and pipelines, enabling complex task decomposition, tool invocation, and sequential processing.
- Long-term Memory: Built-in memory abstractions to persist and recall conversational or agent state across sessions, improving continuity and personalized behavior.
- Streaming Outputs: Support for streaming model responses to enable low-latency progressive output and responsive UX in interactive applications.
- Interactive Playground: A development playground for iterating on prompts, agent strategies, and tool integrations with live testing and debugging.
- Evals and Tracing: Integrated evaluation tooling and tracing to measure agent performance, run automated evaluations, and inspect decision traces for observability and improvement.
- Templates and Example Agents: Ready-made templates (e.g., an AI web search assistant) and sample projects to accelerate building real-world applications.
- Multi-provider Tooling: Facilities to equip agents with external tools, connectors, and integrations while managing provider-specific details through Mastra abstractions.
- TypeScript-first agent framework optimized for modern TypeScript stacks
- Workflow orchestration for multi-step agent behaviors
- Persistent memory management for agents
- Streaming response support for real-time output
- Interactive playground for developing and testing agents
- Evaluation tooling (evals) for measuring agent performance
- Tracing and observability for agent executions
- Unified model interface providing access to 1,113 models from 53 providers via a single API
- Templates and example applications (including a web search assistant)
- Open-source repository and community resources (mastra-ai/mastra on GitHub)
- Course and learning materials for building and deploying agents
Best for
- Building autonomous TypeScript agents that coordinate tools, perform multi-step reasoning, and maintain state with memory across interactions.
- Creating an AI-powered web search assistant that crawls, extracts, and sources open-web information using Mastra templates and connectors.
- Comparing and switching LLM providers easily during development by leveraging Mastra's unified model interface to test dozens of models without rewriting code.
- Developing production workflows that stream partial model outputs to users for real-time feedback while tracing and evaluating agent decisions.
- Prototyping and evaluating agent strategies using the interactive playground and built-in evals to iterate on prompts and measure performance.
- Teaching and onboarding teams through the Mastra course to learn how to equip agents with tools, memory, and MCP patterns in a TypeScript environment.
- Packaging TypeScript-based AI applications with reproducible workflows, templates, and observability for deployment and maintenance.
- Building tool-enabled conversational agents with memory and multi-step workflows
- Creating web search and information retrieval assistants with sourced answers
- Rapidly prototyping and testing agent behavior in an interactive playground
- Integrating many LLM providers through a single unified API for model experimentation
- Deploying production agents with tracing, evals, and observability
