Construct Computer vs Relay: Features, Pricing & Which Is Better (2026)
A side-by-side comparison of Construct Computer and Relay — 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.
