BUILD · TEST · LEARN · CONNECT
Aiterrios is a free visual AI agent builder and testing sandbox for basic and intermediate learning. Build node-based workflows, connect your own AI model, learn API integrations and work directly with your agent inside a populated Business Sandbox. Follow real workflow execution using fictional company data.
Free platform access, with no trial countdown and no hidden subscription. You bring your own API key; your AI provider’s charges and usage limits still apply.

I’m a solo developer based in Oslo, Norway, and Aiterrios grew out of a problem that kept interrupting months of work on AI agents: finding somewhere to test them properly. Without realistic data and a way to follow the process, it was difficult to tell whether an agent had actually completed a task or simply produced a convincing answer.
What followed was weeks of digging through GitHub, scattered documentation and Reddit, trying to connect automation platforms with business tools while dealing with expiring OAuth tokens and fragmented test environments. The frustrating part was how much work went into preparing a test before there was anything useful to learn from it. What I desperately needed was a place where an instruction could be followed through a tool call to the record it changed, so that the whole process could be understood rather than guessed at.
Eventually, that search became the reason to build Aiterrios: a free space where someone could put an agent together on a visual canvas, connect it to a populated business environment and learn from the execution logs and the results in front of them, without first having to assemble the entire testing environment themselves.
Learning your way through the AI ecosystem on your own can be frustrating and lonely, and that experience is behind the decision to keep Aiterrios free and give others somewhere to experiment, make mistakes and gradually understand how these systems work. Business is the first sandbox, while the wider idea is to bring more of that learning into one connected universe.
AVAILABLE TODAY · CANVAS
Canvas lets you connect triggers, AI agents, chat models, memory, HTTP tools and data-processing nodes. Configure each step, run a workflow and inspect Logs, Input and Output. Save versions, use templates, import reviewed workflows and publish supported chat workflows.
The node library continues to grow as Aiterrios develops. New nodes and improvements expand what you can build; the public node guides describe supported capabilities.
Give the agent useful toolsOne agent, separate tools for different tasks.
AVAILABLE TODAY · BUSINESS SANDBOX
Your agent can be right there beside the business records. Add a published, supported chat workflow to an Agents slot in Business Sandbox, select it and give it a task from the sandbox’s own chat panel. The connected agent uses your workflow, your model connection and the API tools you authorize.
Business Sandbox comes with a fictional demo company already populated with connected business data: customers, suppliers, invoices, purchase orders, supplier bills and accounting entries. You can start learning without setting up a demo company, entering sample contacts or building a transaction history first. Once your agent’s model connection, API tools and permissions are configured, connect its published chat workflow and start working directly in the sandbox. Ask it to find a supplier, create a draft purchase order or work through an authorized accounting task, then open the related records and follow the result.
You can use your first few days to work through small, concrete tasks and build confidence with API connections, tool calls and business workflows. Start with a lookup, then a draft, then a longer process when you understand the steps. The aim is to make basic-to-intermediate AI agent learning approachable through direct practice.
The platform access and learning environment are free, without a trial period. Your chosen AI provider may charge for model calls. The built-in Aiterrios guide explains the platform; your connected agent performs the work through its configured tools.

Universe adds a social space around the workflow workspace. Create your profile, explore planets and agent satellites, follow people, share posts and participate in conversations. Social visibility and sharing controls are separate from your private business workspace.
More than the workflowA place for people, too.
THE PHILOSOPHY
Aiterrios is genuinely free to use. There is no trial period that ends with a payment screen, and no hidden platform subscription. Inspired by Lichess, the idea is a place where people can learn because they want to learn. Access to that learning environment should not depend on buying a plan.
Aiterrios charges no platform fees or markup on model usage. Connect your own API credentials; your chosen provider sets its prices, usage limits and model availability. Free provider allowances, where available, remain subject to that provider’s terms.
Follow execution steps and check results against the sandbox. AI output can be wrong. External tools can perform real actions when authorized, even though Business Sandbox accounting is simulated.
Saved credentials use server-side AES-256-GCM encryption. Workspace access controls, input validation and approval checks help reduce risks. Review imports, destinations and requested actions before running or sharing a workflow.
THE COMMUNITY WE WANT TO GROW
My hope is that Aiterrios grows into a community-driven platform: people sharing templates, helping each other understand APIs, comparing what their agents do and contributing ideas that make the platform better. That is the direction I want to build toward.
You do not have to arrive as an expert. Bring your curiosity, try the examples and share what you discover. The value of this place should come from what people learn and give back to one another.
WHAT COMES NEXT · PLANNED
Business Sandbox is the sandbox available today. Additional worlds, including Education, Creative, Future Work and Health, are planned to bring new learning contexts to the same visual workspace.
A user-facing data and database workspace is also planned to help connect the full basic-to-intermediate learning journey. These are development plans, not available features or announced release dates. Future worlds remain marked Coming soon until they are ready.
Aiterrios is developed every day, with new nodes and features on the way; updates may cause brief interruptions, but are designed to preserve your profile and saved workflows.
