Era by Eon
Free simulated companies for testing AI agents: emulated Salesforce, Slack, Jira, Zendesk and more with synthetic data, served over MCP and REST.
Overview
Era is a test environment for AI agents from Eon, the cloud backup company. It generates a complete simulated company on demand: emulated business systems such as Salesforce, Slack, Jira, Zendesk, Gong and Google Drive, filled with synthetic employees, customers, deals and years of history that stay consistent across every system. Your agent connects over per-system MCP endpoints or vendor-compatible REST APIs, so you can test it against a whole software stack instead of mocks or real customer data.
Era launched on October 5, 2026 and is free for builders. Access is granted per account, and the data plane is read-only for now, so it suits evaluating how agents find and reason over enterprise knowledge more than testing agents that write back to systems. Eon also published arXiv research on benchmarking enterprise agents with the same generated companies.
The Verdict
Who Should Use Era by Eon?
Best For
- Teams building enterprise agents that search across CRM, ticketing, chat and docs
- Evaluating multi-hop retrieval over realistic, cross-linked company data
- Demos and CI tests that must never touch real customer records
- Agent builders on Claude Code, Cursor, Codex or Devin (plugins available)
Not Ideal For
- Testing agents that create or update records (writes return an error today)
- Replacing staging or production testing on your real systems
- Teams that need every vendor feature replicated exactly
- Anyone who needs instant self-serve access without an account grant
What's Great
- Free, with nothing to install: generate a company in the browser console
- The same people, customers and deals appear across every emulated system
- Fully synthetic data, so no customer data is exposed during testing
- Sits between artificial public benchmarks and private evals nobody can verify
- MCP, REST, CLI, Docker images for offline CI, and coding-agent plugins
Watch Out For
- Read-only data plane: write calls are rejected
- Emulated APIs do not replace testing on production systems
- Realism is scored against targets, not checked against a real company
- Access is granted per account; some connectors are still "coming soon"
- Very new, with no independent user reviews yet
