Mainframe 3270 automation and web tooling for modern engineering workflows.

Repeatable scripted workflows to replicate human 3270 online integration at unlimited scale. Includes a web dashboard, API, and CLI for functional and non-functional testing of mainframe 3270 online applications.

• Docs: https://3270connect.3270.io
• GitHub: https://github.com/3270io/3270Connect
• Highlights:
  • Define and execute automated workflows via configuration files
  • Capture 3270 screen state for documentation and troubleshooting
  • Run workflows in parallel for faster validation
  • Headless mode for CI/CD automation
  • API server for load testing and advanced orchestration
  • Prometheus /metrics endpoint for connect/step timing and live worker counts
  • Host compatibility profiler producing 3270Web-compatible JSON for cross-environment diffs
  • Hardened input handling: injection, filename, and path-traversal prevention

Web-based 3270 terminal interface in Go with AI Chat, session recording, and a 3270Connect-compatible workflow.

• Docs: https://3270web.3270.io
• GitHub: https://github.com/3270io/3270Web
• Highlights:
  • Browser UI for interactive 3270 sessions with detailed logging
  • Virtual keyboard support for full terminal interaction
  • AI Chat side panel for conversational screen reading, guided actions, and chaos exploration with explicit approval
  • AI Chat model selector — switch between Copilot models (default Claude Opus 4)
  • Chaos mode support for randomized session testing
  • Chaos Mind-Map Compare API for diffing host divergence across environments
  • Host compatibility profiler API producing 3270Connect-compatible JSON
  • IBM 3270 terminal fonts (Regular, Semi-Condensed, Condensed) bundled with the app
  • Export sessions as workflow.json compatible with 3270Connect
  • Load and replay workflow.json for repeatable flows
  • Docker image and GHCR publishing workflow

Use 3270Web to interactively build and record terminal sessions, then run those same workflows at scale with 3270Connect in local, CI/CD, or load-testing pipelines.
