  • Developers who want to use or run the screener through its CLI or web interface.

  • Review potential market opportunities to inform strategy research.
  • Run a terminal-based screener or the web dashboard from source.
Before you choose

Requirements & limits

  • The CLI requires Go v1.22; running the web frontend locally requires Node v18 and npm v9.
  • Docker v20 and Podman v3 are listed as optional container tools.
  • The README lists Deribit and Delta Exchange, plus Lyra, Thales and Zeta, as supported venues.
  • PsyOptions and Opyn are specifically listed as deprecated integrations, so they should not be treated as current coverage.
  • The CLI and web dashboard are distinct use paths; the web frontend requires the server API.

Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.
