FastEdge applications can be scaffolded, built, and tested entirely outside the Gcore Customer Portal, before anything reaches the edge. Four tools cover different parts of that workflow: an AI plugin that automates the full cycle through natural language, an editor extension with a visual debugger, a headless test framework built for CI, and a command-line tool that runs a compiled binary from a terminal.

Tool comparison

Each tool targets a different point in the development cycle, and the choice depends on how much of the workflow needs to run through an editor versus a script: AI-assisted development plugs gcore-fastedge into Claude Code, Codex, or Cursor, so a plain-language request scaffolds, builds, and deploys an application through the bundled MCP server. The FastEdge extension compiles and runs an application locally inside VS Code, with a bundled debugger and request panel for inspecting responses without leaving the editor. Test framework runs the same compiled binaries in Node.js: headless suites for CI, or the same browser debugger the VS Code extension bundles. FastEdge CLI serves a compiled binary as a local HTTP server, so the application can be tested from a terminal without a new deployment. The VS Code extension bundles the same CLI. Source code and issues for gcore-fastedge and FastEdge-mcp-server are in the same GitHub organization as FastEdge-vscode and FastEdge-test.
