Pick an extension by the capability you need.
| Category | What it covers |

| Editor intelligence | Type-aware completions, hover documentation, signature help, diagnostics, go to definition, and quick fixes inside the native editor. |
| Theming | Color themes, Zen modes, font controls, and visual editor customizations. |
| GitHub sync | Push, pull, diffs, and repository workflows that connect an Apps Script project to source-control services. |
| AI assistance | Chat, inline suggestions, or code-editing agents. Scopes and AI-provider arrangements vary by extension. |
For a local project and command-line deployment workflow, compare the native editor with VS Code and clasp.

Use myFunction with other extensions.
A theme or editor-productivity extension can run alongside myFunction when you want a different look. Use a GitHub-sync extension when the project needs source control.
myFunction is for people who want type checking, diagnostics across every file, and quick fixes without leaving script.google.com. It does not replace a local Git workflow.
For more on completions and type checking, see Apps Script autocomplete. Read what myFunction can access in security and data handling.
