Use the Local Playground

Playground

Use built-in examples when you want a safe scratch workspace. Use --project when you want to run against a local SFDX project.

• Start examples without touching project source.
• Persist or reset local org state.
• Inspect snippets, SOQL, DML, limits, traces, and diffs.

glade playground starts a local browser workbench for Apex snippets, SOQL, DML, logs, limits, traces, and local org diffs. It runs from your machine and can use built-in examples, a scratch workspace, or an SFDX project.

Start with built-in examples

Load built-in examples:

glade playground --examples --addr 127.0.0.1:1789

Start on one built-in example:

glade playground --example deal-desk-discount-guard --addr 127.0.0.1:1789 --open

--example uses the managed scratch workspace. It cannot be combined with --project or --project-ref.

Start from an SFDX project

glade playground --project . --db .glade/playground/org.sqlite --open

Print a ready command without starting the server:

glade playground --wizard --project . --examples

Persist or reset local state

Persist playground org state to SQLite:

glade playground --db .glade/playground/org.sqlite --addr 127.0.0.1:1789 --open

Clear the scratch workspace and local org state before startup:

glade playground --examples --reset-on-start --addr 127.0.0.1:1789 --open

--reset-on-start refuses --project so it does not delete project source.

Use memory-only state

Use memory-only org state:

glade playground --no-db --addr 127.0.0.1:1789 --open

Start a local playground server:

glade playground --addr 127.0.0.1:1789 --open

List examples

Print local examples without starting a server:

glade playground --list-examples

What the playground shows

• Load built-in examples and inspect every source file.
• Try a small Apex behavior before adding it to a project.
• Inspect SOQL, DML, limits, traces, and org state in one place.
• Reproduce a compatibility gap before writing a fixture.

Troubleshooting

Use --reset-on-start with built-in examples when the scratch workspace or local org state gets stale. Use --no-db when a run should leave no state on disk.

Try it

Start the local playground with built-in examples:
