Five-minute emulator quickstart

Requires Python 3.11–3.13. The local path uses no network and no credential.

python -m venv .venv
. .venv/bin/activate
python -m pip install geyser-sdk==0.1.0b4 geyser-open==0.1.0b4
geyser init tool careful-search
geyser validate careful-search
geyser test careful-search
geyser dev careful-search

Run python examples/emulator_quickstart.py from the source repository to observe admission, durable event ordering, an exact-bound approval, a consequential tool receipt, a checkpoint, and completion. A successful local test is not runtime qualification or production authority.

Read the example source or continue with the sync and async SDK clients.
