ESDB — Installation¶

License¶

The chronomemory ESDB engine is proprietary software — a commercial license is required. Contact licensing@layer1labs.ai. Terms: COMMERCIAL-LICENSE.md (ChronoMemory only).

If you use specsmith, the simplest path is pip install "specsmith[esdb]". See the ESDB overview for the full two-tier licensing summary.

# Via pip:
pip install "specsmith[esdb]"

# Via pipx (if specsmith is pipx-managed):
pipx inject specsmith "chronomemory>=0.2.4"

Activate your license key:

specsmith esdb enable --key-file /path/to/your.esdb.key
specsmith esdb status   # confirms ChronoStore is active

pip install chronomemory

Add to pyproject.toml:

[project]
dependencies = [
    "chronomemory>=0.2.4",
]

Zero runtime dependencies — pure Python stdlib (hashlib, json, os, shutil, pathlib).

import chronomemory
print(chronomemory.__version__)   # 0.2.4

from chronomemory import ChronoStore, ChronoRecord, EsdbBridge
print("OK")

Or from the command line:

python -c "import chronomemory; print(chronomemory.__version__)"

pip install "chronomemory[docs]"
mkdocs serve   # preview at http://localhost:8000

chronomemory has zero runtime dependencies. It uses only Python stdlib: hashlib, json, os, shutil, pathlib, dataclasses, typing.

This is enforced by CI: the package is installed with --no-deps and the dependencies field is asserted empty.
