License
The agent server source is available on GitHub, and the software is proprietary.
Agent server
The agent server, with the bundled UI, is installed with pip install search2o from PyPI; see Creating an account and downloading. The source is at github.com/Search2o/agent-server for the agent server and github.com/Search2o/ui for the UI. Use requires a valid, ongoing authorization from Search2o. The license text is the LICENSE file in the repository.
Contributions
External code contributions and pull requests are not accepted at this time. Bug reports, feature requests, documentation feedback and security reports are welcome; the repository's CONTRIBUTING file says where each goes.
UI
The UI is bundled with the agent server under the same license.
Cloud service
Search2o operates Search2o Cloud. Only the agent server uses the cloud's API; the license prohibits calling the API directly.
Search2o Cloud currently operates from the US East region, so an agent server in US East sees the lowest latency. Other regions will follow.
Pricing
An account starts free. Billing starts only when the owner upgrades to the paid service from the Account page. See Pricing.
