SeleniumBase
SeleniumBase is an open-source Python framework for browser automation, web scraping, and end-to-end UI testing. It builds on Selenium/WebDriver and pytest (also supporting pynose and behave) while adding higher-level APIs, reporting, test-generation, stealth automation, and integrations.

Products & Services
MIT-licensed Python framework and package for browser automation, web crawling/scraping, and end-to-end testing. Provides BaseCase, SB context-manager, Driver manager, pytest/pynose/behave support, automatic driver management, waits, screenshots, logs, dashboards, and reports.
Undetected/stealth browser-automation mode designed to reduce bot-detection signals and support CAPTCHA-oriented workflows.
Stealth automation using Chrome DevTools Protocol; Pure CDP Mode drives Chrome without WebDriver and can be used for scraping and bot-detection-avoidance workflows.
Model Context Protocol server that exposes SeleniumBase Pure CDP Mode as browser-automation tools for MCP clients such as Claude; distributed through the SeleniumBase package extra and repository mcp_servers folder.
Market Position
SeleniumBase positions itself as a higher-level, batteries-included alternative to raw Selenium/WebDriver: it adds test-runner integration, automatic waits and drivers, reports/dashboards, GUI and recorder tooling, and a large helper API. Its differentiators are UC/CDP stealth modes, Pure CDP automation, stealthy Playwright support, and an MCP server; adjacent competitors include raw Selenium, Playwright, Puppeteer, and other Python browser-automation/stealth frameworks.

Founding Story
The public record presents SeleniumBase as a developer-created Python framework intended to make Selenium/WebDriver-based browser automation and testing more productive through a structured test runner, higher-level commands, automatic driver handling, reporting, and cleaner failure output. The first located PyPI release was 1.8.7 on April 8, 2018.
Business Model
Revenue Model
SeleniumBase is distributed as free, open-source MIT-licensed software through GitHub and PyPI. The public materials reviewed describe package installation and optional integrations/MCP extras, but do not document a paid subscription, API-usage, license, or enterprise pricing model.
Pricing Tiers
Installable from PyPI with pip and available under the MIT License; the MCP functionality is available via the seleniumbase[mcp] extra.
