Posium

Posium is an open-source AI-powered end-to-end (E2E) testing platform for developers and QA teams that want to generate, run, monitor, and maintain automated test suites with AI agents.

Key capabilities include:

• AI agents for the full testing lifecycle, including discovery and test planning, code generation, flake resistance, and automated test maintenance as applications change
• E2E test creation and execution, with a composer UI, scheduled runs, and execution on a cloud platform that includes real mobile device infrastructure
• Debugging and visibility, with analytics plus comprehensive logs, session recordings, and videos, alongside AI-driven test result analysis
• Workflow integrations with common dev, project management, and CI/CD tools such as GitHub, GitLab, Jira, Jenkins, Linear, Slack, and CircleCI

Pricing: Free and Open-source, plus a free forever plan and a 14-day free trial (no credit card required).

Notable for its multi-agent approach to E2E automation (planning, generation, flake reduction, and maintenance), plus built-in support for challenging flows like OTP and 2FA authentication and a focus on reducing flaky tests.
