Posium is an open‑source, AI‑powered platform that automates end‑to‑end software testing, enabling teams to create, run, and maintain test suites up to ten times faster. Its suite of specialized QA agents handles discovery, planning, code generation, flake resistance, and test maintenance, with the Code Generation Agent able to produce dozens of test cases—e.g., 25 TypeScript tests using Playwright—in a single run. The platform offers a free‑forever plan for unlimited usage.

Problem
Software teams spend extensive time manually creating, maintaining, and stabilizing end‑to‑end test suites, which slows release cycles and leads to flaky or outdated tests that miss critical user flows.
Solution
Posium provides an open‑source, AI‑driven platform that automates the full lifecycle of end‑to‑end testing. A set of specialized QA agents—Discovery, Planning, Code Generation, Flake Resistance, Auto Test Maintenance, and Collaboration—work together to map critical user flows, generate test code in multiple languages and frameworks, and keep the suite stable as the application evolves. The Supervision Agent orchestrates these tasks, allowing teams to produce and update test cases up to ten times faster while reducing manual effort and flakiness. All generated tests follow best‑practice patterns and are delivered through a free‑forever plan, enabling rapid adoption without licensing barriers.
Target Audience
Posium is aimed at development and QA teams that need to accelerate end‑to‑end test creation and maintenance for web applications, including SaaS, e‑commerce, and internal tools.
Features
- Discovery Agent that analyzes an application, identifies its type, authentication patterns, and extracts essential user flows for testing
- Planning Agent that creates detailed test plans covering identified journeys, prioritizing high‑impact scenarios such as checkout and profile management
- Code Generation Agent that automatically writes robust test code across multiple languages and frameworks (e.g., TypeScript with Playwright) with built‑in error handling and retries
- Flake Resistance Agent that detects flaky test patterns and injects stability measures like explicit waits and retry logic
- Auto Test Maintenance Agent that updates existing tests and adds new ones in response to UI or feature changes, keeping the suite current
- Collaboration Agent that facilitates real‑time sharing of test results, issue summaries, and knowledge across the testing team
- Supervision Agent that coordinates all other agents, simplifying the workflow from test planning to maintenance
