# Optestra > Plain-English end-to-end tests for web, Android, CLI tools and Electron apps. AI writes each test once; every run after that replays it with no AI. The engine, CLI and GitHub Action are open source (MIT); the cloud web app is paid, with a free plan. The desktop app comes after launch. - Start free (cloud web app): https://app.optestra.com/sign-in - Docs (how it works, the test format, the CLI `optestra`, security and data): https://docs.optestra.com/llms.txt - Source: https://optestra.com/launch/#open-source - Pricing, machine-readable: https://optestra.com/pricing.json (v1, USD, last updated 2026-10-10; cloud open) - Everything on one page: https://optestra.com/llms-full.txt - 1 credit = 1 cent. Local runs and writing tests with your own AI key: free, unlimited. A cloud run of 1–20 website tests: 2 credits (+1 per further 20). Android: 2 credits per test, at least 10 per run. A test written with our AI: 10 credits, +5 per 15 steps over 15 (a 40-step test: 20 credits); with your own AI key: 0. Heals: 0. "Explain this failure": 1. Cloud runs of CLI tools are coming soon (paid plans, priced like a website run); comparing two versions costs the two runs it contains, and is free on your own machine. Runs on your own machine, shown in your dashboard: free. - Three ways in: (1) the free open-source engine, on your machines with your AI key; (2) Cloud (your own key), our machines with your AI key; (3) plans with our AI too (Solo Dev, Pro Dev, Team). - Plans (no seat pricing; every feature is on every plan, except cloud CLI runs, which are coming soon to paid plans): Free: $0/month ($0/year), 100 credits (~10 tests written or ~50 cloud runs), 1 parallel runs, results kept 7 days; Cloud (your own key): $5/month ($50/year), 1,000 credits (~500 cloud runs; bring your own AI key, so writing a test costs 0 credits), 2 parallel runs, results kept 14 days; Solo Dev: $8/month ($80/year), 1,600 credits (~160 tests written or ~800 cloud runs), 2 parallel runs, results kept 14 days, +20% on top-ups; Pro Dev: $19/month ($190/year), 4,000 credits (~400 tests written or ~2,000 cloud runs), 5 parallel runs, results kept 30 days, +25% on top-ups; Team: $49/month ($490/year), 12,000 credits (~1,200 tests written or ~6,000 cloud runs), 10 parallel runs, results kept 90 days, shared workspace, +30% on top-ups. - What it tests: Web, Android, CLI tools and Electron apps, in our cloud or on your own machine. Native desktop apps are coming, on your own machine. - Not live yet: the desktop app (after launch), native desktop apps (coming, on your own machine), SMS test numbers, iOS. ## Pages - [Pricing](https://optestra.com/pricing/): plans, credits, top-ups. - [AI E2E testing pricing, 2026](https://optestra.com/compare/ai-e2e-testing-pricing/): what other tools publish, each with its source and date. - [Bench](https://optestra.com/bench/): false passes, wrong fails, flakes and cost, measured, with dates and method. - [FAQ](https://optestra.com/faq/): common questions. - [Security and data](https://optestra.com/security/): which AI sees what, secrets, retention, regions. - [Subprocessors](https://optestra.com/subprocessors/): who handles customer data, and where. ## Comparisons - [Optestra vs TesterArmy](https://optestra.com/compare/testerarmy/): A hosted AI testing agent with inboxes, SMS and iOS simulators, priced per run; against an open engine whose tests live in your repo and replay with no AI. - [Optestra vs Momentic](https://optestra.com/compare/momentic/): A strong AI testing platform with a cloud step cache, visual diffs and mobile, priced in credits per step; ours replays from files in your repo and exports to Playwright. - [Optestra vs QA Wolf](https://optestra.com/compare/qa-wolf/): A managed service where agents and QA engineers write and maintain Playwright for you; we're a tool you run yourself, with English tests that compile to Playwright. - [Optestra vs testRigor](https://optestra.com/compare/testrigor/): A hosted test platform for web, mobile and desktop apps, priced by parallel infrastructure with a public free plan; ours is priced per run, with private files in your repo. - [Octomind alternative](https://optestra.com/compare/octomind/): Octomind, the AI Playwright-test service, shut down in 2026. Its exports were plain Playwright code, so they still run; here is what to do next. - [Optestra vs Playwright Test Agents](https://optestra.com/compare/playwright-agents/): Playwright's free planner, generator and healer write and fix spec code in your editor; we keep an English test as the source, with typed checks, reviewed heals and verdicts. - [Optestra vs DIY Claude Code + Playwright MCP](https://optestra.com/compare/diy-claude-code-playwright-mcp/): A coding agent driving a browser through Playwright MCP is great for one-off checks; tests need recordings, typed checks, verdicts and a way to run without the agent. ## Migration guides - [From Octomind exports](https://optestra.com/migrate/octomind/): Octomind shut down in 2026; its exports are Playwright code. Keep running them, and rewrite the ones you want to maintain as plain-English tests. - [From Mabl](https://optestra.com/migrate/mabl/): Map mabl journeys, flows, variables and credentials to tests, flows, data and secrets, and rewrite each journey as a plain-English test. - [From Cypress](https://optestra.com/migrate/cypress/): What cy.visit, cy.get, cy.contains, fixtures, custom commands and cy.session become, with a worked example. - [From raw Playwright](https://optestra.com/migrate/playwright/): Keep your specs; add plain-English tests next to them; every recorded test is a Playwright spec again.
