About SideReplay – Test Recorder for .side files & Playwright export
Selenium IDE is no longer available in the Chrome Web Store. If you have tests saved as .side files, SideReplay runs them in Chrome again — no rewrite, no server, no account.
OPEN YOUR EXISTING .SIDE PROJECTS
• Open files saved by Selenium IDE 3.x and 4.x and run them as they are
• All 93 Selenium IDE commands: click, type, select, assert/verify, waitFor, store, echo and more
• Control flow: if / else if / else, while, times, forEach, do / repeat if
• Alerts, confirmations and prompts, iframes (including nested ones) and new windows or tabs
• runScript / executeScript / executeAsyncScript (after you switch on "Allow User Scripts")
• Old command names are converted automatically, and unsupported steps are reported before a run starts
COMING FROM KATALON RECORDER?
• Katalon Recorder is no longer maintained. SideReplay opens the .html test suites it saved
• Data-driven tests (loadVars) run from your CSV or JSON files: the first row free, every row with Pro
• Test files from Selenium IDE 1.x and 2.x open too, and can be saved as .side projects
RECORD NEW TESTS
• Record clicks, typing, Enter, select lists, checkboxes and double clicks
• Follows you into iframes, new tabs and pop-ups, and records how you answered dialogs
• Saves several locators (id, name, CSS, XPath, link text) for every element
SELF-HEALING LOCATORS
• When a page changes and a locator stops working, SideReplay tries the other locators it saved
• It shows which locator worked, and one click updates your test
EXPORT TO PLAYWRIGHT (Pro)
• Turn a whole project into one readable Playwright Test (TypeScript) file
• Assertions become expect(), verify becomes expect.soft(), loops and conditions become real code
• Frames, windows, dialogs and scripts are converted; anything unusual is marked TODO
• Free users can export one test with up to 10 steps to try it
DATA-DRIVEN TESTS (Pro)
• Repeat steps once for every row of a CSV or JSON file, with each column as a variable
• Free users run the first row to check that everything works
HTML REPORTS (Pro)
• Download a single HTML file with every step, result and error message to share with your team
PRIVATE BY DESIGN
• Your tests are stored only in your browser
• No account, no analytics, no tracking
• Only a Pro license key is checked with our payment provider, Polar
