Kombai can perform actions like navigating to different pages, clicking on buttons, and filling out forms to test your applications. To start using the browser autonomously, ask Kombai to perform a task in the Kombai Browser.

​
Capabilities

Kombai can open new tabs, list and switch between open tabs, and close tabs or the whole browser window to test multi-page and multi-window flows.
Kombai can identify interactive elements in your interface and test the clickability of these elements. It can perform clicks, double clicks, right-clicks and hover actions on any visible element on the webpage like buttons, links, and form fields.
Kombai can identify an input field and type text into it. It fills out forms, submits data, and interacts with text areas and search boxes.
Kombai can scroll lengthy pages to reveal more content, find specific elements, and explore large documents.
Kombai can take screenshots to understand page layouts, verify visual elements, and provide visual confirmation of its browser actions.
Kombai can select a rectangular region of the page and detect the elements inside it, returning a cropped image along with the matched elements. This helps when an area is easier to point at by coordinates than to describe by selector.
Kombai can read the page’s DOM structure and the computed CSS of any element, covering layout, typography, color, spacing, borders, flex/grid, transforms, and more. It uses this to understand how the UI is built before it suggests or makes changes.
On React apps, Kombai can map any element to its nearest React component and read the component’s name, props, state, and source file location. This traces what you see on screen back to the code that renders it.
Kombai can detect the UI frameworks running on a page (such as React, with its version) to tailor how it inspects and edits the application.
Kombai can read the CSS custom properties (variables) declared on the page, such as your color, spacing, and typography tokens, so its style changes stay consistent with your design system.
Kombai can make live, in-page changes to preview a result before writing any code, including applying or removing CSS, editing text, moving or deleting elements, and injecting fonts or animations.
After editing your source, Kombai can wait for the dev server’s next Hot Module Replacement event (Vite, Webpack, Next.js, Turbopack, Remix, Parcel, esbuild) before re-inspecting. This enables a reliable edit, reload, and verify loop.
Kombai can monitor the browser console to troubleshoot problems and check page behavior by reading JavaScript errors, network warnings, and debugging output.
Kombai can monitor the page’s HTTP requests and responses, allowing it to track API calls, analyze payloads, check status codes, and diagnose network issues.
Kombai can measure the page’s performance, including Core Web Vitals (LCP, CLS, INP, FID) with good / needs-improvement / poor ratings, loading metrics (FCP, TTFB, TBT, TTI), transfer size, and JavaScript heap usage, to help identify and optimize performance bottlenecks.
Kombai can audit the current page for accessibility and SEO issues and report what to fix.
