One script tag. Every framework.

Actions

The button itself — six variants, six tones, every size and state, the click effects, and the guards that stop an action being taken twice.

Groups

The two components built out of the button: a group that is one widget with one Tab stop however many buttons are in it, and a split button whose menu is the real bmx-menu rather than a copy of one.

Fields

Input, textarea, a virtualised select and combobox, a date picker and an upload field. The controls you type, search or drop into.

Choices

Checkbox, radio group, switch, slider and rating. The controls you toggle, slide or score with.

Navigation

Menu, tabs, accordion, a toolbar that collapses what does not fit into a menu, a breadcrumb that collapses its middle, pagination and a splitter.

Feedback

Dialog and drawer over a native modal in the browser's top layer, the tooltip and popover pair — one describes, the other contains — a toast with a queue behind it, and progress and skeletons for the waiting.

Display

Badge, chip, avatar and the two sets that hold them — the components that label what is already on the page. A count that reaches the control it belongs to, a chip that is three different elements, and a stack of faces that says who is behind it.

Applications

The large components — a carousel over the platform's own scroller, a calendar whose layout is arithmetic rather than pixels, and an org chart that is a tidy-tree algorithm behind a diagram. Applications in their own right rather than controls, and the tier is complete.

Projects

A Gantt chart, a PERT chart and a task board over one plan, scheduled by the critical-path method against a working calendar. Drag or type any change and the other two views follow; ten thousand tasks scroll like ten.

Reports

A report designer and a report viewer, both entirely in the browser: drag fields onto bands, group and total them, and see real pages that print or save as a tagged PDF — no report server. Fifty thousand rows lay out without freezing the page.

Logs

A log and audit viewer that opens a million lines in the page: JSON, logfmt, syslog, access logs, CSV and plain text, searched by field and by pattern, with personal data masked. Nothing is uploaded; follow a live stream as it arrives.

Canvas

An infinite canvas for working together: sticky notes, shapes, frames, connectors and your own HTML on a board without edges. Ten thousand items pan and zoom smoothly, and every change comes out as JSON for your multiplayer server.

Grids

A data grid for business applications — a million rows that scroll smoothly, fifty column types, editing with validation and undo — and a multi-dimensional pivot grid with slicers and a pivot chart, totalled in the browser on a background thread.

Formulas

A spreadsheet's calculation in the page — over four hundred Excel functions, dynamic arrays, names and tables, recalculating only what a change touches — and a formula bar with colouring, completion and argument hints. Excel files open and save, formulas and all.

Scheduling

A resource scheduler for rooms, people and equipment: drag to book, clashes and capacity checked as you go, repeating bookings, working hours in each resource's own time zone, utilisation, a finder for free time, and .ics files both ways.

Forms

Forms drawn from JSON with the library's own fields — sections, repeating rows, pages with a review step, conditions, calculations and checks in a safe expression language, and a server's errors against the fields.

A form designer builds them by dragging fields onto pages.

Charts

Twenty-two kinds of chart drawn by the library with no charting package — columns to sankey, time axes in any time zone, zoom, a million points — and a sparkline the size of a word. Every value read by the keyboard and in a table.

Editors

A rich text editor with nothing loaded from anywhere: a slash menu, mentions and Markdown as you type, comments and tracked changes, clean paste from Word, and HTML, Markdown or JSON out.

Chat

The conversation for an AI assistant or a support desk: answers streamed as they arrive, code, tables, sources and tool steps, files, stop, retry and rate. It holds no model and sends nothing anywhere.

Imaging

A picture editor that sends nothing anywhere: crop, straighten, adjust, annotate and redact for good, and save — with the photo's location, camera and owner removed before it leaves the page.

Diagrams

A designer for flowcharts, processes in swimlanes and network diagrams: connectors that route themselves, automatic arrangement, Mermaid in and out, and changes as operations for editing together.

Spreadsheets

A whole spreadsheet in one element: toolbar, formula bar, sheet tabs and the keyboard your users know, over 406 Excel functions. Excel files open and save with their formulas, formats and colours, all in the page.

Code

An editor with twenty-six languages coloured, several cursors, find and replace, folding, problems and suggestions, and a diff side by side or in one column, with revert and accept. Both stay quick at a million lines.

Queries

A query builder for filters and rules: AND, OR and NOT in groups, typed fields and 28 comparisons, written out as SQL for six databases, MongoDB, OData or JsonLogic, as a filter for records in the page, or as a sentence.

Dashboards

Dials, bars and bullet graphs with bands, targets and the change from last time, and a layout of tiles your users drag, resize and keep. Gauges can be set by the reader, as form fields.

Maps

The world built in, coloured by your figures, with markers that group when they crowd, great-circle routes, four projections, zoom and a table view. No tiles and no map service; your own GeoJSON works too.

Networks

A network graph for people, payments and services: five layouts, communities and key connectors found for you, shortest paths, a time bar, groups that combine and open, and an overview. Usable at ten thousand nodes.

Timelines

Moments and spans in rows that nest, from millennia to milliseconds: drag to move and resize, items that stack and cluster, any time zone, and a navigator with a histogram. Fifty thousand items stay smooth.

Files

A file manager over your own storage: a folder tree, details or tiles, search and a preview, new folders, rename, cut, copy and paste, drag and drop, uploads and downloads, each checked by the page first.

Barcodes

Code 128, EAN, UPC, ITF, Data Matrix and PDF417, QR codes with rounded or dotted modules and a logo, a signature pad that goes into a form, and a field for hand-held scanners and the camera.

Steppers

A task in steps — a checkout, a set-up, an import — with a step list that shows what is done and what needs attention, Back and Next that check each step first, and “Step 2 of 5” on a phone.

Documents

A PDF viewer with its own PDF engine: zoom, rotation, find, thumbnails, the outline, links, comments and form fields, password-protected files, print and download. Thousands of pages open at once.

Commands

A command palette: Ctrl + K, a few letters, Enter. Actions, pages and your own records found together, initials understood, shortcuts that work anywhere, and choices that open on their own page.

Tours

A product tour round any screen: a card beside each part, the rest dimmed, steps that wait for the reader to try the real control, tours that branch, and your page's say before each step.

Properties

A property grid for designers and settings: the right editor for every kind of value, nested objects and lists, several objects edited at once, rules that refuse bad values, undo, and editors of your own.

Permissions

A permissions matrix: roles across, resources down, allow, deny or inherit in each cell — worked out through inheritance, explained cell by cell, and reviewed by your page before anything is saved.

Importing

A data importer: CSV, Excel and JSON in, clean rows out, in the browser. Columns matched to your fields, every value checked, problems fixed in a grid, duplicates removed, and your server given the last word.

Decisions

A decision table: business rules as DMN rows, every hit policy, formulas, a trace of why each rule did or did not fire, checks for gaps and overlaps, test cases, and DMN XML in and out.

Colours

A colour picker: saturation, hue and opacity, hex, RGB, HSL and OKLCH, your design tokens as swatches, recent colours, the eyedropper, and a live contrast check that finds the nearest colour that passes.

Transfer lists

Two lists, available and chosen, and the moves between them — people to a role, columns to a report — with filters, groups, locked items, ordering, limits and a hundred thousand items.

Reviews

A review layer: comments pinned to any page, tied to elements so they follow the content, with replies, @mentions, resolve and reopen, a list with filters, and your page's say on every change.

Floor plans

Desks, rooms, seats, parking and lockers on the floor where they are: live states by colour and pattern, choosing and booking, filters, zones, floors, drawings imported from SVG, and an editor.

Workflows

A workflow designer and engine: approvals in swimlanes by role, formula conditions, time limits and escalation, a problems list and a simulator — and task cards run by the same engine as your server.

Recurrence

The "repeat" of a calendar: daily, weekly, "the last weekday of the month", ending after so many times or on a date — as an iCalendar rule or cron, in words, with the next dates in the series' own time zone.

JSON

A JSON editor with four views of one document — tree, text, table and changes — checked against a JSON Schema as it is edited, with search, go to path, undo, and edits your page can refuse.

Terminals

A terminal for shells, build logs and device consoles: full colour, the alternate screen of full-screen programs, search, links, copy and paste, and a hundred thousand lines without a stutter.

Data mapping

Two field trees and a line for every mapping: formulas, lookup tables, lists to lists, auto-map, problems and a live preview — and the same maps run in a worker or on your server.

3D models

STL, OBJ, glTF and GLB in the page: turn, move and zoom, standard views, sections, an exploded view, a parts tree, measuring, and notes pinned to the surface.

Email

An email template designer: rows, columns and blocks by drag, click or keyboard, exported as HTML that email clients draw, with a plain-text part, merge fields, a preview and checks before sending.

Planning

A planning grid for budgets and forecasts: accounts by month, quarter and year, versions compared cell by cell, totals spread over the cells below them, formula rows, what-if and sign-off.

Configurators

Configure, price, quote: choices in steps or on one page, rules that keep every combination buildable and say why, volume tiers, discounts with approval and a bill of materials.

Comparisons

A redline of two versions of a Word file, PDF, HTML, Markdown or text: changes word by word, moves and formatting, accepted or rejected one by one, with the clean copy out.

Annotation

Labelling images for machine learning: boxes, rotated boxes, polygons, skeletons and painted masks, a queue with review, model predictions, and COCO, YOLO and Pascal VOC in and out.

Media

A video and audio player with captions and subtitles, chapters, a transcript that follows along and can be searched, scrub thumbnails, bookmarks, loops and spoken descriptions.

Captions

A caption editor: captions on a timeline over the waveform, timed by dragging or by keyboard, checked against reading-speed and line rules, fixed in one step, and written as WebVTT or SRT.

Risks

A risk matrix: a heat map on your own scales with bands and appetite, inherent, residual and target scores with the arrows between them, and the register beside it.

Reconciliation

Two lists of money matched by rules, one to one, one to many and many to many, with confidence, review, adjustments, ageing of what is left and sign-off by a second person.

Time series

Millions of points from sensors, meters and metrics in stacked panes: zoom and pan, an overview, thresholds, events, anomalies, an earlier period behind, and live data.

Signing

Prepare a PDF for signing and sign it in the page, signer by signer, and get the original back with every value stamped on it and a signing certificate at the end.

Rostering

A shift roster: shifts painted, typed or dragged into place, labour rules checked as you go, cover by the hour, and auto-fill that says why it could not fill a gap.

Notifications

The bell and the inbox behind it: notifications by day, stacked, pinned, snoozed until later, muted by source and searched, or drawn in place as an activity feed.

Filters

Faceted search for any list: counted checkboxes, ranges with a histogram, dates, ratings and switches, keywords, chips, saved views and the choice in the address bar.

APIs

An OpenAPI or Swagger description as documentation and a console: every operation tried with its parameters checked, the answer checked against its schema, and samples in four languages.

Mind maps

A mind map built from the keyboard or an outline beside it: four layouts that never overlap, colours, folding, notes and links, and OPML, Markdown, PNG and SVG out.

Processes

Process mining from an event log: the map of how work really flows, the longest waits, a replay, variants, every case, and conformance against the way it is meant to go.

Tracing

A distributed trace from OpenTelemetry, Zipkin or Jaeger: the timeline in its call tree, the critical path, a flame graph, the service map and two runs compared.

Lineage

Where data comes from and where it goes: column-level tracing, impact analysis with the owners to tell, and PII carried downstream wherever it lands.

Docking

Panels in tab groups that split, float, fold to an edge and maximise, docked with guides or from the keyboard, the arrangement saved as JSON.

Galleries

Grid, masonry or justified rows for thousands of pictures, with a lightbox that zooms, swipes, compares before and after and plays video.

Panoramas

360-degree pictures and virtual tours: hotspots from room to room, a floor plan that follows you, auto-rotate and a tour editor.

Labels

Shipping labels, shelf labels and asset tags bound to data, on sheets or rolls, printed at real size or exported as PDF and ZPL.

Profiling

What is in every column and what is wrong with it: types, outliers, patterns, personal data, rules checked and drift since last month.

Drivers

A result broken into its drivers, with what-if sliders, scenarios, goal seek, a sensitivity tornado and a plan-to-actual bridge.

Audio

A multitrack editor with loudness, silence removal and a spectrogram - and call recordings with card numbers and keypad tones bleeped.
