Everything you need. Nothing you don't.

\feature{editor}

A full IDE. In the browser. No installation.

FormaTeX ships a complete LaTeX development environment that runs entirely in the browser. CodeMirror 6 with LaTeX syntax highlighting, a resizable split-pane PDF preview, a project file explorer, outline panel, symbols list, minimap, and a full compilation log with parsed error list. Upload images, .bib files, and custom class files. Autosave triggers every 1500ms — closing the tab loses nothing.

• Split-pane: LaTeX source left, live PDF preview right — drag to resize
• File explorer with folder support (.tex, .bib, .cls, .sty, images)
• Outline panel extracts section headings from source automatically
• Full compilation log + Problems panel with parsed error and warning list
• Keyboard shortcuts, word count, minimap — all configurable

\feature{collaboration}

Multiple people. One document. Live.

WebSocket-based real-time collaboration shipped in February 2026. Invite collaborators by email, assign Editor or Viewer roles, and see live presence indicators with colored avatars derived deterministically from each user's UUID. Viewers are restricted server-side — they cannot broadcast edit events regardless of client state. Opening the same project in two tabs evicts the older connection automatically.

• Invite by email — Editor or Viewer role per collaborator
• Live presence: colored avatars consistent across sessions
• Viewer restriction enforced server-side, not just in the UI
• Duplicate-tab eviction: older connection automatically closed
• 3 / 6 / 15 collaborators per project (Pro / Max / Enterprise)

\feature{templates}

Send JSON. Get PDF. No LaTeX knowledge required.

Define a LaTeX document once as a template, mark dynamic values with {{variable}} placeholders, and expose a compile endpoint that accepts plain JSON. Your callers never touch LaTeX — they POST a JSON object with variable values and receive a PDF. Templates support uploaded assets (logos, .bib, .cls files), forking for new variants, and are callable with any API key.

• {{placeholder}} variable schema with type definitions and default values
• POST variables as JSON → receive a compiled PDF directly
• Upload template assets: logos, bibliography files, class files
• Fork any existing template as a starting point for a new variant
• 0 private templates (Free) → 25 (Max) → 999 (Enterprise)

\feature{github}

Push your project to GitHub. Pull from any repo.

Link any FormaTeX project to a GitHub repository and keep them in sync. Push your LaTeX source, .bib files, and assets to a branch with one click — or trigger a push automatically after every successful compilation. Pull changes from GitHub to restore a previous version or onboard a new collaborator's fork. Works with public and private repositories. Available on Max and Enterprise plans.

• Connect any project to a public or private GitHub repository
• Push on demand or automatically after every successful compile
• Pull from any branch — restore, fork, or onboard from existing repos
• Full file tree synced: .tex, .bib, .cls, .sty, images, and assets
• Available on Max and Enterprise plans

\feature{rest-api}

Send LaTeX. Get PDF. One endpoint.

The entire FormaTeX compilation surface is a single POST endpoint. No SDK required, no authentication ceremony. Send JSON containing your LaTeX source and engine preference, receive a binary PDF in the response body. Every response includes compilation timing, engine used, and your remaining quota in the headers. Works identically from curl, JavaScript, Python, Go, or any HTTP client.

• No SDK required — any HTTP client works in any language
• Binary PDF returned directly in the response body
• Compiler log included in 422 error responses for debugging
• X-Compile-Duration-Ms, X-Engine, X-Compilations-Used on every response

\feature{async}

Blocking, background, live-streamed, intelligent, or multi-file. Pick your mode.

Five compilation modes for every use case. Sync returns the PDF immediately in the response — zero setup. Async enqueues the job and returns a job ID in under 10ms — no connection held open, ideal for batch pipelines. Stream delivers log output line-by-line via SSE as the engine runs — perfect for live progress UIs. Smart compile reads your document preamble, selects the right engine automatically, and retries on transient failure. ZIP compile accepts a full multi-file project archive — thesis, book, CV kit — and returns the compiled PDF in one request.

• Sync: PDF in response body — one round-trip, zero polling
• Async: job ID returned instantly, poll GET /jobs/{id} for result
• Stream: live SSE log output — build a real-time terminal in your UI
• Smart: auto-selects engine from preamble, retries on transient failure
• ZIP: POST a .zip with main.tex + assets, get the PDF back — no project required

\feature{equation-render}

Any math string. PNG or SVG. No full document needed.

Send a raw LaTeX math expression, get back a sharp PNG or SVG image — no document preamble, no boilerplate. The API wraps it in a standalone document automatically, compiles with pdflatex, and converts to your preferred format. amsmath, amssymb, and amsfonts are pre-loaded. Separate from the compilation quota — equation rendering never counts against your monthly limit. Ideal for chat apps, edtech platforms, documentation tools, and anywhere math needs to display.

• Send math content only — no \documentclass, no \begin{document} needed
• Inline mode ($...$) or display mode (\[...\]) via a single boolean field
• PNG at any DPI from 72 to 600 — or SVG for resolution-independent output
• Binary image response by default; JSON + base64 via Accept: application/json
• Does not consume your monthly compilation quota
