What's new

XeLaTeX is now available on the free plan, long sessions stay logged in without a page reload, and the editor gets a visible search button alongside the existing Ctrl+F shortcut. Plus incident resolved emails so you hear back when an outage ends.

• ImprovedFree plan now includes XeLaTeX — most real-world LaTeX documents use Unicode or system fonts and previously failed to compile on free
• FixSessions no longer expire silently after 24 hours — a 401 now triggers a silent token refresh and retries the original request transparently
• NewSearch button added to the editor breadcrumb bar — opens the find & replace panel without needing to remember Ctrl+F
• FixIncident resolved emails now send when an admin marks an incident as resolved — previously only the opening notification was delivered

FormaTeX is now a first-class tool for AI assistants. The Model Context Protocol server exposes three tools — compile_latex, list_engines, and get_usage — so Claude, Cursor, Cline, and any MCP-compatible agent can compile LaTeX without writing a single API call.

• NewPublished formatex-mcp — a full MCP server for AI assistant integration
• NewThree MCP tools: compile_latex, list_engines, get_usage
• NewClaude Desktop support via claude_desktop_config.json configuration
• NewWorks with Claude Desktop, Cursor, Cline, and any MCP-compatible coding assistant
• DocsNew /mcp page with setup walkthrough and example AI prompts

Long documents no longer require your HTTP client to wait. Submit a job, get a job ID, poll for status — or register a webhook URL and get notified on completion. Powered by Redis and Asynq with two parallel workers.

• NewPOST /api/v1/compile/async — submit jobs and receive a job ID
• NewGET /api/v1/jobs/:id — poll for compilation status and retrieve the PDF
• NewWebhook support: register a callback URL per job for push notifications
• InfraTwo parallel Asynq workers running in Docker Compose
• InfraRedis 7 job queue with automatic retry on transient failures
• ImprovedDashboard now shows async job history alongside sync compilations

Two new engines expand what you can compile. LuaLaTeX brings embedded Lua scripting and OpenType font access. latexmk auto-detects the number of compilation passes required — no more manually chasing cross-references.

• NewLuaLaTeX engine: Lua scripting, modern font engine, full Unicode support
• Newlatexmk engine: auto multi-pass compilation, BibTeX and Biber support
• ImprovedXeLaTeX cold-start latency reduced ~40% via font cache pre-warming
• FixFixed edge case where xelatex dropped the last page on complex multi-section documents
• InfraWorker Docker images updated to TeX Live 2024

The new /dashboard/usage page gives a full picture of your compilation activity: monthly totals, engine breakdowns, success vs. error rates, and average compile times. The X-Compile-Duration-Ms response header is now included on every compile response.

• NewNew /dashboard/usage page with monthly compilation breakdown
• NewEngine-by-engine percentage bars (pdflatex / xelatex / lualatex / latexmk)
• NewX-Compile-Duration-Ms header on every /compile response
• NewPlan limit progress bar with hard-block and soft-block states
• ImprovedAPI key page now shows last_used_at timestamp per key
• FixFixed usage period reset not aligning with billing cycle on plan upgrade

FormaTeX launches publicly. Send LaTeX, get PDF. No TeX Live installs, no version conflicts, no infrastructure overhead. A single POST endpoint handles the rest — sandboxed, rate-limited, and production-ready from day one.

• NewpdfLaTeX and XeLaTeX compilation via POST /api/v1/compile
• NewAPI key management: create, revoke, and delete keys per user
• NewThree paid plans: Pro, Max, Entreprise — plus a free tier (15 compilations/mo)
• NewSandboxed TeX Live workers: -no-shell-escape enforced, network-isolated
• NewRate limiting: Redis-backed per-IP and per-key throttling
• NewBilling via Polar.sh: hosted checkout, customer portal, webhook support
• InfraFull Docker Compose stack: Nginx, Go API, workers, PostgreSQL 16, Redis 7
