ECMA-48 vs xterm-ctlseqs vs vendor extensions
Not every escape sequence on this site is equally portable. ECMA-48 (ISO/IEC 6429, 1976) is the lingua franca — anywhere a terminal claims ANSI support, these work. xterm-ctlseqs is the de-facto second tier — every xterm-family emulator implements it, but it's not part of ISO 6429. Vendor extensions (kitty graphics, DEC sixel, iTerm2 / Windows Terminal proprietary OSCs, contour synchronized output, hyperlink OSC 8) cover the long tail where portability is per-terminal. This page sorts every sequence on the site into one of those three tiers, so you can tell at a glance what's safe to emit unconditionally vs. what needs a capability probe.
How to read this page
- ECMA-48 Defined in ECMA-48 / ISO 6429. Portable to every ANSI-aware terminal — Linux console fbcon, macOS Terminal, Windows ConPTY, every xterm-family emulator. Safe to emit unconditionally.
- xterm-ctlseqs Defined in xterm-ctlseqs (or aixterm bright-colour extension). Universally supported across xterm-family terminals (xterm, kitty, alacritty, wezterm, iTerm2, ghostty, Windows Terminal, macOS Terminal, gnome-terminal, konsole) but not on the bare Linux console or in plain VT100/VT220 hardware terminals. Safe in any modern terminal emulator.
- vendor Defined by a specific vendor or proposal: DEC's VT manuals (sixel, DECSC/DECRC), Kitty's graphics protocol, iTerm2 / Windows Terminal proprietary OSCs, the contour synchronized-output proposal, the gnome-terminal hyperlink proposal (since adopted by most). Probe before you emit, or accept that it's a no-op on terminals that don't recognise it.
Counts shown next to each tag are how many sequences in this site's corpus fall into that bucket. The per-row Spec column reproduces the citation that classifies each sequence — the same string that appears on the sequence's own page.

ECMA-48 / ISO 6429 — the portable layer
Sequences whose canonical citation is ECMA-48 (or its underlying ASCII / ECMA-6 standard for C0 controls). ISO 6429 has been frozen since 1976 in spirit and 1991 in its current published form — these sequences predate the xterm corpus and are implemented by every terminal that does anything more than dumb text output.

xterm-ctlseqs47
xterm-ctlseqs — the de-facto modern terminal layer
Sequences defined in the xterm Control Sequences reference (xterm-ctlseqs), or in aixterm's bright-colour extension that xterm-ctlseqs incorporates. These are not in ISO 6429 but every xterm-family emulator (kitty, alacritty, wezterm, iTerm2, ghostty, Windows Terminal, macOS Terminal, gnome-terminal, konsole, Konsole, Hyper) implements them. DEC private modes (?1049, ?25, ?2004, ?1004 …) and most OSC sequences live here.

Vendor / terminal-specific extensions
Sequences whose canonical citation is outside ISO 6429 and xterm-ctlseqs: DEC's VT manuals (DECSC/DECRC, sixel via VT340), Kitty's graphics protocol, iTerm2 / Windows Terminal proprietary OSCs (OSC 7 CWD, OSC 9 notifications), the contour synchronized-update proposal (?2026), the gnome-terminal hyperlink proposal (OSC 8), and the ITU-T T.416 direct-color (truecolor) extension. Practical portability varies per row — some entries (truecolor, DECSC/DECRC) are now near-universal because xterm-ctlseqs lists them as secondary; others (Kitty graphics, sixel, OSC 9) remain confined to specific terminal families. Always consult the terminal support matrix per row.
