Lovable for your terminal.

Every ask ships inside a design brief. Direction before code, design tokens over one-off styles, and a ban list of the patterns that make pages read as machine-made. Seven committable aesthetic directions, or write your own.

The dev server is watched. Fresh build errors go back to the engine with the surrounding output and a root-cause instruction, capped at two attempts.

The page itself is checked. After each clean turn squint loads the app headlessly and catches what the server never prints: blank pages, exceptions, hallucinated CSS classes, invisible focus, text that vanishes in high-contrast mode, buttons real translations will truncate, retained DOM after journeys, dark-pattern tells, and janky frames — attributed by function.

The agent looks at its own work. Screenshots at phone, tablet, and desktop widths, then a critique of what it can actually see, ranked by visual impact, then fixes.

Drift gets named. Every clean turn is screenshotted, compared with the last, and the changed regions hit-tested against the live page — the pulse says which element moved, not just a percentage. On kitty, Ghostty, WezTerm, or iTerm2 the screenshot renders as real pixels inside the transcript. LCP deltas and long-frame jank ride along, attributed by function.

Evasion gets caught. Deleted tests, added skips, suppression comments, watered-down checks, touched locks — detected deterministically each turn and reported to you, never sent back to the engine that did it. Decisions live in a committed ledger the engine cannot silently undo; contested changes pause for your /yes or /no.

The session outlives the terminal. The daemon owns the run on a unix socket; attach the full TUI from any terminal or over ssh. Teammates get observer seats; the driver seat passes on detach. A dropped connection no longer kills the work.

A second reviewer, a standing goal. The review lane reads each turn's diff in fresh context — blind spots don't inherit. /goal arms a machine-checked objective: auto-fix presses until squint's gates come back clean, because the engine doesn't get to decide when it's done.

Two more doors in. squint ci runs the whole loop headlessly in a pipeline — gates, page audit, flow replay, JSON report, honest exit code, and a digest-sealed receipt tying green to the exact pixels. squint mcp serves the gates as MCP tools, so agents that speak MCP call squint instead of squint wrapping them.

Reversible and explorable. Every ask records a checkpoint, so undo and rewind are one command. Sandbox mode stages whole sessions in a shadow worktree until you apply. Variants build the same ask three ways in parallel. Alt+S pins elements with notes and compiles them into one annotated ask.
