lfm

Looking for more. Looking for money.

lfm makes landing pages with AI agents. The agent researches real buyers, writes a design concept from what they say, and builds one HTML template with its config and assets. lfm compiles that into a standalone static folder and refuses to ship a page that is broken, slow, inaccessible, invisible to search or full of generic AI design defaults. Every finding says how to fix it.

No framework, no platform, no runtime: one binary, one page, one folder you upload anywhere.

Ask your agent

Give any coding agent (Claude Code, Codex, Cursor, OpenCode, Gemini CLI and others) this request:

Make a landing page for my sourdough course with lfm: https://lfm.cash/SKILL.md

SKILL.md tells the agent how to install lfm, set up a project and follow the process. To have every agent session pick it up by itself for requests like "generate me a landing page", install it once as a user skill:

for d in ~/.agents/skills/lfm ~/.claude/skills/lfm; do mkdir -p "$d" && curl -fsSL https://lfm.cash/SKILL.md -o "$d/SKILL.md"; done

~/.agents/skills is read by Codex, Cursor, OpenCode, Gemini CLI and GitHub Copilot; ~/.claude/skills by Claude Code. Keep only the one your agents need.

On Grok Bot, add the lfm.cash bot: it installs lfm on its own computer and runs the same process, asking you only what you decide. Its setup is in docs/grok-bot.md.

Install

curl -fsSL https://lfm.cash/install.sh | sh

The script downloads the release for macOS or Linux (amd64 or arm64), checks it against the release checksums and puts lfm in ~/.local/bin, without sudo. LFM_VERSION=v0.0.2 pins a release and LFM_INSTALL_DIR changes the folder. With Go 1.26 or newer:

go install github.com/Anonyfox/lfm/cmd/lfm@latest

Optional: Chrome or Chromium for lfm compile --release, and Lighthouse for its scores. Missing tools are reported and skipped, never installed.

Start a page

lfm init sourdough-course   # a starter project that compiles cleanly
cd sourdough-course
lfm skills install          # the process skills, where your agent loads them
lfm compile                 # findings, output/ and the next step

Then ask your agent for the page. It works in three phases, each with its own skill:

research: real buyer voices and competitor pages, verbatim and dated, into research/.
design: concept.md from the research: buyer, mechanism, direction, palette, type, imagery, motion and copy, every decision cited to a source.
implementation: the page from concept.md, until lfm compile --release is clean and every saved frame holds up on phone and desktop.

The compiler checks each handover: missing research, an uncited concept or a page that ignores the concept's palette, type and imagery show up as findings. Every report ends with the next step, such as Next (design): write concept.md from the research., and names the skill for it, so an agent working unattended stays on the path. When it says deploy, upload output/ to the URL in lfm.json.

For agents

Command	Use
`lfm`	What lfm is, how to start, every command
`lfm <command> -h`	Usage, flags and behaviour of one command
`lfm skills`	The process skills in the order a page needs them
`lfm skills <topic>`	One `SKILL.md`, rendered for the installed version
`lfm skills install`	All skills into the project's `.agents/skills` or `.claude/skills`
`lfm compile [--release] [--json]`	Check and build; the last line is the next step
`lfm serve --open`	Live preview that recompiles on every save
`lfm rules [id]`	Every check, or what one means and how to fix it

lfm skills install updates the folders that already hold lfm skills. Otherwise it writes to .claude/skills when Claude Code runs it or the project has only a .claude folder, and to .agents/skills in every other case; --agents, --claude and --global choose explicitly. Each installed SKILL.md records the lfm version and a digest of its text, so running it again after an update replaces untouched copies and keeps copies the project changed (--force replaces them too). lfm compile notes installed skills that are older than the binary.

lfm compile --json prints the result as one object with errors, warnings, the findings under validation, next (phase, do, skill) and the installed skills. Exit status is 0 when output/ was written, 1 when errors kept it unchanged or there is no project, and 2 for a mistake in the command line.

Made with lfm

lfm.cash is an lfm project in site/, built by an agent through the same three phases: 120 buyer posts and 20 competitor pages, a concept that chose one of ten directions with every decision cited, and a page that compiles with 0 errors and 0 warnings. Its proof section compiles the page an agent wrote from one sentence without lfm; that page and its report are there too.

What a compile guarantees

Correct: every template value exists and has the right shape; config mistakes point at their JSON key; links match the declared URLs; HTML parses without browser repairs.
Fast: CSS and JS are bundled and minified, small assets inlined, large ones emitted as content-named files, images sized against layout shift, HTML compacted without touching text.
Findable and shareable: canonical URL, metadata, headings, structured data and social previews are checked; preview image sizes are filled in from the real files.
Usable: controls have names, labels and focus order work, forms and disclosures behave, text keeps its contrast.
Distinct: typical generated-design defaults (stock palettes, eyebrow labels, emoji bullets, icon-card grids and more) and stock phrases of generated copy are reported, with an explicit way to keep one deliberately; the page is held to the palette, typefaces, imagery and phrases its concept.md decided.
Sellable: a Stripe Payment Link or Checkout offer shows its price, and the page links the legal pages a purchase needs.
Seen whole: --release scrolls the page at phone and desktop sizes, saves every frame and reports empty stretches, sideways scrolling, covered or unreadable text, split values and missing glyphs.
Safe to ship: nothing is written until all checks pass, and a failed compile keeps the last good output.
