Your agent writes YAML. The compiler ships HTML.

A declarative page compiler for coding agents: short Page Spec in, one deterministic, offline, accessible HTML file out.

Write meaning, not markup

90 block types in eight categories: layout, content, data, interaction, media, showcase, engineering and product. Semantic blocks like hero, timeline, kpi, data-table, chart, kanban and pricing carry the design for you.

✓ Verified claim:https://github.com/bestagentkits/ak-render#find-the-blocks-you-need

One file, zero network

Every page is a single self-contained HTML file with embedded fonts and icons. It opens from file://, makes no requests by default, and ships nonce-locked styles and script.

✓ Verified claim:https://render.agentkit.best/

Same spec, same bytes

Compilation is deterministic: the same spec and compiler version produce an identical file and hash, so diffs and caches stay meaningful.

✓ Verified claim:https://github.com/bestagentkits/ak-render#readme

Fewer tokens per page

Benchmarked presentation context drops 64 to 68 percent against AgentKit's legacy HTML guidance; a typical page task is estimated at 17.9k tokens instead of 38.9k.

✓ Verified claim:https://github.com/bestagentkits/ak-render#token-cost

Validate with JSON-path diagnostics

`ak-render validate --json` returns stable codes and the exact JSON path to fix, so an agent can repair a spec in one pass instead of guessing.

✓ Verified claim:https://github.com/bestagentkits/ak-render#validate-and-fix

Data, state and themes as data

Bind charts and tables to declared datasets, drive views from page state, pick from typed theme presets, multi-pack icons and named motion recipes. Pages still read completely with scripts off.

Find and describe blocks

`ak-render catalog` or `search-catalog` finds the blocks you need; `describe --compact` returns one line per prop. Start from a recipe like dashboard or implementation plan.

Validate the spec

`ak-render validate plan.yaml --json` reports every problem with a stable code and JSON path. Fix and retry until it passes.

Compile one file

`ak-render plan.yaml --out plan.html` writes a self-contained page and prints bytes, hash and runtime features. Remotely, render returns an artifact URL instead.

Built with AgentKit

AgentKit Engineer
AgentKit produces a lot of HTML: plans, explainers, diffs, recaps. Every one was hand-written by a model, which meant paying for layout and CSS on every page and getting a slightly different page every run. AK Render started on 2026-09-20 with the Page Spec v1 schema and a simple bet: let the model describe meaning, let a compiler own presentation. 0.1.0 shipped to npm on 2026-09-22; 0.2.0 polished the emitted pages; 0.3.0 added composition, data widgets, recipes and the remote MCP server. Since then it gained icons, an editorial broadsheet layout, in-page plan review and Motion Studio. It is built with AgentKit and benchmarked against AgentKit's own ak:preview HTML route.

What's shipped

  1. Motion Studio, a local motion inspector (opens in a new tab)

    `ak-render motion studio <spec>` serves a local dashboard to preview, tune and accept motion recipes, writing the reviewed diff back to the spec.

  2. Motion discovery and deterministic motion audit (opens in a new tab)

    List and search motion recipes, and audit a spec or compiled page for unguarded, looping or never-playing motion with CI gating.

  3. Broadsheet layout engine and newspaper preset (opens in a new tab)

    An editorial broadsheet layout engine with a newspaper theme preset.

  4. Multi-pack icons with theme profiles (opens in a new tab)

    Lucide, Phosphor, Tabler, Pixelarticons and Codicons, chosen by meaning through theme icon profiles and embedded only when used.

  5. Review a plan inside the page

    New decision and feedback blocks let readers comment on a plan in the rendered page, plus compile-time syntax highlighting.

  6. Remote MCP accepts OAuth and API keys (opens in a new tab)

    The hosted MCP server at render.agentkit.best accepts AgentKit OAuth sign-in or a personal API key.

  7. v0.3.0: composition, data widgets, recipes and remote MCP (opens in a new tab)

    Rich composition, data widgets, page recipes and the remote Streamable HTTP MCP server, with every 0.2.0 spec still valid.

  8. v0.1.0 published to npm (opens in a new tab)

    The first release of @bestagentkits/render: Page Spec v1, validation and a deterministic offline compiler.
