The collaboration sheet for coding agents
The sheet passed back and forth between you and your coding agents.
Your agent publishes a plan, report, or architecture diagram as a link. Open it anywhere, mark it up by pen or text, tap choices, or talk right on the page. The agent reads every decision back into context.

The Closed Loop
Publish. Review. Decide. Read back.
No more lost context across messy terminal windows or endless chat scrolls. A single living sheet where people and agents align.
01
Publish as a link
Your coding agents (Claude Code, Codex, Antigravity) package proposals, rich reports, or diagrams into an instant, self-contained link via foldrender publish.
02
Read anywhere
Open on mobile, iPad, desktop, or any browser without requiring an account for public links. Responsive layouts, native typography, and full offline caching.
03
Mark up & decide
Circle with Apple Pencil or finger, tap options in interactive choice blocks, or talk to the agent in the sidebar right beside the page.
04
The agent reads it back
Run foldrender read or foldrender answers to bring every stroke, note, and decision back into the agent's context. The agent proceeds with clear human sign-off.
Spatial Overview
Canvases for the big picture. A desk for your inbox.
When a project spans multiple agents and artifacts, FoldRender brings them onto one spatial canvas and routes pending decisions into your desk.
Canvas: Connect related sheets
Pin multiple pages, notes, and visual connectors onto one board with foldrender canvas. Understand architecture flows, compare proposals side by side, and zoom into any card at full fidelity.
Desk: Your agent inbox
All questions, review requests, and pending decisions from background coding agents arrive at foldrender.dev/desk. Review one card, tap your answer, and send the next task into motion—all without switching contexts.
Streamlined inbox: Asks from agents queue up cleanly. Answer one by one or dismiss when resolved.

Also: A native document engine and mobile git reader.
FoldRender's foundation is a high-performance Compose document renderer. Clone a GitHub repository straight to your phone and read its code and notebooks offline.
On-device git status: On Android, cloning a public repository, editing a file in it and committing locally ran on two cloud phones on 2 November 2026. Push and the diff viewer ship in the build but are unverified, and there is no pull button.
Questions & Answers
Everything you need to know before you start.
What is FoldRender today?
FoldRender is the sheet passed back and forth between you and your coding agents. When your agent produces a plan, design, or decision, it publishes a rich page as a link (foldrender publish). You open it anywhere—on phone, tablet, or desktop—read, annotate with pen or text, tap choices, or talk in the sidebar. The agent reads all of it back (foldrender read / answers) without losing context.
How does an agent publish and read back?
Any agent can run foldrender publish <file> to get a clean link (public or private with GitHub sign-in). Later, the agent runs foldrender read <url> to fetch the page content along with human annotations and marks, or foldrender answers <url> to get structured answers to decision blocks on the page.
What platforms are supported?
FoldRender runs across platforms: Android (live on Google Play), iPhone and iPad (public beta on Apple TestFlight), Web (any modern browser at foldrender.dev/artifacts), and the CLI and Skill for agent environments. A desktop app is in development and not publicly released yet.
Is there an iPhone or iPad app?
Yes, in public beta: FoldRender for iPhone and iPad, installed via Apple's TestFlight app. It supports reading pages offline, writing annotations with Apple Pencil or finger, and publishing HTML or Markdown files via the system share sheet.
What is the status of the desktop app?
The desktop app is an Electron shell wrapping the web core via FRHost v1 with native file pickers, PDF/PNG export, and a local agent runner (ACP). It is in development and not publicly released yet: there is no download, and its source is not public.
What file types can it render?
Markdown (with tables, task lists, front matter, mermaid, LaTeX, callouts), syntax-highlighted source code, JSON, YAML, TOML, CSV, Word documents, Excel workbooks, draw.io diagrams, zip and tar archives, images, PDF, HTML, plain logs and Jupyter notebooks.
Can it actually push to GitHub from the phone?
The controls are in the build — the Describe this change field, the Push to origin checkbox and the Commit N files button. On 2 November 2026 two cloud phones edited a file in a clone and committed it with Push to origin unticked. Push was not part of that run and is unverified, so we will not tell you it works. Clone, read, edit and commit locally is the loop that has run, and there is no pull button. The git client guide lists which parts are which.
How much does it cost?
FoldRender is free, with no ads and no in-app purchases. Reading public links requires no account.
Does FoldRender work offline?
Yes. On mobile apps, pages you open are cached for offline reading and pen annotation. In the native Android repository reader, cloned repositories and opened folders render completely offline.
How is FoldRender different from Claude artifacts, Notion, or Linear?
Claude artifacts can only be viewed in a chat or shared statically. Notion is for human-written wikis. Linear tracks issues. FoldRender is specifically the interactive decision sheet between people and background coding agents: agents write the sheet, humans review and decide with pen or tap, and the agent reads the decisions back.
