FoldRender guide
Open HTML files, alongside the rest of your repo
This is the shortest guide in the set, and deliberately so: HTML support in FoldRender is a small, sharply bounded feature, and padding it out would mean inventing capabilities. It opens a .html file from the file tree in a fenced-in viewer. Here is exactly what that viewer does — and, more usefully, what it will not do, because that is the part that decides whether it is any use to you.
FoldRender is on the Play Store as FoldRender: Git Repo Reader, package id dev.foldrender.app, free and distributed worldwide. Install it the ordinary way — no allow installs from this source prompt to approve, and updates arrive on their own. The app declares minSdk 30, so it needs Android 11 or newer; Play will tell you if a device is below that rather than letting you install a build that cannot run.
Open the .html file
From a workspace: tap the row in the Files tab — HTML files are badged HTML. From outside the app: choose Render in the “Open with” list, since FoldRender registers for text/html, application/xhtml+xml and the .html extension. Detection also falls back to content, so a file whose first non-whitespace bytes are <!doctype html> or <html> routes here even without the extension.
Read it, and zoom if you need to
The page renders in a WebView with JavaScript and content access disabled; file access is on only for a file in a clone, so its sibling stylesheets and images can load. Pinch-zoom controls are enabled without the on-screen zoom buttons, so you can scale a page laid out for a desktop width. The magnifier opens the find bar over the page's text, and Export or share in the ⋮ menu hands the page on with its relative images inlined.
Expect links to leave, not navigate
Every navigation attempt is intercepted and handed back to the app rather than followed in place. This is a viewer for one file, not a browser you can click around inside.
How FoldRender handles it
One file, no browser
This is the WebView that shows your files, and it is fenced in on purpose: no JavaScript, no content access, file access only for a file in a clone, and every link handed back to the shell. FoldRender is a document reader, and a general-purpose browser is a different product with a different threat model.
Useful for what it is useful for
Self-contained HTML — an exported report, a coverage summary, a single-file documentation page, or an export FoldRender itself produced with everything inlined — opens from the repository tree without leaving the app.
Where HTML sits among the formats
It is one of fifteen renderers, chosen by score over name, MIME type and magic bytes. Markdown, source, PDF and notebooks are the formats verified on a clean device; HTML is described here from the shipped implementation.
What does FoldRender not do?
The honest list — shipped-but-unverified behaviour included, so you can tell before installing whether this build does the thing you came for.
What this page says about the current app was read from its source on 2 November 2026. The same day, the then-current release, built from its tag, was walked signed out on two cloud phones (Galaxy S26 on Android 16, Pixel 9 on Android 15): it cloned a public repository, edited and saved a file, made a local commit with push off, and opened 16 file types, none of them source code. Not part of that run, among other things: push, Sign in with GitHub in the browser, cloning a private repository, PDF search and passwords, HTML find, export, deleting a clone, the diff viewer, and fold and unfold on real hardware. Clean-device results on this page are from an earlier pass, on an earlier build.
Relative references resolve only in a clone. A file in a repository FoldRender cloned loads with its folder as the base URL, so a sibling style.css or img/ directory works. A file opened through the system picker has no folder behind it, so the same page renders as unstyled markup. A sibling script.js never runs.
JavaScript is disabled outright. Anything that builds its content at runtime shows nothing.
No history, no tabs, no address bar, no cookies, no page-to-page navigation. Links are handed back to the app instead of being followed.
How does FoldRender compare with the other ways to read a repo on Android?
Four apps people actually reach for, and the one axis that separates them: whether the repository ends up on the phone, and whether anything renders it once it is there.
Prices are for the download. GitHub Mobile’s capabilities follow your GitHub plan; Termux and MGit are both free software. MGit’s version and date are from its F-Droid listing.
What are the numbers behind FoldRender?
Every figure here is read out of the shipping build or off a primary source listed at the foot of this page — nothing is rounded up for effect.
Price: US$0 on Google Play, distributed worldwide. There is no billing library in the build, no subscription and no paid tier to upgrade to.
Current release: the version the Google Play listing shows. This page does not repeat the number, which would be wrong between a release and the next site update. The app's figures here were last checked against its source on 2 November 2026.
Android floor:minSdk 30 — the API level Android 11 shipped with in 2020 — compiled and targeted against API 36.
Highlighting: 65 languages recognised across 89 file extensions, applied lexically to the whole file.
Reading limits: a single file is read up to 32 MB and then flagged truncated; workspace grep skips files over 1.5 MB and stops after 500 matches rather than flooding the pane.
Reference device: the Galaxy Z Fold 7, launched in 2025 — an 8-inch inner screen, 8.9 mm folded, and a 4,400 mAh battery Samsung rates at up to 24 hours of video playback.
The lineage: Git has been public since 2005, so the on-disk format this app reads is 21 years old; Samsung shipped the first Galaxy Fold in 2019, giving Android 7 years of real foldable hardware to target.
The toolkit: the UI is Jetpack Compose, whose 1.0 shipped in 2021, on an OS that has had split-screen multi-window since 2016.
FAQ
Can FoldRender open HTML files on a foldable?
Yes, in a deliberately limited viewer: JavaScript off, content access off, file access only for a file in a clone, links handed back to the app rather than followed. It renders the markup in the file itself.
Why does my page look unstyled?
Because it was opened from outside a clone, with no folder behind it, so relative references to a stylesheet or image next to the file cannot resolve. Open it from a repository FoldRender cloned and they do. HTML with everything inline renders as intended either way, and a script never runs.
Is it a browser?
No, and not accidentally. There is no address bar, no tabs, no history and no JavaScript, and every navigation is intercepted and returned to the app. It is a viewer for one file.
Can I search inside an HTML file?
Yes. The magnifier opens the find bar over the page's text.
What is it actually good for?
Self-contained HTML in a repository: exported reports, coverage summaries, single-file docs — including the self-contained HTML that FoldRender's own export produces, which inlines fonts, math, diagrams and images as data URIs.
How much does FoldRender cost?
US$0. It is free on Google Play, distributed worldwide, with no billing library in the build, no subscription and no paid tier.
Which Android versions does FoldRender run on?
Android 11 and newer. The app declares minSdk 30 — the API level Android 11 shipped with in 2020 — and is compiled and targeted against API 36. It is developed and tested on a Galaxy Z Fold 7, which launched in 2025.
Does FoldRender work offline?
Yes, once a repository is on the device. Cloning needs the network; reading, searching, and rendering Markdown, source, PDFs and notebooks out of a clone or a picked folder do not. Signing in to GitHub is optional and only matters for private repositories.
How is this different from GitHub Mobile, Termux or MGit?
GitHub Mobile reads repositories hosted on GitHub and does not clone to the phone. Termux and MGit both clone and then leave rendering to you — Termux gives you a shell, MGit ships no text editor at all. FoldRender clones over HTTPS and renders what it clones, on the inner screen.
Where can I check these claims?
The primary documents behind the figures above, so you can confirm any of them without taking our word for it.
