RUN Native app runner · R + Python

Run any R or Python app in a real window — deps and all.

Apptrope opens Shiny, Streamlit, Gradio and eight more frameworks in a genuine native window — not a browser tab — and resolves each app's dependencies into its own isolated environment. Point it at a folder, a Git repo, or a signed bundle. It handles the rest.

One window. Eleven ways to build.

Apptrope runs the R and Python web frameworks people actually ship — dashboards, notebooks, model demos — each in its own native window. Shiny runs in both languages.

Real apps, in a real window.

Not mockups — every one of these is a live app running inside Apptrope, its dependencies resolved with rv or uv into an isolated environment. All eleven supported frameworks, captured running: Shiny in both R and Python, Streamlit, Gradio, Flask, Panel, Voilà, Marimo, Dash, Bokeh, and Solara.

Dependency resolution

Point it at an app. It handles the deps.

Every app gets its own isolated environment — no global installs, no version conflicts, nothing on your machine touched or required. Apptrope resolves R packages with rv, Python packages with uv, and provisions a portable R toolchain through micromamba.

rvResolves and locks each R app's package set.

uvResolves each Python app's dependencies, fast.

micromambaProvisions a portable R with no system install.

App sources

Bring an app from anywhere.

Load an app from wherever it lives. Apptrope reads it, resolves it, and runs it — no repackaging, no manual setup.

Local folder A project directory on your disk.

Archive A zip or tar of the app.

Git repo GitHub · gist · GitLab · Bitbucket.

Archive URL A direct link to a zip or tar.

.apptrope bundle A signed, shareable app file.

Signed bundles

Share an app your users can actually trust.

Package any app into a single .apptrope file — signed, tamper-evident, and safe to hand to anyone. Every byte is covered by SHA-256 integrity and signed with an Ed25519 author key. Recipients pin your publishing key once; after that, your apps launch without a prompt.

Trust on first use

Pin a publisher's key once. Every app they sign after that launches with no prompt — like an app store you curate yourself.

Key rotation with continuity

Publishers can rotate signing keys across multiple hops without breaking the trust their recipients already granted.

Revocation

A local revocation list plus shareable revocation certificates, so a compromised key can be pulled from circulation.

Hardened by design

Integrity is verified before anything launches. Extraction is guarded against path-traversal and twin-manifest attacks, and secrets never travel inside a bundle.

Made for the classroom

Hand students one signed .apptrope file. They open it and it runs — verified, dependencies resolved into an isolated environment — with no setup and no “works on my machine.”

The workbench

Built to run several things at once.

Apptrope is a workbench, not a single-shot launcher. Keep a shelf of apps, run a few side by side, and read exactly what each one is doing.

TabsMulti-tab runsRun several apps side by side, each in its own tab and environment.

LibraryApp libraryKeep apps with their metadata and search across everything you've added.

LogsPer-run logsFull output for each app, captured live while it runs.

SecretsKeychain-backed envPer-app environment variables and secrets, stored in the OS keychain — never in a bundle.

ThemeAdaptive light & darkFollows your system and stays legible in either mode.

Deep linksNative URL schemeOpen and run an app from anywhere with apptrope://.

Inside the app

A workbench, not a black box.

Run several apps at once, read their logs, manage their secrets, and control exactly who you trust — all in one native window.

The Apptrope workbench: a searchable library of R and Python apps shown as cards — Your workbench — every app you've run, saved and searchable

The Confirm-before-running dialog with integrity and signature status — Trust on first use — integrity checked, publisher shown

The Trusted Publishers panel: identity, rotate key, revocation certificates — Identity, key rotation, and revocation in one place

The environment-variables editor with masked secret values — Per-app secrets, stored in your OS keychain

The per-app actions menu: open, rename, environment, export bundle, view logs — Manage, export, and inspect every app
