Pusk — Python-first function cloud

Write Python, run it remotely. Pusk is a Python-first function/task cloud: decorate a function, call .remote(), and it executes on a self-hostable control plane — no vendor lock-in, no proprietary runtime.

import pusk

app = pusk.App("reports")


@app.function(timeout=60, memory=256)
def build_report(customer_id: str) -> dict: ...

Quickstart

pip install pusk
pusk setup --token pusk_... --api-url https://api.pusk.example
pusk run hello.py::app/greet '{"name":"world"}'

Key features

• from_name — reconnect to a deployed function by name (no import needed)
• map — fan-out parallel calls with bounded concurrency, results in input order
• Schedules — app.schedule(fn, cron="0 6 * * *") or Period(30.0) for periodic runs
• Web endpoints — @web_endpoint(method="GET") exposes a function as HTTP
• Secrets — Secret.from_name("API_KEY"); values never live in the SDK
• Image builder — Image.debian_slim() with pip fast-path and BuildKit support
• TUI — interactive terminal UI (pip install pusk[tui])
• CLI streaming — live call output streaming via pusk run

Modal parity callout

Pusk delivers Modal-like developer experience — same decorator-based DX, same .remote() / .spawn() / .map() semantics — but is self-hostable and MIT-licensed. No vendor lock-in, no proprietary runtime, no per-invocation billing from a third party. Your cluster, your code, your rules.
