Self-Hosted Apps Built with Python

51 self-hostable apps built with Python you can run on your own server — compared on specs, deployment difficulty, and the SaaS each one replaces.

AI Agent Platforms

AgentArea

A self-hosted runtime for governed agentic networks: instead of an agent library you import into your own app, AgentArea runs agents durably as infrastructure, with VPC-style network isolation between them, tool-approval workflows, ReBAC authorization, and full audit trails. Built on Temporal for durable execution, provider-agnostic via LiteLLM, and extensible through hosted MCP servers.

changedetection.io

Watches web pages for content changes and sends notifications through Apprise to Discord, Slack, Telegram, email, webhooks and more, with CSS/XPath/JSON filters to limit a watch to part of a page. Plain HTTP fetching works out of the box; JavaScript-heavy pages need an optional Playwright/Chrome browser container.

AI Agent Platforms

Dify

A platform for building LLM applications — chatbots, agents and multi-step workflows — in a visual editor, with a built-in RAG pipeline over your own documents and connectors for many model providers. Its modified Apache 2.0 license forbids running it as a multi-tenant service or removing the Dify logo from the web frontend without a commercial license.

ERPNext

ERPNext is a GPL-3.0 open-source ERP from Frappe covering accounting, order management and inventory, manufacturing, asset management and projects, built on the MIT-licensed Frappe Framework. There is no paid edition of the software — Frappe sells managed hosting (Frappe Cloud), not features. HR and payroll live in a separate GPL-3.0 app, Frappe HR. It self-hosts through the official frappe_docker stack: MariaDB, two Redis instances, the web backend, background workers, a scheduler and a websocket service.

Frappe CRM

Frappe CRM is an open-source CRM built on the Frappe framework (the same platform behind ERPNext), with a Kanban deal pipeline, call and email integrations, and a low-code UI builder for custom fields and views. It installs via the frappe_docker bench pattern — a MariaDB and Redis stack alongside a container that provisions the site.

Glances

A terminal system monitor in the lineage of top and htop, folding CPU, memory, disk I/O, network, sensors and container stats into one adaptive view. It can also serve a web UI and REST API, but it reports on the machine it runs on — it is a system monitor, not a hosted uptime service.

PostHog

An all-in-one product analytics suite: event and funnel analytics, session replay, feature flags, A/B experiments, surveys, error tracking and a SQL data warehouse behind one SDK. The self-hosted 'hobby' deploy puts the whole platform on one server, about 36 containers including ClickHouse, PostgreSQL, Redpanda (Kafka-compatible), Redis, Elasticsearch, Temporal and Caddy; PostHog's docs ask for 4 vCPU, 16 GB of RAM and more than 30 GB of storage. Self-hosting is free-plan features only, with no support and no tagged releases. The code is MIT, except the ee/ directory, which is under PostHog's proprietary enterprise licence.

Saleor

A headless, GraphQL-first commerce platform: products and variants, multi-channel and multi-currency selling, checkout, orders, warehouses and promotions, run from a React admin Dashboard. The stack is a Python and Django API, Celery workers, PostgreSQL and a Redis-compatible cache; it ships the API and Dashboard, not a customer-facing storefront, so you build or adopt one against the GraphQL API. The API and the Dashboard are both BSD-3-Clause.

Sentry

The full self-hosted edition of Sentry's error tracking and performance monitoring: exceptions, stack traces, releases, alerts, tracing, session replay and profiling, using the same SDKs as the hosted product. The upstream self-hosted repository is a Docker Compose blueprint of about 50 containers (Kafka, ClickHouse, Postgres, Snuba, Relay and more) licensed under the Functional Source License (FSL-1.1-Apache-2.0) — source-available, converting to Apache 2.0 after two years — and it needs 4 CPU cores and 16 GB of RAM at minimum.

Business intelligence

Apache Superset

An Apache Software Foundation data-exploration and dashboarding platform: write SQL in a browser editor or build charts without code, assemble them into dashboards, and connect to a wide range of SQL databases. It is a Python (Flask) backend with a React frontend that keeps its own state in a metadata database, and the full feature set also needs a Redis cache and Celery workers. Upstream's Docker Compose setup is for trying it out; its recommended production route is Kubernetes.
