Self-Hosted Apps Built with Next.js

18 self-hostable apps built with Next.js 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.

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.

Observability

Langfuse

An open-source LLM engineering platform: traces for LLM calls and agents, prompt management and versioning, evaluations (including LLM-as-judge), datasets and a playground. Its SDKs and OpenTelemetry ingest feed a Postgres + ClickHouse + Redis + S3-compatible-storage stack, so it is a real multi-service deployment, not a single container.

AI Chat Interfaces

LobeHub

An AI chat and agent workspace, formerly LobeChat, that connects to OpenAI and many other model providers and supports plugins. The self-hosted server edition keeps its data in PostgreSQL, with Redis and S3-compatible storage (RustFS) alongside. Its community license is Apache-2.0 based, but distributing derivative works needs a commercial license.

Web analytics

OpenPanel

An open-source web and product analytics platform that pitches itself as "the power of Mixpanel with the ease of Plausible": funnels, cohorts, user profiles, session history and replay, A/B tests, revenue tracking, real-time dashboards, and SDKs for web, iOS/Android and server-side events — cookieless. Licensed AGPL-3.0; the documented install clones a dedicated git branch, a setup quiz writes .env, and a start script brings up seven containers (Caddy, PostgreSQL, Redis, ClickHouse, API, dashboard, worker). Free to self-host with unlimited events, per its pricing page.
