Self-Hosted Apps Built with Svelte

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

Low-code internal tools

Budibase

A low-code platform for building internal apps, forms and admin panels on your own data, with an internal database plus connections to external SQL and REST sources, and a builder that publishes apps to end users. The monorepo is GPL-3.0 overall, the paid packages/pro package is under the Business Source License, and the packages that ship inside built apps are MPL-2.0; the all-in-one Docker image bundles CouchDB, Redis, MinIO and nginx.

Hu

Project Management

Huly

An open-source business-application platform whose self-hosted build combines project management with chat, CRM, HR and recruiting apps. The official docker compose setup is heavy: it runs nginx, CockroachDB, Redpanda, Elasticsearch, S3-compatible object storage and a set of Huly services, and upstream sets a minimum of 2 vCPUs and 8 GB of RAM. The code is EPL-2.0. The platform README says hosted Huly has shut down and that the hcengineering/platform repository is frozen, with development continuing in Platform-Collective/platform, so self-hosting is the way to run it.

Monitoring

Kener

A status page system: public pages fed by uptime monitors, with incidents, maintenance windows, alerting and role-based team access, so your users can see what is up and what is not. MIT-licensed, built with Node.js and Svelte; it needs Redis for its queues, cache and scheduler and stores its own data in SQLite by default (PostgreSQL or MySQL via DATABASE_URL).

No-code database

Mathesar

A spreadsheet-like web interface that works directly on PostgreSQL databases, schemas and tables, with access control built on Postgres roles and privileges, a data explorer for queries and a form builder.

AI Chat Interfaces

Open WebUI

Feature-rich, self-hosted ChatGPT-style interface for Ollama and any OpenAI-compatible API, with built-in RAG, model management, and multi-user support. The web UI itself is lightweight; pair it with a GPU-backed Ollama backend for local model inference.

Workflow automation

Windmill

A code-first developer platform that turns scripts in Python, TypeScript, Go, Bash, SQL and more into webhooks, scheduled jobs, flows and internal UIs — the self-hostable alternative to Retool, Pipedream and Temporal rather than a Zapier-style connector catalogue. The core is AGPL-3.0 and the free Community Edition has no execution cap, but it is capped at 50 users and lacks SAML/SCIM, Enterprise-grade audit logs, autoscaling and the forms/prompts layer of approval steps, and the shipped CE image also contains proprietary code.
