Sell it as a service

A platform for building automations and AI agents by dragging steps onto a canvas and connecting them, with the option to drop into JavaScript or Python for the parts a visual editor handles badly. It connects to more than 1,500 services and ships over 9,000 ready-made workflow templates, and it can call OpenAI, Anthropic, Google or open-weight models interchangeably. The same workflows can include branching logic, tool use, human approval steps and monitoring, so a prototype and a production automation are the same artefact. You can run it yourself with Docker or use the hosted version.

Who to offer it to: Small teams connecting sales, support, and finance apps

Sample offer: Install and harden a self-hosted n8n workflow, then document one business automation.

Example price: €300 setup source

License or service note: SUL permits paid consulting and client-server installs; hosting n8n as a service, white-labeling, or client editor access needs a commercial license.

Scan or upload bills, receipts and contracts and turn them into an archive you can search by any word inside them. Paperless-ngx is for people who want to keep less paper and run that archive on their own server. It runs OCR (optical character recognition, reading text out of scanned images) with the Tesseract engine, then uses machine learning to suggest tags, correspondents and document types. It is the community-supported successor to Paperless and Paperless-ng, and a public demo at demo.paperless-ngx.com (login demo/demo) lets you try it first. The docs say Tesseract recognises more than 100 languages.

Who to offer it to: Small offices with paper invoices, receipts, and records

Sample offer: Install Paperless-ngx as one app with HTTPS, a first backup, a runbook, and access handoff.

Example price: From $79 single-app install source

License or service note: GPL-3.0; review its terms before distributing modified copies.

A development platform built around Postgres, the long-established open-source database. Alongside the database it gives you the parts most applications need next and usually build badly: sign-in and permissions, automatically generated REST and GraphQL APIs over your tables, live subscriptions that push changes to connected clients, serverless functions, file storage, and a toolkit for vector embeddings. The project’s stated approach is to assemble it from existing enterprise-grade open-source tools wherever they exist and to open-source the pieces it has to build itself.

Who to offer it to: Small software teams that want their Supabase project on a server they control

Sample offer: Migrate Supabase to self-hosted infrastructure as a scoped project, including technical assessment and migration planning.

Example price: From €3,490 excluding VAT source

License or service note: Apache-2.0 for the repository, with individual components under their own licenses; commercial use is permitted subject to each component’s terms.

A self-hosted chat application that puts a single interface in front of many model providers at once — OpenAI, Anthropic, Google, AWS, DeepSeek and others — so switching models does not mean switching product. It supports agents you configure and share, MCP tools, skills, file search, code execution and artifacts. Recent releases add a public API for managing agents programmatically, per-agent workspaces where an agent can inspect a file tree and run commands with time limits, and a trace viewer that shows a conversation as an ordered sequence of steps, tool rounds and cost.

Who to offer it to: Small teams that want a managed AI chat interface hosted in Germany

Sample offer: Install and operate LibreChat in a dedicated, GDPR-compliant German hosting environment with updates, backups, and monitoring.

Example price: From €99.90 net/month source
