Your Data has a Nationality.

Your Data has a Nationality.

A Dutch 'sovereign' cloud almost became American overnight, and only a last-minute government veto stopped it. Real digital sovereignty was never just about where your data sits. It is about whose courts can reach it, and Europe's billion-euro plan still misses the point.

Warp

Warp

AGPL terminal client around a proprietary, US-hosted AI cloud. The open part is the Rust shell; the agentic workflows, collaboration, and Zero Data Retention are paid SaaS you can't self-host.

SnapOtter

SnapOtter

AGPLv3-or-commercial image toolkit: 50+ tools plus local AI for background removal, upscaling, and OCR in one Docker container — images never leave your hardware. SaaS embedding needs a paid license.

OpenWhispr

OpenWhispr

MIT voice-to-text dictation that runs Whisper and Parakeet models fully on-device — hotkey, speak into any app, nothing leaves your machine. Cloud sync, agent mode, and SSO sit behind paid tiers.

Qdrant

Qdrant

Apache-2.0 vector database in Rust for RAG and semantic search — fully self-hostable with no copyleft strings. Multi-AZ high availability, SSO, and audit logs are gated to the managed Qdrant Cloud.

OpenHuman

OpenHuman

Local-first AI desktop assistant that keeps your "second brain" in an Obsidian-style Markdown vault and on-device SQLite. Optional local Ollama models, no cloud account. GPL-3.0, single-founder beta.

Paperclip

Paperclip

MIT-licensed control plane for fleets of AI agents — org charts, per-agent budgets, immutable audit logs, and approval workflows. The governance layer proprietary platforms paywall, here free and self-hosted.

The Digital Sovereignty Playbook

The Digital Sovereignty Playbook

Digital sovereignty projects don't fail because of the technology. They fail because someone swapped the software without rebuilding what it sits on. A four-layer framework drawn from Denmark, France, Germany, and Spain shows why the sequence matters more than the stack.

The AI models you are not using.

The AI models you are not using.

Most people stick with one AI provider because trying alternatives is friction. OpenCode Go changes that — one interface, any model. DeepSeek V4 Pro and Kimi K2.6 are delivering results that required premium subscriptions a year ago. The barrier to exploring is gone.

OpenViking

OpenViking

AGPL-licensed context database for AI agents — persistent memory, resources, and skills via a filesystem paradigm. Governed entirely by Volcengine (ByteDance); no independent foundation.

Pi

Pi

MIT-core terminal coding harness that wraps any LLM provider into an extensible agent — no IDE required. Future Fair Source and proprietary enterprise tiers announced but not yet released.

OpenSign

OpenSign

AGPL-licensed e-signature platform with unlimited document signing and PDF audit trails. Self-hosted via Docker on MongoDB — no formal compliance certifications disclosed.

Hermes Agent

Hermes Agent

Self-improving AI agent with persistent memory and autonomous skills. Now adds a native desktop app (macOS, Windows, Linux) on top of 23+ messaging channels. Self-hosted, MIT-licensed, BYOK.

Eclipse Tradista

Eclipse Tradista

Eclipse Foundation-governed capital markets platform for trade capture, P&L, and treasury operations. No licence fees or vendor lock-in — requires Jakarta EE expertise and financial data integration.

Plausible Analytics

Plausible Analytics

AGPLv3-licensed, cookie-free web analytics built in the EU. No consent banners required, sub-1KB script — SSO and automated exports gated behind the Enterprise tier.

Planka

Planka

Source-available Kanban boards with real-time collaboration and Markdown support. EU-hosted, Docker-native — but commercial hosting and cross-company use require a paid license.

OpenScreen

OpenScreen

Desktop screen recording with automatic zoom and professional effects — no watermarks, no subscriptions, no cloud dependency. Single-maintainer project.

Leantime

Leantime

AGPL-3.0 project management designed for non-project managers. Neurodiversity-aware UX with strategic PM frameworks — enterprise features gated behind proprietary plugins.

Public money, private code.

Public money, private code.

The NHS survived hostile state attacks on its open-source pandemic app with zero critical breaches. Now it ordered every team to hide their public code in one week. AI was the justification, not the reason. When a taxpayer-funded health system abandons transparency, that's a democratic decision.
