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.

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.

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.

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

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.

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

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 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.

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.

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.

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

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

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.

Anthropic pulled Claude Code from its $20 plan and reversed course within days, but the signal matters more than the reversal. Every major AI tool is sold below cost. When subsidies end, every workflow built on rented AI becomes a cost you didn't budget for or a capability you lose overnight.

AI didn't break the code; it broke the economics. Hallucinated bug reports, spam pull requests, and a verification tax are overwhelming unpaid maintainers. Projects are closing their gates. If your stack depends on open source, upstream project health is now a board-level concern.
