Stuffle Labs designs and operates foundational software systems.
We build infrastructure for planning, identity management, developer communication, and documentation. Our systems are designed for long service life, offline capability, and predictable behavior.
What We Build
Core domains
Planning & Organization
Structured systems for capturing, organizing, and tracking work across teams and projects. Offline-capable and hierarchy-aware.
Identity & Access
Authentication, authorization, and tenant management infrastructure. Designed for self-hosted deployment and long-term operational stability.
Developer Communication
Programmatic messaging infrastructure with SDKs, webhooks, and delivery guarantees. Built for integration, not marketing.
Documentation & Knowledge
Systems for authoring, searching, and maintaining technical documentation. Local-first editing with optional semantic retrieval.
Product Portfolio
Current offerings
Offline-first planning and boards for organizing work across projects and teams.
Identity and access management bundle for self-hosted teams. Authentication, sessions, tenant boundaries.
Developer-first email and messaging platform with SDKs, webhooks, and operational dashboards.
Markdown-first documentation system with semantic search and local editing.
Architecture & Philosophy
How we build systems
Offline-first by default
Core functionality operates without network connectivity. Data is stored locally. Sync is additive, not required. Users retain access to their work during outages.
Separation of concerns
Application logic, data storage, and AI inference are isolated. Each concern has dedicated boundaries. No hidden dependencies between layers.
AI as gated capability
AI features are opt-in and explicit. Inference passes through a policy layer with quotas and audit logging. AI never acts without user confirmation.
Long service life
Systems are designed for years of operation. Backward compatibility is protected. Breaking changes require migration paths. Stability over velocity.
Company
Operating principles
Local-first as a design constraint
Control over convenience
Explicitness over magic
Stability over velocity
Predictable behavior over automation
Precise language over marketing
