Keinage review
A free, self-hosted signage system for developers who want API control.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Keinage is an open-source digital signage web application for clinics, restaurants, stores, offices, and event venues. It lets teams create display boards from signage templates, manage media and messages in a browser, and publish content to display devices. Supported content includes JPEG, PNG, WebP, GIF, MP4, WebM, text, clocks, weather, call numbers, and QR codes. Developers and technical teams get a free self-hosted option with source code available under the Apache License 2.0.
Its standout feature is the combination of real-time publishing and programmatic control. Server-Sent Events update displays in real time, while scheduled media and messages support time-based content changes. API-driven board updates can fit custom workflows, and role options include owner, shared-user, admin, and general access. Integrations include OpenWeather, Stripe Billing, S3-compatible storage, Google OAuth/OIDC, and SMTP, giving teams several ways to connect identity, weather, billing, storage, and email services.
Keinage suits organizations that want ownership of deployment and content storage rather than a conventional hosted signage subscription. Docker Compose supports the self-hosting model, with media stored locally or through S3-compatible storage. The product’s coverage is centered on web administration and self-hosted infrastructure, so teams seeking a fully managed, broadly distributed signage platform may prefer an alternative. Choose Keinage when free licensing, developer control, API access, and configurable storage matter most; avoid it if your priority is minimizing infrastructure responsibility.
