Self-hosting
Deploy the SmileSub subtitle system on your own server or private cloud — you keep full control of the data, with nothing to worry about
Why self-host
Data stays under your control
Video and audio are processed entirely on your internal network and never leave it. A good fit for sensitive content, trade secrets, or privacy-sensitive data.
Deep customization
Source-level customization to match your business: the UI, feature modules, API integrations, your own branding, and more.
Speech recognition can run locally
Recognition can be run locally on your own servers, so long or high-volume material does not have to be sent to a third-party cloud piece by piece. Translation can connect to a service you specify or run yourself.
Core advantages
Perpetual license, no recurring subscription fee
A one-time purchase for permanent use — no annual fee and no usage-based billing.
Runs offline
A fully local deployment: every feature works without an internet connection.
Multilingual recognition + smart translation
Recognition can be deployed with a local engine; translation covers 20 languages including Chinese, English, Japanese, and Korean, and can connect to the service you choose.
Multiple export formats
Export to mainstream subtitle formats such as SRT and VTT, ready for all kinds of editing software.
Dedicated technical support
One-to-one help with deployment guidance, training, troubleshooting, version upgrades, and more.
Scalable architecture
Containerized with Docker, so scaling clusters, load balancing, and distributed processing are easy.
