What it is
SkySend is an open-source service for sharing files and encrypted notes without accounts. Its homepage makes the security model part of the visual hierarchy: a centered headline emphasizes the privacy promise in green, a short explanation sits directly beneath it, and a terminal card shows the self-host command before the page expands into features, automation and setup.
When to open it
Use it as a reference for explaining a technical trust property in a product landing page, or when you need an example of a self-hosted utility that offers both a web UI and scriptable access.
Most useful
- Hero: states the task and privacy guarantee in one sentence, then gives documentation and source-code paths equal prominence.
- Copyable install command: the Docker command makes self-hosting tangible before visitors reach the longer guide.
- Trust explanation: separate sections explain client-side encryption, the URL fragment key and standard algorithms.
- Automation section: CLI, TUI, REST API and CI use cases are presented as parallel ways to access the same service.
- Feature list: describes file/note types, expiry, download limits and storage choices in plain language.
Using it with agents
SkySend documents a cross-platform CLI and a REST API that each self-hosted instance exposes. These are usable from agent workflows and CI; the docs cover commands and endpoint behavior. There is no public MCP server or llms.txt listed on the homepage.
Watch out for
- Client-side encryption and URL-fragment key handling are security claims; assess the implementation and threat model in the repository before relying on them.
- Public instance limits vary. The page distinguishes public servers from self-hosting, so check the chosen instance before sharing files.
- The AGPL-3.0 licence applies to the project code; the brand and marketing artwork are not a general-purpose asset library.
Reusable ideas
- Put the first practical command in the hero when self-hosting is the product's key promise.
- Explain a security property as a short sequence of user-visible facts rather than a wall of cryptographic terms.
- Show browser, command-line and API access as sibling paths under one service.
- Pair trust claims with links to documentation and source code.
