sher.sh

What It Is

sher is a developer tool for generating temporary live preview URLs for frontend projects. Its positioning is very clear: you don’t need Vercel or a GitHub repository to quickly turn a project into an accessible link. The page also specifically mentions build and deployment workflows for AI agents — “AI agent builds it, sher links it” — suggesting that it is more of a lightweight temporary preview layer than a full cloud deployment platform.

Core Features

Based on the captured content, sher’s core capability is creating temporary preview links. Links expire automatically, and uploaded files are automatically deleted after the link expires. Usage is CLI-oriented: you can install it with npm i -g shersh, or try it in a project without installation via sh <(curl -fsSL sher.sh/run) link. The Free plan requires no account. The Starter plan allows users to list and delete links after signing in via GitHub OAuth, while Pro adds password-protected links. The text does not specify which frontend frameworks are supported, whether there is an API/SDK, whether it is open source, or whether self-hosting is supported.

Pricing and Limits

Pricing is straightforward: Free costs $0 and includes 1 link per day, a 6-hour TTL, and a 10MB limit; Starter is free via GitHub and includes 25 links per day, a 24-hour TTL, and a 50MB limit; Pro costs $8/month and includes 200 links per day, a 7-day TTL, a 100MB limit, and support for password protection. Pro is billed monthly through Polar and can be canceled at any time, but partial-month refunds are not provided. Overall, it is well suited for short-term previews, but not appropriate if you need long-term hosting or production-grade SLAs.

Pros and Cons

The main advantages are that it is extremely easy to get started, requires no repository or platform configuration, and is suitable for quickly sharing a frontend demo with others. Pricing is simple, and even the free tier can cover low-frequency usage. The drawbacks are also clear: the official terms state that availability or uptime is not guaranteed, so it should not be relied on for permanent hosting; there are hard limits on link count, TTL, and file size; and the captured text provides limited information about documentation, framework compatibility, enterprise features, and security details.

Who It’s For and Access from China

sher is suitable for indie developers, frontend engineers, hackathon projects, and scenarios where an AI Agent generates a page that needs to be previewed and shared. The captured text does not provide information about access from mainland China. Payments are handled through Polar, and availability of domestic Chinese payment methods is also unknown. If you need stable production deployment or optimized access from China, alternatives such as Vercel, Netlify, Cloudflare Pages, GitHub Pages, and Surge may be worth considering.
