Using glance.sh
What is glance.sh?
Temporary image sharing for coding agents. Paste a screenshot in the browser and get a URL your agent can fetch. No accounts.
Do I need an account?
No. glance.sh does not require sign-up and does not set cookies.
How long do images stay on glance.sh?
About 30 minutes. After expiry the image cannot be accessed, and expired blobs are permanently deleted shortly afterward.
How do I share an image without a plugin?
Open glance.sh, paste or choose an image, and copy the URL into your agent chat. The agent can curl it like any other image URL. See glance.sh.
Plugins
Do I need a plugin?
No. Plugins skip copy-paste: the agent opens a live session and receives the URL when you paste. Without a plugin, paste on glance.sh and send the link yourself. See plugin install.
How do I send a screenshot to Claude Code?
Install the glance plugin, then ask Claude Code to use the glance tool. Paste in the browser; Claude gets the URL. See Claude Code setup.
How do I send a screenshot to Codex CLI?
Install the glance MCP server, then ask Codex to use the glance tool. Paste in the browser; Codex gets the URL. See Codex setup.
How do I send a screenshot to OpenCode?
Add the glance plugin to opencode.json, restart, then ask OpenCode to use the glance tool. See OpenCode setup.
How do I send a screenshot to Pi?
Install the glance extension, reload Pi, then use /glance or ask the agent to use the glance tool. See Pi setup.
Live sessions
What is a live session?
A short-lived channel so a waiting agent can receive an image URL over SSE. You open /s/<id>, paste, and the agent gets the link. Sessions last up to 10 minutes.
Why did my live session expire?
Sessions expire after about 10 minutes of Redis TTL. Ask the agent to start glance again for a new URL. The image itself, once uploaded, still lasts about 30 minutes.
Security
Is glance.sh end-to-end encrypted?
No. Images are encrypted in your browser with AES-256-GCM before upload, but the share URL is the decryption key. glance.sh decrypts when it serves that URL. That is encryption at rest, not end-to-end encryption. See Security.
Who can see an uploaded image?
Anyone with the exact share URL, including this application, and only before the link expires. Guessing a valid link is not practical. See Security.
Limits
What image types and sizes are supported?
PNG, JPEG, WebP, GIF, and AVIF, up to 15 MB.
What does OCR do?
The OCR button on an upload card sends the image to Gemini and copies visible text to your clipboard. OCR is optional and heavily rate-limited to prevent abuse.
