glim

Publish a self-contained HTML file or directory and get a short, readable link to show someone — from the command line or from a coding agent via MCP. glim runs its own server; put it behind a reverse proxy for a public URL, or use --local for a loopback link with no proxy at all.

Self-host the HTML artifacts a coding agent produces. Instead of a preview that lives on a vendor's servers, glim keeps every agent-generated page on your own infrastructure, at your own domain, under your own access controls.

Install

curl -fsSL https://raw.githubusercontent.com/samuelloranger/glim/main/install.sh | sh

Or build from source: go build -o glim .

Quick start

glim config --domain https://glim.example.com    # optional; omit for localhost links
glim serve &                                     # run the preview server
glim report.html --title "Diff review"           # -> https://glim.example.com/diff-review-a1b2/

Without a domain, links are http://127.0.0.1:PORT/.... --local auto-starts the server and returns a loopback link:

glim report.html --title "Quick look" --local

Dashboard

glim serve also serves a private dashboard at /. It shows live thumbnails of every preview and a countdown for each one, and lets you extend, pin or remove them. It updates in real time. The first visit creates the account with an email and password, so do that before exposing the server. See docs/dashboard.md.

glim version

Config

~/.glim/config.json (overridable by GLIM_DOMAIN, GLIM_BIND, GLIM_PORT, GLIM_ROOT, GLIM_TTL). A published preview lives under root until its TTL elapses; expired previews are pruned on the next command and by glim gc.

Agent integration (MCP)

glim install <agent> registers glim's MCP server (tools: present, list, revoke, pin, extend) and writes a steering rule so the agent prefers glim for previews. Supported: Claude, Codex, Cursor.

Behind a reverse proxy

Run glim serve bound where your proxy can reach it (--bind 0.0.0.0), point the proxy at HOST:PORT, and set --domain so links use the public URL. glim caddy prints a ready Caddy vhost. Keep it behind your usual access controls; a link's readable slug carries a short random suffix but is not a secret.

Run as a service

contrib/glim.service is a systemd user unit:

mkdir -p ~/.config/systemd/user
cp contrib/glim.service ~/.config/systemd/user/
systemctl --user enable --now glim
loginctl enable-linger "$USER"   # survive logout/reboot
