Not your average paste bin.
CodeThis is a fast, minimal paste and code-sharing service for developers — 100+ languages with syntax highlighting, rich MDC components for docs-grade pastes, and an MCP server so AI assistants like Claude can create pastes directly from chat. Free tier includes the REST API + MCP; Pro at $9/mo adds password-protected pastes, unlimited documents, and premium image export.
Everything you need
Rich Markdown with Custom Components
Go beyond plain text. Use MDC syntax to embed alerts, steps, code groups, and more — all rendered beautifully.
# Welcome ::alert{type="info"} Beautiful MDC components. :: ::steps 1. Write markdown 2. Embed components 3. Ship it ::
100+ Language Syntax Highlighting
From JavaScript to Rust, Python to YAML — every language gets full syntax highlighting powered by CodeMirror.
const greet = (name) => { return `Hello, ${name}!` }
Organize with Folders
Group your pastes into folders and collections. Keep your snippets organized the way your brain works.
📁 work ├─ api-notes.md └─ deploy.sh 📁 snippets └─ regex.txt
Share Links or Invite Users
Copy a public link or invite specific people by email or username. Invitees land on the doc the moment they sign up — no friction, no account-seat math.
Password Protection (Pro)
Add a password to sensitive pastes. Only people with the password can view the content. Available on Pro.
API & MCP Server
Integrate CodeThis into your workflow with our REST API or use the MCP server with AI assistants.
# REST API POST /api/pastes { "content": "...", "language": "js" } # MCP Server claude → codethis.dev/mcp
Instant Screenshots
Turn any paste into a share-ready screenshot with macOS/Windows/terminal window chromes, gradient backdrops, and 8 syntax themes. Export as PNG or WebP. Premium gradients on Pro.
MDC makes docs beautiful

How CodeThis compares
Honest head-to-heads with the other tools developers reach for — feature matrices, clear trade-offs.
vs
GitHub Gist
Git-backed snippets under your GitHub identity.
If you need Git-grade version history on a snippet, Gist wins. For everything else — rich markdown & MDC, anonymous sharing, password protection, real expiration controls, and an MCP integration your AI assistant can actually use — CodeThis is built for it.
vs
Pastebin.com
The original pastebin, in ~2008 form.
Pastebin is what you used in 2008. CodeThis is what a pastebin should look like in 2026 — clean editor, rich markdown, MDC components, modern OG previews, and an API that isn't walled behind a "Pro" upsell on every page.
vs
Carbon.now.sh
Turn code into a beautiful PNG.
Carbon turns code into a picture. CodeThis turns code into a URL — and also a picture, right inside the Image tab on any paste. Two outputs, one tool.
