Artifact Server: open-source Claude Artifacts alternative

Plannotator released Artifact Server, an open-source, self-hostable alternative to Claude Code artifacts that gives developers and AI agents a unified platform to publish, review, comment on, version, and share HTML, image, and video artifacts. The tool includes a built-in MCP server and a portable Agent Skill, supports deployment on Cloudflare, Kubernetes, AWS, Google Cloud, or locally, and requires Node.js 24.12 or newer and pnpm 10.34.3 for local runs.

The open-source, self-hostable alternative to Claude Code artifacts. Artifact Server gives people and agents one place to publish, review, comment on, version, and share the artifacts they create while building products. Its built-in MCP server gives agents direct access to the same work. Run it on a laptop for one developer. Deploy it for a private team on Cloudflare, one server, Kubernetes, AWS, or Google Cloud. Why Artifact Server why-artifact-server Built for AI agents and team collaboration built-for-ai-agents-and-team-collaboration Cloudflare and Artifact Server cloudflare-and-artifact-server Deploy it for a team deploy-it-for-a-team Run it locally run-it-locally Usage usage Security model security-model Development and project records development-and-project-records Teams now use HTML, images, and video for plans, mockups, prototypes, code reviews, and other work created during product development. That work quickly becomes disorganized, and providers try to lock it inside their platforms. Artifact Server gives teams a self-hosted place to organize and collaborate on that work. Store artifacts by project, share them, comment on them, and keep control of the files and data. Artifact Server includes a built-in MCP server and a portable Agent Skill. Agents publish and update versioned artifacts. Teams review, comment on, and share the same work. Connect the agent and install the skill: artifactserver connect npx skills add plannotator/artifact-server Then ask: /artifact-server upload that HTML design doc The agent returns the full-screen review link first. Read the MCP guide /plannotator/artifact-server/blob/main/docs/mcp.md for source checkouts, remote servers, permissions, and supported operations. Live session delivery is available from source for Pi and Claude Code Channels. Claude Channels require its research-preview development flag and, on managed plans, the organization policy. The OpenCode adapter is not release-qualified; live-host verification and contributions are welcome. Cloudflare is the main hosted deployment target. Cloudflare Artifacts can add private Git-backed history for selected projects. It is off by default and currently requires closed beta access. Deploy Artifact Server on Cloudflare /plannotator/artifact-server/blob/main/deploy/cloudflare/README.md Configure optional Git history /plannotator/artifact-server/blob/main/docs/cloudflare-artifacts.md Read the Cloudflare Artifacts documentation https://developers.cloudflare.com/artifacts/ Cloudflare is optional. Artifact Server also runs locally, on Compose, on Kubernetes, on AWS, and on Google Cloud. Every remote deployment uses one trusted application origin and one isolated wildcard content domain. | Deployment | Data layer | Guide | |---|---|---| | Cloudflare | D1 and R2 | | Compose guide /plannotator/artifact-server/blob/main/packaging/compose/README.md Compose guide /plannotator/artifact-server/blob/main/packaging/compose/README.md Helm guide /plannotator/artifact-server/blob/main/packaging/helm/artifact-server/README.md AWS Pulumi guide /plannotator/artifact-server/blob/main/deploy/pulumi/aws/README.md Google Cloud Pulumi guide /plannotator/artifact-server/blob/main/deploy/pulumi/gcp/README.md Azure teams deploy through the Helm chart on AKS; there is no separate Azure installer. Azure Blob Storage is available as a preview adapter and has not passed live Azure qualification. Read the deployment guide /plannotator/artifact-server/blob/main/docs/deployment.md for shared requirements, storage choices, authentication, and backups. Local mode stores metadata in SQLite and files on disk. It grants owner access only from the same loopback origin. Running from source requires Node.js 24.12 or newer and pnpm 10.34.3. git clone https://github.com/plannotator/artifact-server.git cd artifact-server pnpm install pnpm dev Open the printed URL. Public package download and verification commands will be added on release day. See Get started locally https://artifactserver.com/docs/get-started/ for the current source-development path. Most artifacts are published by an agent through the Artifact Server Skill /plannotator/artifact-server/blob/main/skills/artifact-server/SKILL.md or MCP /plannotator/artifact-server/blob/main/docs/mcp.md . For direct access, use the artifactserver CLI to publish files and directories, connect to remote servers, and create new versions. Read the CLI guide /plannotator/artifact-server/blob/main/docs/cli.md . Artifact Server serves untrusted artifact content from isolated version hosts, separate from the trusted application origin used for authentication, review, comments, API, and MCP. Private content uses version-scoped browser sessions, and untrusted paths cannot select storage locations.
