What each one is good at
OpenClaw Skills
Built around its core job, OpenClaw Skills stays out of your way. Spec: 1 vCPU, 1 GB RAM, 15 GB disk. It tops the table for a reason: the install flow here is one click, and the first hour costs cents.
Context7
Teams pick Context7 when they need the basics done well. Plan for 1 vCPU and 2 GB of RAM. If the top pick feels heavy, this is the usual alternative.
GBrain
GBrain covers the essentials without demanding a manual. Plan for 1 vCPU and 2 GB of RAM. Newer to the catalog, climbing steadily.
Playwright MCP
Teams pick Playwright MCP when they need the basics done well. Spec: 1 vCPU, 2 GB RAM, 25 GB disk. Lesser known, often a better fit for smaller teams.
Choosing a server
Every app in this list runs on our Pay as you go plan. The heaviest spec here wants 1 vCPU and 2 GB of RAM — about €0.023 per hour, billed only while the server is on. Each app page shows its recommended plan.
