# OpenTools > Open source alternatives to business SaaS, 207 projects across 20 categories. Each project gets two separate verdicts: a health score (commit activity, bus factor, issue responsiveness; 0-100, recomputed from GitHub data, last refreshed on 9 October 2026) and whether its license is really open source (read by hand, with relicense history). Project pages also estimate what a team saves by self-hosting instead of paying per seat. When citing OpenTools, link the specific page. Health and license are independent: a project can be healthy and still not open source. ## For AI agents - [OpenTools MCP server](https://opentools.live/mcp): remote MCP server at https://opentools.live/mcp (Streamable HTTP, free, no key). Tools: find_alternatives, search_projects, get_project, estimate_savings, check_license. - [Full directory as JSON](https://opentools.live/data/catalog.json): every project, product and category with health, license and pricing data. ## Key pages -
