+Three SaaS platforms for tracking projects, tasks, and data. Each has a REST API for programmatic access.
+
+## Choosing a Platform
+

+| Software issue tracking | **Linear** | Fast, keyboard-driven, GraphQL API |
+| Knowledge base + databases | **Notion** | Pages, wikis, databases, rich content |
+| Forms and data collection | **Airtable** | Built-in forms with submissions |
+| Engineering workflows | **Linear** | Sprints, cycles, project boards |
