Routebase
Routebase GmbH
Routebase is the single source of truth for your APIs. Design your OpenAPI spec once in a visual editor — no hand-edited YAML — and your documentation portal, mock servers, contract tests, and monitoring all derive from that one spec. Change the contract, publish, and Routebase catches what drifted before your consumers do: it validates live responses against the spec and flags every divergence with field-level diffs — missing fields, type mismatches, undocumented additions. Work on specs the way you work on code: branch, review, merge, with breaking-change detection before anything ships. Publish a docs portal on your own custom domain. Spin up realistic mocks so frontend and backend build in parallel. Run contract and security tests against any environment. Every workspace also ships a built-in MCP server, so your AI agents read and act on the same source of truth, under your team's permissions — no glue code.Starting Price: $9/month/user -

2sync
2sync
2sync is a cloud sync platform that keeps records consistent across the tools a team already runs. It connects Notion databases with Google Calendar, Outlook Calendar, Todoist, Google Tasks, Google Contacts, Outlook Contacts, Gmail and Outlook Mail. Calendars, tasks and contacts sync in both directions: create or edit a record in either system, and the change appears in the other within minutes. Gmail and Outlook Mail sync one way into Notion, turning business correspondence into a searchable database. Every field is mapped individually and set to sync both ways, only into Notion, or only out to the connected app. Filters control scope by calendar, priority, label, status, or any Notion property. Relation databases are supported, so attendees link to a contacts database and tasks link to projects. Teams share a connection so members sync their own calendars into one shared Notion database. Sync runs as often as every 2 minutes. Previously known as Notion Automations.Starting Price: $7/month billed annually -
