Cal.diy is a community-maintained fork of Cal.com with all enterprise and commercial code stripped out — no Teams, no Organizations, no Insights, no SSO/SAML, and crucially, no license key required. Everything works out of the box under a pure MIT license. The goal is a truly self-hostable, zero-commercial-strings scheduling platform for individuals and small teams who don't need enterprise features but do need full data ownership. The technical stack is unchanged from Cal.com: Next.js, React, tRPC, Prisma ORM, and Tailwind CSS, with support for Google Calendar, Outlook, Daily.co video, email notifications, and standard event type booking flows. The project effectively resolves the "open core trap" by maintaining a clean split: if you want enterprise features, pay Cal.com. If you want a completely free, auditable, no-vendor-lock scheduling system, Cal.diy is the answer. With 41.5k stars (inherited from the Cal.com fork lineage), it has massive visibility. The maintainers are explicit that this is best suited for advanced self-hosters with server admin experience, not a one-click deploy for non-technical users. But for developers who want scheduling infrastructure without SaaS dependencies, it's arguably the cleanest option available.

Google Workspace Studio

Google Workspace Studio is a no-code platform that lets business users build and deploy AI agents across Gmail, Docs, Sheets, Drive, Meet, and Chat by describing what they want in plain language. It began rolling out to Workspace Business, Enterprise, and Education customers starting March 2026, with broader general availability through April. The core experience is conversational: describe an automation like "every Friday, ping me to update my project tracker" and Gemini creates and deploys the agent. More complex agents can connect to third-party apps including Asana, Jira, Mailchimp, and Salesforce via prebuilt connectors, webhooks, or Apps Script. No YAML, no flow diagrams, no IT ticket required. Workspace Studio is Google's counter to Microsoft Copilot Studio and OpenAI's Workspace Agents — a recognition that the next wave of AI adoption will be driven by non-technical workers who need automation power without engineering overhead. If it delivers on its "describe it and it's done" promise, it could make bespoke AI workflows a standard expectation for every knowledge worker on a Workspace plan.
Reviewer scorecard
“The open core model has always been a tension with Cal.com — features gated behind enterprise licensing in a supposedly open-source project. Cal.diy resolves that cleanly. The stack is familiar, the MIT license is genuine, and for anyone building a product that needs scheduling infrastructure, this is the right starting point.”
“The Apps Script escape hatch is what makes this actually useful for builders. You can start with natural language for simple automations and drop into code when you need custom logic — that's the right design for a no-code tool. Happy to recommend this to non-technical stakeholders.”
“This is a maintenance burden in disguise. You're now responsible for keeping a large, complex Next.js codebase patched, secure, and up-to-date with upstream Cal.com changes — changes that may or may not land in the DIY fork on any predictable schedule. For most teams, Cal.com's free tier or Calendly is simply less operational overhead.”
“This 'describe it and it's done' framing always sounds better than the reality. Complex multi-step workflows built by non-technical users tend to break in unexpected ways, and support options for debugging a Gemini-generated agent are unclear. Also: you're locked into the Google Workspace ecosystem completely.”
“Scheduling is increasingly the integration surface AI agents use to take real-world actions — booking meetings, blocking time, managing availability across workflows. Having a fully controllable, self-hosted scheduling layer that AI agents can write to without SaaS rate limits or webhook restrictions is a genuine infrastructure advantage for agentic systems.”
“Google distributes Workspace to 3 billion people. When AI agent building becomes a standard feature of every Gmail account, that's not a niche developer tool — it's a civilizational shift in how knowledge work gets done. The long-term implications of every office worker having a personal automation layer are enormous.”
“For content creators or solopreneurs who just need a Calendly replacement, self-hosting a full Next.js stack is overkill. The UX of the base Cal.com is fine but not exceptional, and the enterprise features you're losing (like organization-level insights) are actually useful for managing content calendar coordination across a team.”
“As someone who lives in Google Docs and Gmail, the ability to wire up a 'summarize and reply to client emails' agent without involving a dev is exactly what I've wanted for years. The Jira and Asana connectors mean it fits into actual creative agency workflows too.”
