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.

Jotform launched a native Claude integration that lets users build, edit, and analyze forms directly in conversation — no separate browser tab required. You can describe what you need ("a lead capture form with conditional logic based on company size") and Claude builds it using Jotform's full feature set, including payment processing, conditional rules, file uploads, and Salesforce integrations. The integration goes beyond form creation: you can ask Claude to analyze your form submission data, spot patterns, and suggest optimizations — all within a conversational interface. For teams already working in Claude for other tasks, this removes the context-switching overhead of building forms in a separate tool. Jotform is a mature platform with HIPAA-compliant options, 17 million users, and integrations with Stripe, PayPal, HubSpot, and Salesforce. The Claude app is a smart distribution play — meeting users where they already are rather than driving traffic back to jotform.com. It debuted at #4 on Product Hunt today with 174 upvotes.
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.”
“Asking Claude to build a multi-step intake form with payment processing and auto-populate a Salesforce field — and having it actually work — is genuinely useful. This is what Claude app integrations should look like: real product capability, not a thin wrapper.”
“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.”
“Jotform has 17 million users who haven't needed a Claude integration to be productive. This feels more like a distribution experiment than a core product improvement. The conversational form builder won't replace the drag-and-drop interface for power users who know exactly what they need.”
“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.”
“Apps embedded inside AI assistants are the new distribution channel. Jotform is smart to build here — whoever owns the conversational interface owns the referral. Every major SaaS will eventually have a Claude/GPT app, and first movers get the learning curve advantage.”
“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.”
“I built a client intake form in 90 seconds by describing it in plain language — something that would've taken 15 minutes of clicking in the Jotform UI. For freelancers and small agencies, the time savings on routine form creation is real and immediate.”
