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.

Cenote deploys AI sales agents that automatically reach out to customers who abandoned checkouts, churned from subscriptions, or went quiet after a demo. The agents communicate across SMS, voice calls, email, and WhatsApp — meeting customers on whatever channel they respond to — without requiring engineering work to set up. YC-backed and founded by Kofi Ansong, Cenote targets D2C brands and subscription businesses where cart abandonment rates typically run 70-80%. The multi-channel approach is the key differentiator: most recovery tools are pure email, but SMS and voice conversion rates often run 3-5x higher for high-intent shoppers. The platform claims live deployment in under a week. The economics are compelling — recovering lost revenue from already-acquired customers is the highest-ROI activity in e-commerce, and AI agents can personalize outreach at scale in a way that traditional blast campaigns can't. Launched today on Product Hunt with 80+ 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.”
“The no-engineering-required claim is the right call for D2C brands — Shopify operators are not developers. Multi-channel orchestration (pick up on WhatsApp if SMS is ignored) is legitimately hard to build yourself. If the conversation quality is good, the ROI math is easy to justify.”
“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.”
“AI-powered cart abandonment outreach is a crowded space — Recart, Postscript, Attentive, and a dozen YC companies have been here for years. Voice calls for abandoned carts risk serious consumer backlash and run afoul of TCPA regulations without careful opt-in management. Cenote needs to show real conversion lift data, not just launch metrics.”
“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.”
“Cenote is an early example of AI agents being deployed where the economic incentive is clear and measurable — revenue recovery. As AI agents get better at genuine conversation, the entire customer success and sales re-engagement category will be transformed. The ones building the data advantage now will be very defensible.”
“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.”
“For creator-run e-commerce brands where the founder IS the brand voice, Cenote's AI agents could be trained to sound authentically like the brand — something generic email blasts never achieve. The WhatsApp channel is particularly interesting for international creator commerce where email open rates are dismal.”
