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.

Typewise AI Customer Service launched on Product Hunt April 23, 2026 as the company's pivot from AI text prediction (its original product) to a full agentic customer service platform. The new offering deploys orchestrated AI agents that integrate directly with CRM, ticketing, and e-commerce systems to resolve customer requests end-to-end — not just suggest replies, but actually close tickets. The architecture is multi-agent by design: a routing agent classifies inbound requests, specialized domain agents handle returns, billing, technical support, or order tracking, and a quality assurance agent reviews responses before they go to customers. Integrations include Zendesk, Salesforce, Shopify, and Intercom. The company claims response rates of 85%+ autonomous resolution, with human escalation for edge cases. Typewise targets mid-market e-commerce and SaaS companies spending $50K-$500K annually on support operations. The shift from AI-assisted (humans with autocomplete) to AI-autonomous (agents with escalation) is the decisive move the market has been building toward — Typewise is betting it's arrived. With 125 upvotes on Product Hunt and enterprise customers already announced, this is one to watch in the increasingly crowded AI support space.
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 multi-agent routing architecture is the right call — a single model trying to handle all support types inevitably underperforms specialists. The Zendesk and Salesforce integrations mean zero new infrastructure for most enterprise buyers. This is a serious production-ready contender.”
“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.”
“Every AI support company claims '85% autonomous resolution' — but the definition of 'resolved' matters enormously. Does a ticket closed by an agent count if the customer replies unhappy? The actual CSAT impact of fully autonomous support is still deeply unclear, and unhappy customers caught in agent loops can do real brand damage.”
“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.”
“Customer support is the first massive-scale profession that autonomous agents will actually replace, not just augment. Typewise's end-to-end resolution approach is the right architectural bet. The companies that deploy this aggressively in 2026 will have a structural cost advantage that compounds for years.”
“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's run Shopify stores, the idea of agents that can handle returns, exchanges, and order questions without me writing a single reply is genuinely life-changing. The brand voice consistency concern is real, but Typewise's QA agent layer addressing it is the right design call.”
