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 AI Edge Eloquent
Free offline iOS dictation app powered by on-device Gemma ASR

Google AI Edge Eloquent is a free iOS dictation app released quietly on April 6 with no press announcement or Product Hunt launch. It uses on-device Gemma ASR models to transcribe speech, strip filler words, and polish raw dictation into clean prose — all without an internet connection. An optional cloud mode routes cleanup through Gemini for higher quality results. Unlike competitors Wispr Flow and Willow (both $15/month), Eloquent has no subscription and no usage caps. The app is built on the same Google AI Edge framework used in Google AI Edge Gallery, suggesting it's part of a broader push to normalize on-device LLM inference on consumer hardware. The quiet launch strategy is notable: no blog post, no social announcement, just a quiet App Store submission. This kind of stealth deployment suggests Google may be seeding on-device AI use cases without the usual hype cycle — testing user retention before investing in marketing. An Android version is widely expected given the AI Edge framework's cross-platform nature.
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 architecture here is the interesting part: Gemma ASR running fully on-device with optional cloud fallback for cleanup. This is exactly the hybrid inference pattern I'd want to build for privacy-sensitive voice apps, and Google just open-sourced the playbook by shipping it.”
“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.”
“Free with no business model and no announcement sounds more like an experiment than a product. Google has a long history of quietly killing apps that don't get traction. I wouldn't build a workflow around Eloquent until it survives at least six months in the App Store.”
“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.”
“Killing the $15/month subscription model for voice AI is a meaningful shot fired. When Google ships a free, offline-first dictation app powered by on-device models, it sets a new user expectation for the whole category. Wispr and Willow are going to have to respond.”
“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.”
“Filler word stripping plus prose polishing in a fully offline app is genuinely useful for writers and podcasters. I dictate first drafts constantly and having this work on a plane or in a dead zone without compromising privacy is exactly what I've been waiting for.”
