Short answer: they're built for different clinics. Juno EMR is a cloud EMR built on the open-source OSCAR EMR. It's strongest for physician-led medical clinics that need provincial billing, labs and a full medical record, and it has an API the clinic can authorize itself. Jane App is the polished all-in-one for physiotherapy, chiropractic, massage, mental health and multidisciplinary clinics, with one of the best-regarded patient booking experiences in Canada and no open API. ZeroMiss works with both, so we have no reason to push you either way.

Where Juno's open-source roots help
- Your clinic decides what connects. Because OSCAR's web services are part of the platform, a clinic and its host can enable the API and authorize a tool, rather than waiting for a vendor to approve a partnership.
- A known data model. OSCAR has been used across Canada for years, so its structure is documented and familiar to many integrators. That makes migrations and add-ons less of a gamble.
- A community beyond one company. Developers, consultants and hosts outside Juno know the OSCAR codebase, which reduces the risk of being stuck with one roadmap.
Don't over-read "open source." Juno is a hosted commercial service, its API has OSCAR-era quirks (short-lived tokens on some setups, an unreliable appointment-update call), and enabling it is your host's job. Open means possible, not effortless.
Where Jane is the stronger choice
- Patient experience. Jane's online booking, reminders and intake forms are the reason many patients prefer Jane clinics. That's hard to match.
- Built for allied health. Treatment packages, multi-practitioner scheduling, insurance billing and payments fit physio, chiro, RMT and mental-health workflows out of the box.
- Ease and support. Front-desk staff pick it up quickly, and Jane's support is well regarded.
- A careful approach to integrations. Jane's closed, vetted API is a deliberate privacy and security choice. It limits what outside tools can do, and some clinics will see that as a feature.
How to choose
If your clinic is physician-led and bills the province, Juno (or another OSCAR-based EMR) is the natural fit, and its API is a real advantage for automation. If you're an allied-health or multidisciplinary clinic and patient self-booking is central to how you run, Jane is hard to beat. If you're already on one and happy, the reception side isn't a reason to switch: ZeroMiss answers calls, texts and chats for either.
Frequently Asked Questions
Is Juno EMR open source?
Juno is built on OSCAR, an open-source EMR that started at McMaster University. The practical benefits are the OSCAR lineage: a well-understood data model, a REST API the clinic can enable and authorize, and a wide Canadian community of OSCAR developers. Juno itself is a hosted commercial service.
Does Jane App have an API?
Not an open one. Jane has said it is not launching an open, public API and that clinics cannot build their own integrations. It announced an approval-based partner program in 2026, so access goes through Jane's vetting.
Which is better for an AI receptionist?
Both work, differently. With Juno, ZeroMiss books, moves and cancels directly in the EMR after verifying the patient. With Jane, it finds real openings and sends the patient straight to that time on your Jane booking page, which is an excellent place to finish a booking.
Bottom Line
Juno gives physician-led clinics a full EMR with an open, OSCAR-derived API they control. Jane gives allied-health clinics the most polished practice and booking experience, behind a closed API. Choose for your clinical workflow; ZeroMiss will fit around either.
