Which tool should you pick in 2026?
Short answer: if your problem is too many calendars, pick manyCalendars. If your problem is too many tasks, Sunsama deserves a look.
Sunsama is a daily planning app. It helps you decide what to work on today by pulling tasks into your calendar through a guided morning ritual. manyCalendars is a calendar aggregator.

What is Sunsama, and what does it do well?
Sunsama is a guided daily planner. Each morning it walks you through a short ritual: review yesterday, pull in today's tasks, estimate how long each will take, and timebox the day onto your calendar. It connects to task tools like Todoist, Asana, Trello, and Notion, plus email and Slack, so you can turn messages into planned work.
Credit where it is due. The design is calm, the daily ritual genuinely helps people who struggle to start the day with intention, and the apps are polished across web, desktop, and mobile. If your core problem is focus rather than fragmentation, Sunsama earns its following.
What does manyCalendars do differently?
manyCalendars skips the ritual entirely. It does one job: take every calendar you have and merge them into a single view with color coding and conflict detection, in month, week, or day layout. No tasks, no journaling, no morning ceremony. Open it, see your whole week across every client, get back to work.
It is also local. The free tier needs no account. Events are read in your browser and stay in your browser. There is no manyCalendars cloud for your meeting titles to sync through.
The free tier covers unlimited calendars you add manually. Pro unlocks browser-tab calendar sync (Tab Sync) for calendars IT will not let you export, meeting notifications, a work week view, and .ics export. Premium adds Privacy Mode, cross-calendar conflict detection, auto-block busy-mirroring, and share-availability on top of everything in Pro.
Which is cheaper, manyCalendars or Sunsama?
Sunsama costs $22 per month, or $17 per month billed annually, which comes to $204 per year. There is no free plan.
manyCalendars starts at $0, and the free tier is a real product, not a teaser: unlimited calendars you add manually, merged into one private view with month, week, and day views and color coding. Pro is $15 per month, or $150 per year, which works out to $12.50 per month. So to be fair: Sunsama is more expensive every way you slice it, and only manyCalendars offers a $0 tier at all.
Two options Sunsama does not have. Premium is $29 per month, or $290 per year, and adds Privacy Mode, cross-calendar conflict detection, auto-block busy-mirroring, and share-availability. And teams and agencies can put every seat on Team at $39 per seat per month, or $390 per seat per year ($32.50 per seat per month, minimum 2 seats), with delegation access for an assistant, shared busy policies, and centralized billing.
Which is better for privacy?
Sunsama is a cloud product. You connect calendars and task tools via OAuth, and your data syncs through Sunsama's servers so everything stays consistent across devices. That is normal for the category, and for someone with one employer it is usually a reasonable trade.
manyCalendars is 100% local. Your calendars are read and merged on your device, there is no cloud sync, and the free tier does not even ask for an account. If you are a consultant holding calendars for three clients, some under NDA, that difference is not cosmetic. With a cloud planner, your combined schedule, client names, meeting titles, and working patterns sit on someone else's infrastructure. With manyCalendars there is no server to breach and no third party to trust.
Can either one show a locked-down corporate calendar?
This is where the gap is widest. Sunsama reaches calendars through OAuth, which means the account's tenant has to allow third-party app access. Many corporate environments block exactly that, and a contractor is the last person IT will make an exception for.
manyCalendars Pro includes browser-tab calendar sync. If you can see the calendar in a browser tab, manyCalendars can read it. No OAuth grant, no admin rights, no IT ticket. For client calendars you can view but cannot export or connect, this is often the only approach that works at all.
So who should choose which?
Choose Sunsama if you have one primary calendar, you want a structured daily planning ritual, and you live in task tools like Asana or Todoist. It is a thoughtful product for that workflow, and the cloud trade-off is reasonable when only one organization's data is involved.
Choose manyCalendars if you are a contractor, consultant, fractional executive, or any multi-client professional whose real problem is five calendars in five tabs. You get pure aggregation without a planning ceremony, a free tier to start on, a cheaper annual price, support for calendars IT has locked down, and the only privacy model in this comparison where your clients' data is read and merged on your device, not in our cloud.
The free tier takes about a minute to set up and never asks for an email address. Install manyCalendars for free and stop pretending your brain can do what a calendar tool should.
