The Best Nylas Alternatives in 2026

Nylas is one of the most popular unified API products. It offers an email API, a Calendar API, a contacts API, a notetaker API, and more.

In this article, we look at the best Nylas alternatives. We focus on platforms that cover a subset of the Nylas solutions or work as 1:1 replacements, and we include pricing and a few things to consider before choosing one.

What are the best Nylas alternatives in 2026?

1. Apiroc - For Calendar API

Apiroc is a Unified Calendar API. It gives you one API for Google Calendar, Microsoft Outlook (Office 365, Exchange, and Outlook.com), and Apple iCloud Calendar. Apiroc is a developer product only, so if you need a calendar API without the email and contacts parts of Nylas, it is a good fit.

Our team has worked with Google Calendar, Outlook, and iCloud Calendar for years and has built calendar integrations that handle billions of API calls. Apiroc is built on that infrastructure, with automatic retries, provider rate limit handling, and failover.

The Apiroc Unified Calendar API focuses on the following features:

• iCloud Calendar, Outlook, and Google Calendar integrations : Using the Apiroc Unified Calendar API, you can integrate all major calendar providers into your application using a single API. Google and Microsoft accounts connect through a hosted OAuth2 flow. iCloud accounts connect with an Apple ID email and an app-specific password through a simple API call, so no OAuth setup is needed for Apple.
• Support for webhooks : Reacting to changes in a calendar is important for most applications. That is why Apiroc supports webhooks out of the box for Google and Microsoft calendars. You register one webhook in the platform and receive signed, real-time notifications such as calendar.event.changed, no matter which of these two providers the calendar belongs to. Webhooks for iCloud calendars are planned but not available yet.
• Generic Calendar APIs : Apiroc covers End User Accounts, Calendars, Calendar Events (create, read, update, delete, attendees, RSVP, recurring events with single-instance changes, custom metadata, and conferencing links), and Free/Busy availability across calendars and providers in one request. Sync tokens and pagination make incremental sync simple. This lets you build anything from scheduling tools to full calendar apps.
• Reasonably priced : Apiroc has a free plan with up to 10 End User Accounts for non-production use. The Pro plan costs $25 per month and includes 50 End User Accounts, then $0.50 per extra End User Account per month. Enterprise pricing is custom, with volume discounts.
• Easy to set up and integrate with : Apiroc is designed to be easy to use and set up. After signing up, you authenticate with an API key in the x-api-key header and can start testing in minutes. There is an official Node.js SDK (@apiroc/unified-calendar-api-node-sdk) and an example application on GitHub.
• Detailed documentation : We have done our best to make the Apiroc documentation as clear as possible. From authentication, pagination, and rate limiting to all supported resources, you will find everything there. We also provide a Postman Collection so you can quickly test the APIs and check if the Calendar API is the right fit for your use case.

Apiroc Pricing

Apiroc has three plans. The Free plan costs $0 per month and includes up to 10 End User Accounts for non-production use, unlimited API requests, 20 requests per second, webhooks, and metadata. The Pro plan costs $25 per month, includes 50 End User Accounts, and then costs $0.50 per End User Account per month. It is meant for production use and comes with 300 requests per second and priority support. The Enterprise plan has custom pricing, volume discounts, custom rate limits, and a dedicated Slack channel.

An End User Account is one connected provider account (for example one Google account), which can contain multiple calendars.

2. Cronofy - For Calendar/Scheduling API

Cronofy is a Nylas alternative that focuses only on Calendar and Scheduling APIs. It uses a flatter pricing model, as opposed to the per-connected-account pricing of Nylas.

Cronofy Features

• Support for iCloud Calendar, Google Calendar, Microsoft Exchange, and Outlook.
• Calendar API : Using Cronofy, you can read from and write to all major calendar providers.
• Scheduling API : Besides the Calendar API, you can use Cronofy to build custom scheduling solutions and embed them in your application.
• Support for webhooks : Cronofy can send push notifications, so your app is notified when calendars change.
• SOC2, GDPR, and other related certifications : Cronofy is SOC2, ISO27001, and ISO27018 compliant.

Cronofy Cons

• High initial pricing : Nylas charges per connected account (starting from $0.90 per connected account per month). The Cronofy Calendar API product, on the other hand, starts from €749 per month. Each pricing model has its pros and cons, but if you are a small startup just getting started, Cronofy has a higher entry price.

Cronofy Pricing

Cronofy has two pricing sections, one for the Scheduler and one for the API.

The Scheduler product starts from €14 per active account per month and goes up to €2,749 per month.

The API pricing starts from €749 per month, with a limit on connected accounts. The second tier starts from €2,199 and has a higher limit on connected accounts. If you exceed the limit, you pay per connected account.

3. Unified.to - For Calendar API, Communications API

Unified.to is a newer unified API product. It offers a Unified Calendar API, a Unified Communication API, and tens of other APIs.

• Expensive to get started : Unified.to offers a Test plan that you can use to try the integrations. The cheapest paid plan starts from $350 per month, which is a higher price point than Nylas. If you exceed 50,000 monthly API calls, you have to move to the Grow plan, which starts from $750 per month.

Unified.to Pricing

Unified.to has a Test plan for non-production applications. Paid plans start from $350 per month, based on your monthly API calls. The Start plan has a limit of 50,000 monthly API calls, which can be used up quite quickly. The next plan is Grow, which starts from $750 per month and allows 750,000 monthly API calls. The top plan costs $3000 per month and allows 6,000,000 monthly API calls.

Note that each plan can cost more depending on your usage.

Unipile Pricing

Like Nylas, Unipile charges per connected account per month. For 11 to 50 connected accounts, you pay $5.50 per account per month. The more accounts you connect, the cheaper it gets.

Compared to Nylas, Unipile is more expensive. Nylas charges $3.30 per connected account per month if you pay monthly, or $1.35 if you pay annually (annual plans have a big discount).
