As a developer, finding the right API for your project can be a game-changer. A well built API can significantly reduce your project timeline, make your life easier, and result in a more robust result. APIs are the foundation of a composable architecture and reason small development teams can build amazing highly complex applications. However, not all APIs are created equal. Some require a significant investment upfront, some are open-source allowing you to test it locally, while others offer free sign-ups or trials to help you test the waters. In this blog post, we will be discussing production APIs for developers and for each category offer the leading SaaS and open-source alternative.
1. Search
Most applications can benefit from a robust search, but search engines are difficult to build and expensive to maintain. It does not make any sense to build your own search when there are great solutions available.
Algolia

It provides a powerful and easy-to-use search solution that includes features such as typo-tolerance, faceting, geolocation, and personalization. Algolia's API can be easily integrated with many different platforms and programming languages, allowing developers to quickly implement advanced search functionality without the need for extensive backend development. With Algolia, businesses can improve their user engagement, conversion rates, and revenue by providing a fast and intuitive search experience for their users.
Elastic Search
Elasticsearch is an incredible open-source search offering. It offers the APIs necessary to power an amazing search experience. Elasticsearch is freely available for download, modification, and redistribution under the Apache 2.0 license.
2. Content Management System
While it's tempting to embed content directly in the code or leverage basic markdown files, once a project is large enough to have business contributors and CMS is needed. These CMS options offer an API-First approach to ensure they are easy to integrate.
Contentful

3. Backend as a Service
Backends as a service (BaaS) allow front-end and mobile developers to build entire applications without the need for server-side coding. They can help in building applications fast allowing teams to launch earlier than trying to build the back-end from scratch.
Firebase
Firebase is an app development platform that helped create this space. Built by Google and hosted on Google Cloud it provides most APIs needed to build an app or SPA.
Supabase
Supabase started as an open-source Firebase alternative, but has grown to include it's own unique set of features and functionality. Built on PostgreSQL it offers a great REST API and SDKs in most programming languages. Offered under the Apache License v2.0 you can download, modify and self-host this BaaS on your own server or cloud environment.
4. Ecommerce
Ecommerce feels like a manageable project until you being diving into the weeds of product bundles, promotions, and payments. Ecommerce represents the classic ninety-ninety rule, where the first 90 percent of the code accounts for the first 90 percent of the development time. The remaining 10 percent of the code accounts for the other 90 percent of the development time. This is why it's best to leverage an ecommerce solution instead of building it yourself.
Commerce Layer
Commerce Layer is API-first and extremely focused. While other companies attempt to handle everything, this company has narrowed the focus to checkout, the core of ecommerce. With a free developer tier and clear published pricing, it's a great option for large businesses.
MedusaJS

The robust documentation will help in creating your first Medusa app, making any desired modifications, and hosting the final solution.
Being purpose built for commerce, Medusa contains many of the endpoints and business logic required for setting up an online store.
5. Authentication
While it's tempting to built your own login system, these are rarely secure. In addition people expect advanced features including social login, 2-factor, passwordless and more.
For this reason it's a good idea to leverage an existing solution.
Auth0
Auth0 makes it extremely easy to integrate authentication into your application. Recently purchased by Okta it is a good choice with many enterprise companies leveraging it's APIs.
SuperTokens
