Prisma helps app developers build faster and
make fewer errors with an open source ORM for PostgreSQL, MySQL and SQLite. It makes database access easy with an auto-generated and type-safe query builder that's tailored to your database schema. It provides an alternative to traditional ORMs and SQL query builders. 
 
Prisma is the perfect companion for building web APIs. It saves repetitive CRUD boilerplate and provides a flexible API for common use cases such as pagination and filtering. Based on the Prisma Schema, Prisma Migrate automatically generates SQL database migrations, that are fully customizable.

FastAPI is a modern, fast (high-performance), web framework for building APIs with Python 3.6+ based on standard Python type hints. It uses OpenAPI for API creation, including declarations of path operations, parameters, body requests, security, etc. It produces interactive API documentation and exploration web user interfaces.

PostgREST serves a fully RESTful API from any existing PostgreSQL database. The structural constraints and permissions in the database determine the API endpoints and operations. It is an alternative to manual CRUD programming. Custom API servers suffer problems. Writing business logic often duplicates, ignores or hobbles database structure. Object-relational mapping is a leaky abstraction leading to slow imperative code. The PostgREST philosophy establishes a single declarative source of truth: the data itself.

Eclipse Hono provides uniform (remote) service interfaces for connecting large numbers of IoT devices to a (cloud) back end. It specifically supports scalable and secure data ingestion (telemetry data) as well as command & control type message exchange patterns and provides interfaces for provisioning & managing device identity and access control rules.
 
It can connect millions of devices, Its micro service based architecture and use of a reactive programming model allow for scaling out horizontally. It provides APIs for important IoT communication patterns: Telemetry and Event messages can be used by devices to report sensor readings whereas applications can use Command & Control to invoke operations on devices.

RESTX is the lightweight, modular, feature rich, blazing fast, open source Java REST framework. It shares similarities with modern frameworks like Play! like hot compile and a very productive experience, but focused on REST and pure Java.
 
It is focused more on Rest. This implies that it’s not a general web framework, i.e., there is no templating mechanism. It’s better use with a JavaScript framework on the client side, and you can always use any other templating mechanism to serve your pages.

Javalin is a very lightweight web framework for Kotlin and Java, inspired by Sparkjava and koa.js. Javalin is written in Kotlin with a few functional interfaces written in Java. This was necessary to provide an enjoyable and near identical experience for both Kotlin and Java developers.
<ul>
 <li>Lightweight - You don’t have to learn any advanced concepts to get started</li>
 <li>Consistent API - All handlers and mappers are void and operate on the Context (ctx)</li>
 <li>Almost identical API for both Kotlin and Java</li>
 <li>Not opinionated - A library rather than a framework (you never have to extend anything)</li>
 <li>Fully customizable embedded server (Jetty)</li>
 <li>JSON-object-mapping (via Jackson)</li>
 <li>Simple per-endpoint auth via <code class="highlighter-rouge">AccessManager</code> interface</li>
 <li>Simple static file handling</li>
 <li>Lifecycle events</li>
 <li>CookieStore - An easy way to serialize and store objects in cookies</li>
 <li>Template rendering (Velocity, Freemarker, Thymeleaf, Mustache)</li>
 <li>Markdown rendering</li>
</ul>
