海外TECH DEV Community 11 Best No-Code and Low-Code Back-Ends for 2021 https://dev.to/amanhimself/11-best-no-code-and-low-code-back-ends-for-2021-4i7 Best No Code and Low Code Back Ends for No code and Low code development platforms let people worldwide build their businesses and applications to serve them without writing code According Forrester the no code low code category will grow to billion by Before these platforms building an application for a business would require hiring experienced software developers But that s not the case anymore Today many no code low code platforms make it possible for independent creators artists and entrepreneurs alike to build applications on their own Even though there seems to be a paradigm shift from writing code to using visual development tools the fundamental concepts of having a back end and front end remain the same To build an application for your business you will require a way to connect your back end and front end A communication channel called Application Programming Interface API is used to request information from one computer system to another When developing an application you typically call APIs back and forth between a back end and a front end Draftbit is a visual development platform to build native mobile applications It is back end agnostic Mobile apps built with Draftbit can be connected to virtually any back end as a service BaaS platform via REST API Our vast user base uses different back end services to connect their applications with a database This allowed us to look at the most popular back ends being integrated inside Draftbit For example Xano Supabase Firestore Airtable and more that aim to provide a better user experience overall We are also app development experts and can guide you towards the right back end and what to look for This article aims to highlight some of the best no code low code back end platforms for you to use in We highlight their unique features if the tool offers scalability and if it is flexible enough or not Lastly for each tool there is a sneak peek into their pricing plans Many of the back end tools listed below provide an API gateway to connect the front end from a hosted back end offered by the platform AirtableBest for Beginners who want a visual flexible back end and are just getting started with understanding APIs Airtable is an enhanced version of Google Sheets or a typical spreadsheet However it offers more than that Simple to get started it has rich API support It allows creating a spreadsheet based database without the hassle of writing code In addition it is a fast and flexible way to organize data tables known as Bases It contains features such as computed fields They are special field types where Airtable handles the computation of values Automating repetitive tasks saves a ton of time and reduces the margin of error Building automated workflows in an Airtable base is done by using a custom action to trigger an event Eventually the action integrates inside an Airtable Base Airtable also generates a REST API for each base A front end development tool can consume the API directly Various operations are performed using different endpoints generated by Airtable Operations such as reading writing updating sorting and filtering data and more are all available While Airtable might not be a traditional back end it gives both teams and individuals the freedom to organize tasks In addition it offers built in applications to easily integrate with a wide array of other apps like G Suite Outlook Sendgrid Slack Jira and more Pricing Free unlimited bases with each base limited to records and GB of attachments per base Plus costs per month with records per base snapshot history and GB of attachments per base Pro costs per month with unlimited apps records per base and GB of attachments per base SupabaseBest for Experts who are building production grade applications are familiar with SQL queries value open source and want a scalable solution from the start Supabase is an open source Firebase alternative back end It provides a dedicated database based on Postgres It supports importing existing databases as well Besides there is built in support for making authenticated API requests with integrated JWT authentication This allows you to control what your app users can access It exposes a WebSocket endpoint that enables any front end apps to communicate in real time The advantage of using a relational database is that it helps you be consistent all the time Relational or SQL databases are table based databases They have pre defined schema and use Structured Query Language SQL for defining and manipulating data Non relational or NoSQL databases have dynamic schema They store data in the form of a collection or multiple collections of documents When using Supabase you will spend most of the time inside its Graphical User Interface GUI It also provides an SQL editor which you can use to write custom SQL queries to manipulate data inside a table One of the most likable features is that it provides a ready to use REST API as soon as a database is created It is front end agnostic and can be used with any front end tool building application It gives you the choice of either self hosting a Supabase or using their cloud service to host one Pricing Free per month with unlimited API requests real time functionality and database space up to MB Pro per month unlimited API requests real time functionality database space up to GB supports automatic backup and log retention for up to days Pay as you go Starts at per month plus the usage of services like database space storage and transfer limits Firebase FirestoreBest for Intermediates who are looking to build fast want to delegate security and user management to the backend service and can cope with some learning curve Firebase Firestore is a database service from Google It has a colossal community even though Firestore came out of beta only two years back It is a managed database designed to embrace serverless application development With an Opinionated set of features it provides and is based on NoSQL The NoSQL paradigm lets you store data in the form of collections and documents Each document contains fields Every field has its unique data type The advantage of such a database type is that it helps you move fast when building applications Firestore has its own built in security system It helps you to define rules to allow app users to access data based on their authenticated state It supports traditional sign providers using email password Social providers such as Google Facebook Apple Twitter and more Integrating Firebase with a front end development platform is a bit opinionated It usually means that a no code or a low code platform has to provide an out of the box integration for Firebase to use within their platform Pricing Spark Plan free GiB total stored data in FirestoreBlaze plan pay as you go GiB total plus per more GiB stored data in Firestore XanoBest for Low Coders who want to move fast and need a scalable database with a built in API gateway Xano is a scalable back end that is front end agnostic It provides a hosted and flexible database based on Postgres It supports the REST API paradigm to consume data to a front end tool It automatically generates ready to use REST API endpoints for each data table based on the schema created Each endpoint generated by Xano can be customized using its No code API Builder Getting started with Xano is easy There aren t many configurations required once you log in It abstracts the back end away to a large extent However the abstraction doesn t cost the performance and the power of a database Another feature included with Xano is that it supports authenticated API requests It also provides the ability to create custom functions to query databases without writing a line of code The flexibility and scalability of such a platform make it one of the most simple back end to get started Pricing Free limited to one workspace with total records and a rate limited API Launch costs per month includes
