Essential Productivity Tools Every Backend Engineer Should Use

Backend programmers not only write code but also need to produce design documents and diagrams, so mastering productivity tools is essential for achieving more with less effort.

1. Diagramming

draw.io

draw.io is an all‑in‑one diagram tool that works offline, preserving privacy. It can create architecture diagrams, flowcharts, database ER diagrams, and UI mockups. The desktop version can be downloaded from GitHub, and the online editor is available at app.diagrams.net .

Examples of diagram types:

Architecture diagrams

Flowcharts

Database ER diagrams

UI prototype diagrams

Creating diagram type selection:

Architecture diagram example:

UI prototype example:

uTools

uTools is a toolbox manager that can install many useful small utilities. For backend developers it offers JSON formatting, text diff, timestamp conversion, OCR for screenshots, and a cloud‑based quick note for code snippets.

Activate the search box with Alt+Space and type keywords such as "json", "diff", "timestamp", "ocr", or "note" to launch the corresponding tool.

JSON formatting example:

Timestamp conversion example:

PlantUML

PlantUML lets you generate UML sequence diagrams (and other UML types) from simple text scripts, freeing backend developers from manual drawing.

Example code:

@startuml
autonumber
participant Participant as Foo
actor       Actor       as Foo1
boundary    Boundary    as Foo2
control     Control     as Foo3
entity      Entity      as Foo4
database    Database    as Foo5
collections Collections as Foo6
queue       Queue       as Foo7
Foo -> Foo1 : To actor 
Foo --> Foo2 : To boundary
Foo -> Foo3 : To control
Foo -> Foo4 : To entity
Foo -> Foo5 : To database
Foo -> Foo6 : To collections
Foo -> Foo7: To queue

You can generate the diagram via command line or online tools:

IntelliJ IDEA

IntelliJ IDEA is the premier Java IDE; for Python developers, PyCharm (also from JetBrains) is a strong choice. Download from the official site.

Key features to master:

Automatic class diagram generation (Diagrams → Show Diagram…)

Find Usages to locate dependencies

Breakpoint debugging

Class diagram example (see the author’s "Spring cache source analysis"):

XMind

XMind is used for mind maps to capture ideas and organize thoughts.

2. Document Editing

mdnice

mdnice is a WeChat public‑account markdown formatting tool that can publish articles to multiple platforms with one click, saving time for technical bloggers.

Typora

Typora provides a clean local markdown editing and preview experience.

GitBook / Mindoc

GitBook turns a collection of markdown files into an organized electronic book, useful for building a structured documentation site. Mindoc is a Chinese open‑source alternative with similar functionality.

GitBook example:

3. Terminal Clients

MobaXterm

MobaXterm is a feature‑rich Windows terminal client offering SSH, VNC, SFTP and more, providing a polished alternative to PuTTY or SecureCRT.

JuiceSSH

JuiceSSH is a convenient SSH client for Android, allowing you to run commands and manage servers directly from your phone.
