DevCenter

Local-first Python IDE and developer toolkit for Windows. DevCenter combines a PySide6 code editor, static analyzer, PyInstaller build helper, license collector, file index and optional Claude/Anthropic assistant in one desktop suite.

Not Azure DevCenter, Microsoft Dev Box, Moderne DevCenter or Devbox. This is dev-bricks/DevCenter — an open-source Python desktop app.

Static code analysis	Analyze tab
Workspace export for PWA companion	File → Export workspace
Windows launcher	START_DevCenter.bat

Product Family & Edition Comparison

DevCenter consists of a highly capable local Desktop Application and a lightweight, offline-ready Web Companion. Their features are compared below:

Feature	Desktop Application (Authoritative IDE)	Web Companion (Static PWA)
Primary Purpose	Full offline local-first Python development, analysis, and build suite	Read-only dashboard for reviewing projects, task lists, and build status
Data Flow	Authors and builds everything locally; generates redacted workspace exports	Imports redacted devcenter-workspace-v1.json completely client-side
Code Editor	PySide6-based editor with syntax highlighting and auto-indent	None (Read-only status overview)
Static Code Analysis	Local AST analysis, complexity checks, and encoding repair	View analysis summaries and detected issue statistics
Build & Release	PyInstaller wrapper, PNG to ICO converter, license collector	View configuration metadata and target platform checklist
Task Management	Directly parses and updates your local AUFGABEN.txt	Visually groups open tasks by priority
Privacy Boundary	Authoritative data store; strictly local unless optional cloud APIs are used	Offline-first PWA, no cloud uploads, completely secure client-side sandbox

Why DevCenter

• Local-first workflow: projects, indexes, settings and build artifacts stay on your machine by default.
• Python desktop focus: PySide6 interface, syntax highlighting, project explorer, terminal output and settings persistence.
• Static analysis built in: method/class detection, complexity checks, import analysis, TODO/FIXME detection and encoding repair helpers.
• Build and release helpers: PyInstaller wrapper, icon conversion, third-party license collection, release notes and export planning.
• Optional AI assistant: Claude/Anthropic integration is opt-in and uses local settings, keyring or environment variables.
• Redacted workspace export: writes a redacted devcenter-workspace-v1.json (see EXPORTFORMAT.md).

Quick Start

git clone https://github.com/dev-bricks/DevCenter.git
cd DevCenter
pip install -r requirements.txt
python main.py

Windows helpers:

START_DevCenter.bat
build_exe.bat

Features

Editor

• Python syntax highlighting, line numbers, auto-indent, multi-tab
• Comment toggle (Ctrl+/), drag-and-drop files

Static Analysis

• AST-based method and class detection
• Cyclomatic complexity, unused import detection
• TODO/FIXME finder, encoding checker and repair

Build System

• One-click EXE via PyInstaller (one-file / one-directory)
• ICO converter (PNG/JPG to ICO)
• Third-party license collector for distributions

AI Assistant

• Claude/Anthropic API integration — opt-in, key stays local
• Code generation, review, explanation, and development loop

File Management

• SQLite file index with full-text search
• Duplicate detection (hash-based)
• Backup sync with automatic WAL checkpoint

Settings and Persistence

• Structured JSON settings for editor, build, AI, sync and appearance
• Import/export support for reproducible setups
• Theme and window state restored on restart

Installation

Requirements: Python 3.10+, Windows 10/11 (primary), Linux/macOS (experimental)

git clone https://github.com/dev-bricks/DevCenter.git
cd DevCenter
pip install -r requirements.txt
python main.py

Dependencies (see requirements.txt):

Tests

python -m unittest discover -s tests -v
python -m compileall -q main.py manage_translations.py translator.py src tests

GitHub Actions runs the same smoke checks on Python 3.10, 3.11 and 3.12.

Privacy

DevCenter is a local desktop application. Projects, settings, file indexes and build artifacts stay on your machine by default. Network access occurs only for explicitly configured integrations such as the optional Claude/Anthropic API or package installation commands started by the user.

API keys must not be committed to the repository. Use environment variables, the local keyring or the app settings.
