Config Builder

A local web-based tool for building Cradlepoint .bin configuration files from templates with per-site variable substitution. No cloud or NCM API calls — everything runs on your machine.

Features

• Config Templates — named pairs of Base + Full JSON configs with {{variable_name}} placeholders
• Build — select a template, fill in site-specific values, download Base and Full .bin configs
• Saved Sites — store site data in CSV files for reuse
• Supports .bin file import (auto-decompresses Cradlepoint zlib/gzip exports)
• Variable type validation: string, integer, float, boolean, ipv4, ipv6, cidr, mac
• Light and dark mode

Requirements

• Python 3.7+ (no external packages — uses only the standard library)

Quick Start

cd config_builder
python3 config_builder.py    # macOS/Linux
python config_builder.py     # Windows

Open http://localhost:8100 in your browser.

Workflow

1. Create a Config Template — give it a name, upload/paste a Base config (connectivity on install), then a Full config (applied by remote admin). Replace site-specific values with {{Variable Name}} placeholders.

2. Build — select your template. Fill in the form (RDL, Store Name, Site Address, City, EWP ID, Router Model, plus any template variables). Save the site, then download Base and/or Full configs as .bin files.

3. Reuse — switch to "Load Saved Site" to pick a previously saved site, edit if needed, and re-download.

Variable Syntax

{
  "name": "Vlan2",
  "ip_address": "{{Vlan2 IP Address}}"
}

• {{variable_name}} — defaults to string type
• {{variable_name|type}} — with explicit type (e.g. {{vlan|integer}})

Output Filenames

Downloaded .bin files are named:

RDL{RDL} - {Router Model} - {Base/Full} Config.bin

Example: RDL999222 - E3000 - Full Config.bin
