Get Started

Three minutes to organized

No demo calls. No onboarding. Just sign up and start managing.

Create your workspace

Import or build

Upload your existing spreadsheet via CSV, or start fresh by adding subnets and folders from scratch.

Manage with confidence

Every change logged. Every conflict caught. Your network data is finally a source of truth, not anxiety.

Features

Everything. Nothing extra.

The tools you actually need to manage a network, without the bloat of enterprise IPAM solutions that take months to deploy.

Subnet Tree

Your entire network as an interactive hierarchy. Subnets auto-nest under parent CIDRs. Color-coded utilization shows what's full and what's free at a glance.

IP Tracking

Every address documented. Hostnames, MACs, owners, custom fields. Find the next available IP instantly with one API call.

Split & Merge

Divide subnets with one click. Preview the result before committing. Plan capacity expansions without guessing.

Instant Search

Cmd+K to search everything. Subnets, IPs, hostnames, descriptions. Full-text search with results in milliseconds.

CSV Import

Migrate from spreadsheets in minutes. Upload a CSV, map your columns, and you're live. Export anytime.

REST API

Full read/write API with Bearer token auth. Integrate with scripts, CI/CD pipelines, or build whatever you need.

API-First

Your network as an API

Most IPAM tools treat their API as an afterthought. Ours is a first-class citizen. Every action in the UI is an API call. Automate provisioning, sync with your CMDB, or build internal tools on top of your IP data.
