Built and Working Today

This isn't a mockup or a roadmap — it's real, running software. Here's what ModularITSM looks like right now.

Modular by Design

Enable only the modules you need — everything beyond incidents is optional.

Roles & Permissions

30+ granular permissions with five built-in roles and custom role support.

Audit Logs

SHA-256 integrity hashing, compliance framework evaluations.

Incident Categories

Sector-specific presets for IT, higher ed, and enterprise.

Assignment Groups

Team-based ticket routing and workload management.

Service Monitoring

Track external service health with alert banners.

Instance Settings

Environment profiles, branding, attachment config.

Announcements

Broadcast messages with publish, draft, and expiration workflows.

Architecture

Composable by Design

ModularITSM isn't a monolith with features bolted on. Every piece is an independent module with a clear contract, so you can adopt incrementally and swap freely.

Independent Modules

Each module — incidents, changes, assets, knowledge — runs on its own and communicates through well-defined interfaces.

Event-Driven Core

Modules communicate through events, not tight coupling. This means extending or replacing any part doesn't break the rest.

Configuration Over Code

Workflows, escalation rules, and approval chains are defined in configuration — not buried in source code you can't touch.

Layered & Extensible

Core services sit beneath optional modules. Build on top of a stable foundation without worrying about upstream breakage.

Fully Isolated Instances

Every deployment gets its own containers, database, and subdomain. No shared infrastructure between customers, ever.

Audit-Ready from Day One

Tamper-evident logging with SHA-256 integrity hashing and built-in compliance framework evaluations — no bolt-on tools required.

Modules

Pick What You Need

Every module is optional. Start with one, grow to many — each one adds capability without adding complexity to what you already run.

Core

Incident Management

Capture, triage, and resolve incidents with configurable severity levels, SLA timers, and automated escalation paths.

Core

Service Request Fulfillment

A self-service catalog for common requests — new accounts, access changes, hardware — with approval workflows built in.

Operations

Change Management

Plan, review, and track changes with risk assessment, CAB workflows, and rollback documentation baked into every change record.

Operations

Asset & Configuration

Maintain a living CMDB that maps dependencies between services, hardware, and software — updated automatically or by discovery.

Planning

Problem Management

Go beyond symptoms. Track root causes, link related incidents, and document known errors so the same issues don't keep recurring.

Planning

Knowledge Base

Capture institutional knowledge in searchable articles. Link solutions to incidents and surface them automatically during triage.

How It Works

From Zero to Running in Three Steps

No week-long onboarding. No consultants required.

1

Clone & Start

Clone the repo and run docker-compose up --build. That's it — the entire stack comes up with a single command.

2

Enable Your Modules

Activate only the modules you need right now. Each one registers itself, creates its own schema, and starts handling events immediately.

3

Configure & Go

Define your workflows, SLAs, and routing rules through the admin interface. No custom code required — but the extension points are there if you want them.

Get Involved

Built in the Open, for Everyone

ModularITSM is a passion project built by an IT professional who believes good service management tools shouldn't require an enterprise budget. It's free, open source, and licensed under AGPL-3.0. Contributions are welcome.
