Dalus
AI-native SysML v2 MBSE platform for regulated hardware teams, with Git-style version control.
Dalus is a strong AI-native MBSE choice for SysML v2 adopters in regulated industries, with a capable AI Copilot and strong compliance. But the free tier is restrictive (1 model, 250 elements), version control is beta, and the ecosystem is younger than legacy tools like Cameo Systems Modeler. Trial it if you need AI acceleration and modern UX; otherwise, wait for maturity.

Skip Dalus if you need mature version control today (it's in beta), if you're a large enterprise with deeply entrenched legacy MBSE models, or if you need a free tier with more than 1 model and 250 elements.
The Basic plan caps at 3 models; if you outgrow that, you're forced to jump to Pro at $249/editor/month.
Dalus is priced for small-to-medium teams willing to invest in AI-assisted MBSE. At $99/editor/month (Basic) it's cheaper than legacy tools like Cameo (often $5k+/year) but more expensive than pure diagramming tools like draw.io (free). Pro at $249 offers unlimited models. If you're a student, the free Pro plan is a great deal.

About Dalus
Dalus is an AI-native Model-Based Systems Engineering (MBSE) platform built for hardware teams in aerospace, defense, automotive, robotics, and energy. It brings requirements management, SysML v2 architecture modeling, analysis and verification, and test case planning into one collaborative environment. The AI Copilot can auto-generate system models from requirements, retrieve information, and flag issues, cutting down on manual modeling work. Recent updates add Git-style version control (Beta) and SysML v2 import/export, making it a real option for teams moving away from legacy MBSE tools like Cameo Systems Modeler. The platform covers the full engineering lifecycle. You get Requirements Management with real-time status tracking, System Architecture with auto-layout, Analysis & Verification via Python scripting, Test Case planning with full traceability, System Safety & Hazards assessment, Mission Planning, Trade Studies, and Part Visuals (upload or AI-generated images and 3D CAD). Excel analysis is built in. Live editing, branching, and role-based permissions handle collaboration. Security is a major differentiator. Dalus is SOC 2 Type 2 certified, runs on AWS GovCloud to help meet ITAR and EAR requirements, offers on-premise hosting, and supports EU data residency for GDPR. That makes it a fit for regulated industries. The free tier is limited to one model with 250 elements, but students with a .edu email can get a free Pro plan. Dalus is positioned as a modern alternative to legacy MBSE platforms, with AI assistance and compliance baked in. Its ecosystem is still younger, and version control is in beta, so it's not yet a drop-in replacement for mature environments. But for teams prioritizing modern UX, AI acceleration, and regulatory compliance, Dalus is worth a serious trial.
Behind the Verdict
Dalus fills a real gap for systems engineers who want a modern, cloud-based MBSE experience without the baggage of legacy tools. The AI Copilot is genuinely useful — it can auto-generate system models from requirements, retrieve relevant info, and spot issues, which accelerates the early modeling phase. The platform’s emphasis on SysML v2 (with import/export now available) aligns with the industry’s forward direction, even though most current models are still in SysML v1. Where Dalus shines is in its compliance posture. SOC 2 Type 2, AWS GovCloud, on-prem options, and EU data residency make it a safe choice for defense and aerospace teams that can't use generic SaaS tools. The Git-style version control (beta) is a welcome addition, but it's not production-ready for all workflows. However, Dalus has limitations. The free tier is a teaser (1 model, 250 elements), the Basic plan caps at 3 models, and on-prem/SSO are Enterprise-only. The ecosystem of integrations is thin (Jira, Slack, GitLab, Simulink) compared to legacy tools. If you're a small team that values AI assistance and modern UX, Dalus is worth a trial. For large enterprises with mature, complex models, you may still need a Cameo or MagicDraw.

Where the pricing makes sense
The company stage and team size where Dalus's pricing actually pencils out — and where peers do it cheaper.
Dalus is priced for small-to-medium teams willing to invest in AI-assisted MBSE. At $99/editor/month (Basic) it's cheaper than legacy tools like Cameo (often $5k+/year) but more expensive than pure diagramming tools like draw.io (free). Pro at $249 offers unlimited models. If you're a student, the free Pro plan is a great deal.
Setup time & first value
How long it actually takes to get something useful out of Dalus — broken out by persona, not the marketing-page minute.
Solo engineers can get a model up in under an hour, thanks to AI onboarding and auto-layout. Teams may need a day to set up roles, permissions, and integrations like Jira or Slack. Importing existing SysML v2 is now possible but may require cleanup.
Switching to or from Dalus
