piblaster (P&ID software)

About this app

piblaster is browser-based P&ID software for creating piping and instrumentation diagrams and process flow diagrams to ISA-5.1 and DIN EN ISO 10628 — built for process engineering. Draw from a standards-compliant symbol library covering vessels, pumps, valves, heat exchangers and instrumentation. Tag numbers and bill of materials builds itself as you draw. CSV export feeds straight into costing, ERP or procurement. PDF export produces review-ready documents. Projects are versioned, and teams can work on one current revision with roles and permissions. Also included: custom shapes and libraries, pipe and insulation representation, multi-sheet projects, and a guided onboarding tour. No installer, no license server, no IT rollout: piblaster just runs on Windows, macOS, Linux straight in the browser - a genuine alternative to Visio, AutoCad, PlantEngineer, M4 PLANT or Smap3D. Free 30-day trial, no credit card required. Pro plan EUR 29 per user/month plus VAT.

Key features

1Live BOM generation as you draw, with automatic tag numbering and real-time updates.
2Standards-compliant symbol library (ISA-5.1, DIN EN ISO 10628) with vessels, pumps, valves, instruments.
3Browser-based, cross-platform (Windows, macOS, Linux, iPad, Android) with no installation required.

Scout Review

Written by AI from measured evidence, scored out of 100.

piblaster is a promising browser-based P&ID tool that addresses a real pain point: complex, expensive, and hard-to-learn software. Its standout feature is the live BOM that updates as you draw, a genuine differentiator. The design is clean and modern, with a strong homepage demo. Usability is good with a guided tour and free trial, but documentation is lacking. Speed is excellent on desktop but poor on mobile. Security is solid but lacks advanced headers and certifications. Accessibility has minor issues. Growth potential is high given the underserved segments, but competition is entrenched. Overall, a solid early-stage product with clear value, but needs polish in mobile performance and documentation to compete effectively.

Measure by measure

Usability

Guided onboarding, free trial, and intuitive editor layout with live BOM feedback. Docs/help center missing, but core workflow is straightforward.

Design

Clean, modern design with consistent blue accent and strong visual demo of live BOM. Minor dated elements and icon clarity issues.

Speed

Desktop performance excellent (97/100), but mobile LCP 7.5s is poor. Site is lightweight, but app load on mobile needs work.

Security

Strong baseline: HTTPS, HSTS, frame protection, DMARC. Missing CSP and Permissions-Policy. DSGVO-compliant data storage in Germany claimed, but no SOC 2/audit evidence.

Accessibility

Lighthouse 89/100, but failing contrast, heading order, user-scalable=no, and missing main landmark. German-only site, no a11y statement or multi-language support.

Growth

Clear problem, specific segments, and a strong differentiator (live BOM) that generic tools lack. Category has headroom, but competition is entrenched.

Improvement areas

Mobile performance: LCP 7.5s is too slow; needs optimization for tablet/phone users.
Documentation: No help center or detailed guides; users need more than a guided tour.
Security headers: Missing CSP and Permissions-Policy; consider adding SOC 2 for enterprise trust.

Design & Usability

piblaster presents a polished, modern interface with a clear value proposition: draw P&IDs and get a live BOM. The homepage effectively demonstrates this with a side-by-side editor preview. Usability is strong with a guided tour and free trial, but the lack of a dedicated docs/help center is a gap. The editor's single-view layout (palette, canvas, BOM) reduces context switching, a thoughtful touch. However, the symbol palette's small icons and lack of visual grouping could hinder quick identification, especially for new users. Overall, the design is above average for an early-stage tool, but usability would benefit from more comprehensive documentation and clearer iconography.

Speed & Security

Speed is a mixed bag: desktop performance is excellent (97/100 Lighthouse), but mobile suffers with a 7.5s LCP, which is unacceptable for a browser-based tool that claims to work on tablets and phones. The site itself is lightweight, but the app's initial load on mobile needs optimization. Security is solid with HTTPS, HSTS, and DMARC, but missing CSP and Permissions-Policy are notable gaps. The DSGVO compliance claim is positive, but no third-party audits or certifications are visible. For a tool handling engineering data, a SOC 2 or similar would boost confidence. Overall, security is on par with peers, but speed on mobile is a clear weakness.

Accessibility & Growth

Accessibility is decent (Lighthouse 89/100) but has specific issues: contrast ratio, heading order, user-scalable=no, and missing main landmark. The site is German-only, limiting its reach. No a11y statement or multi-language support is a missed opportunity for a tool targeting international engineering teams. Growth potential is strong: the problem (complex, expensive P&ID tools) is real, and the live BOM differentiator is compelling. Target segments (SMEs, academics, plant operators) are underserved. However, competition from established players like AutoCAD and Visio is fierce, and piblaster must prove it can scale beyond its niche. The idea has headroom, but execution and marketing will be key.

Conclusion

If you're a process engineer tired of wrestling with AutoCAD or settling for generic diagramming tools, piblaster is worth a 30-day trial. The live BOM alone could save hours per project. Just don't expect it to replace your entire CAD suite yet—it's a focused tool for P&ID creation, not a full engineering platform. With a few improvements in mobile speed and documentation, it could become a go-to for SMEs and academics. For now, it's a strong contender in a niche that's ripe for disruption.

Suggestions for improvement

Add a comprehensive help center with tutorials, FAQs, and video guides to support the guided tour.
Optimize mobile performance by reducing initial load time, possibly with lazy loading or a lighter editor mode.
Implement CSP and Permissions-Policy headers to strengthen security posture.
Add multi-language support (at least English) and an accessibility statement to broaden reach.
