Why this exists
18 months ago I was combining 4 disciplines in Excel for one customer: solar + battery + heat pump + electrical. Aurora did solar only. Helioscope did solar only. PVsyst was scientific but no drafting. SketchUp plus four plugins half-worked.
So I forked Pascal Editor (MIT, 14 years stable) and built what I needed: one drawing for all 9 disciplines. Local. One-time payment. No cloud lock-in.
What I'm betting on
80% of the solo installers I know do fewer than 30 systems per month. For them Aurora costs $1,872/year = 18-25% of their software budget. Diaz Editor is €99 founding (€500 regular Solo tier once the first 100 are sold). One payment. Lifetime updates.
If the bet is right: 5,000 customers in 24 months. If wrong: I learn what I missed and keep building. Simple.
Tech & process
No mystery. Here's the full stack:
(© Pascal Group Inc.)
(parallel, no SPOF)
(GDPR compliant)
public GitHub release mirror
(roadmap)
Solo dev, no funding, no runway-pitch. Direct from my work laptop to your PC.
Roadmap promise
Public roadmap at diazatlas.com/roadmap. Public changelog at diazatlas.com/changelog. Public GitHub releases at bongartzdiaz/diaz-editor-releases.
If I get hit by a bus tomorrow, €99 founding buyers can fork it — Pascal Editor's MIT license still applies. No ransomware risk. That's a promise with legal backing, not marketing copy.
