If you’re evaluating Bentley OpenBuildings for aec (bim architecture) software, the three strongest independent alternatives in our editorial ranking are Autodesk Revit, ArchiCAD, Vectorworks. Each has a different best-fit buyer — the right choice depends on team size and workflow, not on which has the loudest review-site presence.
Why Bentley OpenBuildings sometimes isn’t the right pick: Pure architectural practice (Revit or ArchiCAD better), small design studios (overkill and opaque pricing), or Mac-only design boutiques. See full “worst for” verdict →
9 Bentley OpenBuildings alternatives
| Rank | Product | Best for | Target size | Pricing |
|---|---|---|---|---|
| #1 | Autodesk Revit | Architecture and engineering firms standardising on Autodesk Construction Cloud, US large-firm practice, and any AEC team where Revit fluency is a hiring requirement or contract deliverable. | 5–50,000 | ● Transparent |
| #2 | ArchiCAD | Architectural practices in Europe, Mac-based studios, firms working in openBIM-mandated workflows, and teams standardising on the Nemetschek stack (ArchiCAD plus Solibri plus Bluebeam). | 3–2,000 | ◐ Partial |
| #3 | Vectorworks | Mac-friendly design boutiques, landscape architecture practices, theatre and event designers, and US design-led firms wanting a non-Revit architectural authoring path. | 1–500 | ● Transparent |
| #4 | Allplan | German and DACH structural engineering offices, civil and bridge engineering practices, precast concrete designers, and any AEC team needing reinforcement detailing depth. | 5–2,000 | ◐ Partial |
| #6 | SketchUp | Conceptual and early-design massing, interior designers, landscape architects, residential designers, and any AEC team using SketchUp as a feeder into a primary BIM tool. | 1–5,000 | ● Transparent |
| #7 | Rhino + Grasshopper | Computational and parametric design, facade engineering, geometry-led architecture, academic research, and AEC teams using Rhino as a generative front-end to Revit via Rhino.Inside.Revit. | 1–5,000 | ● Transparent |
| #8 | Revizto | Design coordinators running multi-discipline BIM coordination across Revit, ArchiCAD, Rhino, and IFC models, and AEC teams wanting issue-tracked clash review in one platform. | 10–5,000 | ◐ Partial |
| #9 | Solibri | BIM managers running model QA and compliance checks, owner-operators enforcing ISO 19650 information delivery, and Nemetschek-stack teams wanting integrated model checking. | 5–5,000 | ◐ Partial |
| #10 | FormIt | Autodesk shops needing a Revit-anchored conceptual front-end, AEC Collection users wanting bundled massing, and energy-analysis-led early-design workflows via Insight 360. | 1–10,000 | ● Transparent |
Which alternative for which buyer
Autodesk Revit
Global BIM authoring category leader (NASDAQ:ADSK).
Architecture and engineering firms standardising on Autodesk Construction Cloud, US large-firm practice, and any AEC team where Revit fluency is a hiring requirement or contract deliverable.
Mac-only studios (Vectorworks or ArchiCAD better), small practices priced out by AEC Collection (FormIt or SketchUp better), or teams in openBIM-mandated workflows (ArchiCAD or Allplan stronger on IFC).
ArchiCAD
The BIM-original European alternative to Revit.
Architectural practices in Europe, Mac-based studios, firms working in openBIM-mandated workflows, and teams standardising on the Nemetschek stack (ArchiCAD plus Solibri plus Bluebeam).
US large-firm practices where Revit fluency is a hiring requirement, MEP-heavy firms needing one-tool authoring (Revit better), or teams already deep in Autodesk Construction Cloud workflows.
Vectorworks
Mac-friendly Nemetschek design tool for boutique practice.
Mac-friendly design boutiques, landscape architecture practices, theatre and event designers, and US design-led firms wanting a non-Revit architectural authoring path.
Large architecture practices needing deepest BIM authoring (Revit or ArchiCAD better), MEP or structural engineering firms, or teams in openBIM-mandated infrastructure workflows.
Allplan
German structural and civil BIM standard.
German and DACH structural engineering offices, civil and bridge engineering practices, precast concrete designers, and any AEC team needing reinforcement detailing depth.
US large-firm architectural practice (Revit better), non-DACH practices wanting global recognition, or design-led architectural boutiques (Vectorworks or ArchiCAD better).
SketchUp
Conceptual 3D modelling for early-design massing.
Conceptual and early-design massing, interior designers, landscape architects, residential designers, and any AEC team using SketchUp as a feeder into a primary BIM tool.
Primary BIM authoring at large project scale (Revit/ArchiCAD/Allplan better), MEP and structural engineering, or teams in openBIM-mandated workflows.
Rhino + Grasshopper
Computational and geometry-led design standard.
Computational and parametric design, facade engineering, geometry-led architecture, academic research, and AEC teams using Rhino as a generative front-end to Revit via Rhino.Inside.Revit.
Primary BIM authoring at large project scale, MEP engineering, or teams wanting a single-tool drawing-and-BIM workflow.
