Coohom
SMBCloud-based interior and home design platform with 3D rendering and a furniture library.
Template-driven room and furnishing layouts paired with render-focused output for rapid design reviews.
Coohom’s core workflow is a cloud-based 3D editor that lets teams assemble rooms and exterior scenes using library assets, then produce presentation renders. Elevation and section outputs exist for communication, but the tool’s model authoring is centered on visual scene composition instead of BIM-grade parametric modeling. The library-driven approach supports fast layout exploration, especially when standard furniture, finishes, and architectural elements are sufficient.
A key tradeoff is that model intent stays tied to the scene composition workflow, which can make detailed coordination exports less reliable for downstream engineering uses. Coohom fits best when teams need quick review-ready visuals for clients or internal stakeholders, rather than strict document sets driven by a construction documentation model.
- +Browser modeling workflow speeds up client-ready visualization iterations
- +Large built-in asset library reduces time spent sourcing materials
- +Scene templates standardize room layouts across repeated projects
- +Lighting and render controls support consistent presentation output
- –Engineering-grade coordination exports are not the primary workflow
- –Advanced modeling constraints are limited for nonstandard geometry
- –Collaboration features favor review cycles more than structured governance
- –Complex custom objects can be slower than library-based assemblies

Maket
SMBAI-driven generative floor plan tool for residential layout design.
Browser-native drafting with immediate drawing-view packaging for collaborative review cycles.
Maket fits teams that need repeated edits across plans, elevations, and sections without switching to a heavyweight desktop authoring process. The workflow is shaped around quick drafting and view-based outputs that can be packaged for review cycles and internal signoff. Collaboration stays inside the same document so multiple stakeholders can comment on a shared design artifact.
A key tradeoff appears in the documentation depth needed for full BIM authoring workflows, because Maket’s emphasis stays closer to design drafting than to parametric family management. Maket works best when early-stage concepts and iterative drawings must move quickly into review-ready exports. It is a weaker choice when project teams require advanced modeling interoperability like full IFC round-tripping fidelity or constraint-heavy parametric edits at scale.
- +Browser editing reduces context switching during design iterations
- +View-based drawing exports support fast client review cycles
- +Cloud collaboration keeps multiple reviewers on one document
- +Quick creation of plan and elevation deliverables
- –Limited coverage for parametric family workflows at project scale
- –IFC round-tripping depth may lag behind BIM authoring tools

Spline
SMBBrowser-based 3D design tool for modeling, texturing, and interactive scenes.
Web-native interactive scene authoring with adjustable cameras and lighting tied to the same shared 3D context.
Spline’s editor builds scenes from 3D objects, then applies materials, lighting, and camera setups to produce interactive viewpoints for reviews. It supports import and export of common 3D formats and can embed scenes for stakeholder viewing without requiring viewers to install modeling software. The workflow is strongest for conceptual massing, design options, and visualization beats where rapid iteration matters more than document-grade drawing output.
Spline trades away construction documentation depth, since it does not replace 2D drafting workflows for plans, sections, and elevations. A typical fit is an architecture studio that needs fast, shareable 3D presentations for early client feedback, while keeping detailed documentation in a separate CAD or BIM tool.
- +Real-time rendering preview for design option reviews
- +Scene graph workflow with camera and lighting controls
- +Browser sharing for stakeholders without modeling software
- +Good asset reuse for repeated interior and massing variants
- –Limited support for document-grade 2D drawings

Giraffe’s main differentiator is that it treats model changes as first-class events across drawing sheets, so updates can propagate without manual relabeling. Collaboration is handled through project sharing and versioned work states rather than exports-only handoffs.
- +Browser-first authoring reduces friction compared with desktop-only workflows
- +Coordinated view updates cut rework across plans, sections, and elevations
- +Project sharing supports real collaboration without export-driven cycles
- +Sheet-based output streamlines drawing sets from the same model
- –Limited interoperability depth for DWG and IFC workflows versus specialist tools
- –Automation tooling for bulk edits is thinner than code-driven BIM systems
- –Advanced parametric controls can feel constrained for complex family authoring
- –Governance controls like granular RBAC are not as detailed as enterprise CAD
Best for: Fits when small architecture teams need coordinated 2D views and sheet output in one browser workflow.
Rayon
SMBCollaborative browser-based spatial design tool for floor plans and space planning.
Constraint-based template editing that keeps layout geometry consistent while generating documentation exports from the same design state.
Rayon is a browser-based architecture design tool focused on generating and editing building layouts from configurable templates and constraints. The core workflow centers on placing architectural elements, then iterating massing and view outputs through a repeatable design process.

How to Choose the Right online architecture design software
This buyer's guide covers browser-based architecture design tools that produce 2D drawings, 3D visualization, interactive scenes, and early-stage site or massing outputs. The guide names Coohom, Maket, Spline, Giraffe, Rayon, AutoCAD Web App, Arcol, RoomSketcher, Floorplanner, and TestFit and maps them to concrete workflows.
It focuses on integration depth, automation and API surface, and governance-style controls only when those capabilities exist in the reviewed tool set. It also highlights where outputs stay visualization-first, where view-linked drafting matters, and where BIM interchange and documentation depth are limited.
Evaluation criteria for matching browser architecture tools to real design outputs
Architecture teams usually judge online tools by how reliably edits stay connected across views, how quickly drafts become reviewable deliverables, and whether exports fit downstream CAD or BIM pipelines. The most visible differences across Coohom, Maket, Giraffe, Rayon, Arcol, and TestFit come from how model changes propagate and what the tool can generate from that same state.
Automation and integration matter most when external pipelines or governance are required. Arcol is the clearest API-forward example, while several other tools keep integrations shallow and prioritize browser collaboration and export workflows.
View-linked model edits that propagate across plans, sections, and elevations
Giraffe treats model changes as first-class events across connected drawing views and sheet output, which reduces rework when a design shifts. Arcol similarly keeps geometry consistent across plan and elevation views using a constraint-aware sketching workflow.
Constraint-based editing that keeps geometry consistent during iteration
Rayon uses constraint-based template editing so layout geometry stays consistent while documentation exports are generated from the same design state. Arcol’s constraint-aware sketching also reduces manual alignment errors during view-coherent drafting.
Template-driven room and furnishing layout generation for review-ready presentations
Coohom uses template-driven room and furnishing layouts paired with render-focused output for rapid design reviews, which makes it effective for recurring space types. RoomSketcher also keeps furnishing and material choices synchronized with real-time 2D-to-3D updates during layout edits.
Interactive 3D scene authoring with real-time rendering controls in the browser
Spline provides a web-native interactive scene graph workflow with adjustable cameras and lighting tied to the shared 3D context. This approach favors client walkthrough-ready options instead of document-grade 2D drawing output.
2D drafting workflows that package drawings for collaborative review cycles
Maket emphasizes browser editing that turns into publishable drawing view sets for client-facing reviews. AutoCAD Web App similarly targets browser-based DWG edits and annotation workflows that preserve established AutoCAD-style production habits.
Rule-driven massing and site planning that automates placement logic
TestFit uses rule-based layout constraints that automatically reposition modules while preserving program and site logic, which reduces repetitive manual placement during feasibility. This rule-driven approach keeps plans, sections, and elevations consistent after configuration changes.
Decision framework for selecting an online architecture design tool by output shape and integration needs
Start by identifying the deliverables that matter during the next design stage, such as view-linked 2D sheets, PDF documentation, interactive walkthroughs, or rule-driven feasibility outputs. Then pick a tool whose core workflow generates those artifacts from the same editing state.
Next, evaluate integration and governance expectations based on the tool’s automation surface. Arcol is the clearest choice when API-driven automation and provisioning workflows matter, while tools like AutoCAD Web App and Rayon center on document exchange and exports rather than deep external automation.
Choose the tool type that matches the artifact pipeline
For client-ready interactive options, Spline is designed for browser-native interactive scenes with real-time rendering preview. For browser drafting that immediately becomes reviewable view packages, Maket is built around fast plan and elevation deliverables that stay browser-native.
Lock in whether edits must stay consistent across multiple drawing views
If a team needs model changes to propagate across connected drawing views and sheet output, Giraffe is structured around that live propagation mechanism. If geometry consistency across plan and elevation is the priority, Arcol’s view-linked layout workflow and constraint-aware sketching keep edits connected.
Pick constraint and template workflows for the design scale in scope
For template-based space planning that outputs PDF drawings and supports IFC export for downstream exchange, Rayon focuses on constraint-based template editing. For room planning with synchronized furnishing and material assignments during layout edits, RoomSketcher uses real-time 2D-to-3D updates tied to the same layout.
Decide if BIM-grade coordination and parametric depth are required now
If the workflow requires BIM authoring depth and engineering-grade coordination exports, the reviewed browser-first tools prioritize visualization or drafting instead of BIM authoring, so AutoCAD Web App is the closer DWG-centric option for 2D CAD production. If early-stage concept iteration is the priority instead, TestFit’s rule-driven massing keeps plan, section, and elevation outputs consistent without desktop CAD setup.
Match automation and integration expectations to the tool’s API surface
When provisioning and automation need an API surface for workflow handoffs, Arcol is built to support automation and project workflow integration. When the primary integration is export-based handoff, Rayon’s IFC export supports downstream BIM exchange and AutoCAD Web App focuses on DWG editing and common drawing-format export.
Who benefits from online architecture design tools by primary workflow
Online architecture tools fit teams that iterate frequently and need browser access for collaboration and review. They are also suited to workflows that convert a design state into view packages, PDF outputs, or interactive scenes without requiring desktop-only roundtrips.
The best fit depends on whether the next deliverable is a coordinated 2D sheet set, an interactive 3D walkthrough, or rule-driven feasibility outputs. It also depends on whether API-based automation is required or export handoffs are sufficient.
Small architecture teams needing coordinated 2D views and sheet output in one browser workspace
Giraffe supports live project-wide propagation of model edits across connected drawing views and sheets, which directly reduces rework during documentation preparation. It fits teams that need browser-first authoring and coordinated view updates without exports-only handoffs.
Early-stage teams that need fast browser drafting and client-ready drawing-view packaging
Maket turns browser edits into publishable drawing sets for fast review cycles, and it packages plan and elevation views for collaboration. It fits residential layout concept work where speed and iteration matter more than deep parametric family workflows.
Architecture teams that need interactive walkthrough-ready 3D scenes for stakeholder reviews
Spline focuses on web-native interactive scene authoring with adjustable cameras and lighting tied to the same shared 3D context. It fits cases where interactive presentation is the deliverable rather than document-grade 2D drawings.
Teams doing template-based space planning that must export for downstream BIM or drafting
Rayon pairs constraint-based template editing with IFC export so the same design state can feed downstream BIM exchange. It fits teams that need repeatable layouts plus documentation exports without desktop BIM complexity.
Small teams iterating rule-based site planning and massing feasibility in-browser
TestFit is built for browser-based conceptual massing and site planning using rule-driven layouts that automatically reposition modules. It fits feasibility work where consistent plan, section, and elevation updates matter more than construction documentation depth.
Common failure modes when choosing browser architecture tools for real projects
Many selection failures happen when a tool is matched to the wrong output stage. Several reviewed tools excel at fast visualization and review cycles but stay thin on document-grade interoperability, advanced parametric family authoring, or structured governance controls.
Other failures happen when teams assume exports are plug-and-play for engineering workflows. DWG and IFC exchange coverage varies across the set, and some tools require cleanup after importing complex models.
Expecting visualization-first tools to deliver engineering-grade coordination outputs
Coohom is optimized for render-focused presentation output and reusable templates, not engineering-grade coordination exports, so it is better for design review than coordination deliverables. Spline also emphasizes interactive scenes and real-time rendering rather than document-grade 2D drawing production.
Picking a draft-first tool when the project requires strong parametric family workflows
Maket provides browser-native drafting and view packages for early iteration, but it offers limited coverage for parametric family workflows at project scale. Rayon also supports constraint-based layouts and IFC export, but it does not replace BIM authoring for advanced parametric family needs.
Assuming IFC or DWG round-tripping depth will match BIM authoring workflows
Rayon supports IFC export for downstream exchange, but its API and automation surface is minimal, which can block pipeline automation even if exports work. Maket’s IFC round-tripping depth can lag behind BIM authoring tools, which can introduce model cleanup work when data fidelity is critical.
Underestimating how governance and automation scale beyond small team workflows
Floorplanner’s governance and audit logging fit small teams better, so it can under-deliver when formal governance needs expand. Giraffe’s governance controls such as granular RBAC are not as detailed as enterprise CAD, so larger governance expectations require an alternative governance model.
How We Selected and Ranked These Tools
We evaluated Coohom, Maket, Spline, Giraffe, Rayon, AutoCAD Web App, Arcol, RoomSketcher, Floorplanner, and TestFit using three criteria that map to real buying decisions: features, ease of use, and value. Features carried the most weight at 40 percent because online architecture design software selection usually hinges on whether the tool can generate the right 2D or 3D artifacts from the same editing state. Ease of use and value each carried 30 percent because browser-based workflows must stay efficient for frequent iterations and collaboration cycles. The ranking reflects editorial research and criteria-based scoring from the provided tool descriptions, feature lists, and stated pros and cons rather than private benchmark experiments.
Coohom separated itself by combining browser-based modeling workflow speed with template-driven room and furnishing layouts that directly support rapid design reviews. That strength aligned most strongly with the features criterion because its render-focused output and scene template approach reduce time spent rebuilding recurring layouts, which lifted it above other tools in the same browser-first visualization and planning set.
