Free framing plan software should help you draw structural layout information without implying that it has engineered the result. Evaluate what is genuinely included at no cost, what happens to your data, which exports are available, and whether structural-looking feedback is authoritative or merely illustrative.

The categories of tool, compared
Most tools people try for framing plans fall into one of five groups. The distinctions that actually matter are whether it runs without an install, whether there is a genuine free tier, whether it understands framing rather than generic lines, and whether it can hand off to CAD.
| Category | Runs in a browser | Free tier | Framing-specific | Hands off to CAD |
|---|---|---|---|---|
| General CAD (AutoCAD and similar) | Mostly desktop, some web companions | No | No, it draws lines you interpret | Yes, natively |
| Residential design suites (Chief Architect, SoftPlan) | Desktop | No | Yes, they can generate framing | Yes |
| SketchUp plus framing extensions (such as Medeek) | SketchUp has a free web tier, but framing extensions need the desktop Pro version | Not once extensions are required | Yes, via the extension | Yes |
| Browser room and home planners | Yes | Often | No, they lay out rooms and furniture | Varies, often image only |
| Browser framing tools (including this one) | Yes | Yes | Yes | DXF, on the paid tier here |
Software changes, so treat this as a map of the categories rather than a current feature list, and verify the specifics for any tool before you commit to it.
Why a generic floor-plan app falls short
Floor-plan and interior-design apps are built to lay out spaces. A framing plan is about structure, and that distinction shows up fast:
- Does it model joist direction and on-center spacing, or only draw generic lines?
- Can it display and edit support assumptions without claiming to identify real bearing walls automatically?
- Can it separate joists, beams, grid, and openings for a usable export?
- Does any span feedback disclose its data source, load assumptions, jurisdiction, and limitations?
A general drawing tool may still produce a useful sketch, but a framing-specific data model makes revisions and CAD handoff more consistent.
Do you need AutoCAD for a framing plan?
Not for preliminary layout work. AutoCAD and comparable CAD platforms are excellent at precise drafting, but they do not know what a joist is: you draw lines and give them meaning yourself. For an early-stage framing layout that means repeating the same setup work on every project.
Where CAD does matter is the handoff. If an engineer, drafter, or fabricator needs to continue the drawing, they usually want editable geometry on named layers rather than a flat image. That is what DXF is for, and it is the reason to check export options before you settle on a tool. See framing plan file formats for what each format preserves.
Features a framing-specific tool should have
When you evaluate a free framing tool, check for these:
- Joist span direction and spacing, so you can set which way joists run and their on-center spacing, with the layout updating accordingly. See floor joist spacing explained.
- Editable support assumptions, so the tool can highlight likely end supports for a joist field while making clear that direction does not identify every bearing wall. See load-bearing walls.
- Beams, openings, grid, and columns as real framing elements, not just generic shapes.
- Layered CAD export (DXF), with geometry on named layers so it is usable in CAD. See exporting to DXF.
- Transparent status feedback, with the source and assumptions visible enough to distinguish a demo lookup from a real design check.
- No install, because a browser tool you can open and use immediately is hard to beat for early-stage work.
What you can skip at the preliminary stage
- Full 3D modeling, which is overkill for a preliminary 2D framing layout.
- Heavyweight desktop CAD, powerful but slow to start and unnecessary for sketching intent.
- Code-checking engines that promise compliance, because preliminary tools should inform layout, not pose as engineering. Final sizing and code compliance are the engineer's job.
Where Framing Plan fits
Framing Plan is free to open and draw in the browser: set joist direction and spacing, edit red support assumptions, place beams, openings, a grid, and symbols, and preview the CAD layers. The current free account exports watermarked PNG and PDF, and Pro adds DXF and watermark-free export. The current plan autosaves locally in the browser, so no account is needed to start drawing.
Two limits worth knowing before you start. Its live joist status uses a bundled sample profile whose values are explicitly fabricated for development and demos, not code-derived, so read how Framing Plan generates joists before interpreting the status. And the app authors in millimeters internally, with imperial as a display option, so US users working in feet and inches should expect metric entry fields.
The app is a preliminary layout aid, not an engineering package.
Bottom line
Choose on evidence: structural layout controls, editable assumptions, transparent data sources, usable exports, privacy and autosave behavior, current pricing, and a clear boundary between drawing and design. Open the framing studio to compare those features directly, or start from a framing plan template.
