Instead of AutoCAD
The free AutoCAD alternative depends on one question: 2D or 3D?
AutoCAD is $2,095 a year, and AutoCAD LT still runs about $500. Two free, open-source programs cover what it does — but they cover different halves of it, and choosing the wrong one is the single most common reason people try open-source CAD for an afternoon and give up. There is also one genuine deal-breaker you should read before downloading anything.
Short answer
There is no single answer, and anyone who gives you one hasn't used both. Drawing floor plans and technical drawings in 2D? Use LibreCAD. Modelling parts and assemblies in 3D? Use FreeCAD.
Get LibreCAD — free, from the official site
We don't host this yet, so the button goes straight to the project's own download page. The setup steps below are the part most people get stuck on.
Why every “free AutoCAD alternative” list sends people to the wrong program
AutoCAD is really two products sold as one. Most people use it as a 2D drafting board — plans, elevations, sections, dimensioned technical drawings. A smaller group uses its 3D modelling. The free replacements split along exactly that line, and almost no listicle mentions the split at all.
LibreCAD is a 2D drafting program and nothing else. It is small, it opens instantly, and its command line and layer handling will feel immediately familiar if you have used AutoCAD LT. If you draw plans, this is your answer and you will be productive within an hour.
FreeCAD is a parametric 3D modeller. It is genuinely powerful — closer in spirit to Inventor or Fusion 360 than to AutoCAD — and it is a much larger program with a much steeper start. It can produce 2D drawings, through its Draft and TechDraw workbenches, but using FreeCAD purely as a 2D drafting tool is like buying a workshop to hang a picture.
The usual failure is someone who wants to draw a floor plan installing FreeCAD, because it is the more famous of the two, meeting the workbench system on the first screen, and concluding that free CAD is unusable. It isn't. They installed the wrong program.
Both are alive and maintained: FreeCAD 1.1.3 shipped in July 2026 with commits landing daily, and LibreCAD 2.2.1.5 was updated in August 2026.
What you gain, and what you actually give up
AutoCAD against both free options. The DWG row is the one that decides whether you can switch at all — everything else is preference.

Don't switch if any of these is true
This is the page where the honest answer sends the most people away, so let's be direct. Four situations where free CAD is the wrong choice:
- You exchange DWG files with clients, contractors or consultants. This is the real deal-breaker, and it is not a software-quality problem — DWG is Autodesk's proprietary format. FreeCAD needs a separate converter to read it, LibreCAD's support is basic, and neither round-trips reliably. If a client sends you a DWG and expects a DWG back with layers and blocks intact, keep paying Autodesk. No open-source tool solves this properly.
- You're a student or teacher. Don't use this page. Autodesk gives students and educators a free one-year AutoCAD licence, renewable while you remain eligible. You get the real thing at no cost. It is education-only and cannot be used for paid work, but for coursework it beats every free alternative outright.
- Your firm runs on AutoLISP routines or dynamic blocks. Years of accumulated custom automation does not port. FreeCAD scripts in Python and LibreCAD doesn't script meaningfully at all. Rebuilding that tooling costs more than the subscription.
- You need certification or your industry mandates it. Some tenders, employers and regulators specify AutoCAD files by name. That is a contractual problem, not a technical one, and better software will not fix it.
If you're working on your own drawings, in DXF or starting fresh, none of this applies — and there is no reason to pay $2,095 a year.
Getting started without the usual first-hour frustration
The mistakes that make people quit open-source CAD are nearly always made in the first ten minutes. These five steps avoid all of them.
Pick the right one first
Drawing in 2D — plans, sections, schematics? Install LibreCAD from
librecad.org. Modelling physical objects in 3D? Install FreeCAD fromfreecad.org. If you install the wrong one you will conclude the software is bad when it is simply not the tool for your job. Take both from their official sites — CAD software is a favourite target of download portals that bundle adware.Set your units before you draw a single line
Both programs let you start drawing immediately in whatever default units they came with, and both make it painful to change later. Open preferences and set millimetres, inches or whatever your drawings use before anything else. This is the classic CAD mistake and it is not specific to free tools.
In FreeCAD, understand workbenches before anything else
FreeCAD's single biggest source of confusion: it is not one program but a set of specialised toolsets called workbenches, chosen from a dropdown at the top. Part Design is where you model parts, Sketcher is where you draw the profiles they are built from, and TechDraw is where you turn models into printable drawings. Nothing makes sense until this clicks, and everything makes sense afterwards.
Work in DXF, not DWG
DXF is the open interchange format and both programs handle it natively and reliably. If you control the format, use DXF and the whole compatibility problem disappears. Ask collaborators to send DXF too — AutoCAD exports it perfectly well, and most people will do it if you ask.
Only if you must open DWG — add a converter
For FreeCAD, install the free ODA File Converter and point FreeCAD at it in the import/export preferences; FreeCAD then converts DWG to DXF behind the scenes and imports that. LibreCAD has limited built-in DWG reading. Treat either as “good enough to look at a drawing”, never as a reliable round-trip for work you will hand back to a client.
FreeCAD vs LibreCAD: which one is actually for you?
The comparison people search for constantly, and it has a genuinely simple answer, because these two barely overlap.
LibreCAD is a drafting board. 2D only. It launches in a second, uses very little memory, and its layers, snaps and command line map closely onto AutoCAD LT habits. If your work is plans, elevations, wiring diagrams or anything that ends up printed flat, LibreCAD does that job and nothing else — which is exactly why it is pleasant to use.
FreeCAD is a modelling environment. It builds 3D parts with a full parametric history, so changing a dimension near the start of a design updates everything downstream. That is something AutoCAD itself handles poorly. It is a big program with a real learning curve, and worth it if you are designing objects rather than drawing them.
People also ask about QCAD, which LibreCAD was originally forked from. QCAD's free community edition is capable and its paid Professional version adds DWG support and more tools. If LibreCAD nearly works for you but you need better DWG handling, QCAD Pro is a cheap one-off purchase and a fair middle ground between free and $2,095 a year.
Questions people actually ask
Is FreeCAD really free, even for commercial work?
Yes. FreeCAD is released under the LGPL-2.1 licence with no commercial restriction, no seat limit, no watermark on exports and no feature held back behind a paid tier. You can use it to run a business and owe nobody anything.
The same is true of LibreCAD under GPL-2.0. Neither has a “professional edition”, because there is nothing to upsell you to.
Can I open AutoCAD DWG files?
Sometimes, and never dependably. This is the honest limitation of the whole category.
DWG is Autodesk's proprietary format, deliberately undocumented. FreeCAD handles it by shelling out to an external converter — the free ODA File Converter, LibreDWG or QCAD Pro — which turns the DWG into DXF first. LibreCAD has basic built-in support via the libdxfrw library.
Simple drawings usually come through. Complex ones lose blocks, styling or layer structure. If DWG round-tripping is central to your work, this is the point at which you should stop reading and keep your subscription.
Is there a way to get real AutoCAD for free?
Yes, if you are a student or an educator, and you should take it.
Autodesk provides a free one-year educational licence for AutoCAD, renewable as long as you remain eligible, through their education programme. It is the full product, not a trial.
The restriction is that it is strictly for learning and coursework — you cannot use it for paid or commercial work. For anyone at an accredited school or university, this beats every alternative on this page, and we would rather tell you that than send you to worse software.
Is FreeCAD good enough for professional work?
For design and manufacturing work, increasingly yes. Version 1.0 in late 2024 fixed the long-standing “topological naming problem” that had made complex models fragile for years, and 1.1.3 arrived in July 2026 with development moving quickly.
Where it is still weaker is very large assemblies, polished 2D drawing output, and interoperability with firms standardised on Autodesk. Judge it on your own work rather than on its price.
LibreCAD or QCAD — what's the difference?
LibreCAD began as a fork of QCAD's community edition, so they feel similar and share ancestry.
LibreCAD is entirely free and open source. QCAD offers a free community edition plus a paid Professional version that adds DWG support, more tools and better printing. If LibreCAD covers your needs, use it. If the missing piece is specifically DWG, QCAD Pro is a modest one-time cost rather than a subscription.
Will these run on an older laptop?
LibreCAD, easily. It is a small 2D program and runs comfortably on hardware that struggles with a modern browser.
FreeCAD is heavier. It wants a reasonable amount of RAM and benefits from a graphics card once models get complex, though simple parts are fine on integrated graphics. If your machine is old and your work is 2D, this is another reason LibreCAD is the better starting point.
