Software for interior designers and architects in 2026 compared

This comparison was prepared by the Listoria team. The data comes from the vendors' public websites. Listoria's data is current as of 4.11.2026, the other tools' data as of 26.10.2026. Prices and plans change often, so check them with the vendor before you buy.

What to look for when choosing interior design software?

In a small studio the choice comes down to a few practical questions. These six criteria show the differences between the tools fastest.

• Store extension. It saves a product's name, price, photos and link in one click. Check which browsers it works in. You can read how it works in practice in our post about the extension for saving products.
• Cost estimate. It should handle VAT, net and gross amounts and keep an eye on the budget. See how a cost estimate for interior designers works.
• Client portal without an account. The client opens a link and approves products without creating an account or a password. That is how the client panel in Listoria works.
• Entry price and free plan. A free plan lets you work on a real project with no deadline. A trial ends after a few weeks and requires a decision to buy.
• Teamwork. Some tools charge for every person, others have one price for the whole studio. Work out what you will pay for your team.
• Scope beyond the list. Only some tools have contracts, payments, tasks and a site log. If you need them, start with this criterion.

Interior design software compared in a table

Data as of: Listoria 4.11.2026, other tools 26.10.2026. Prices as listed on the vendors' websites. M2 Planner, Interlio and Interioo describe a client portal, but we have no confirmed information on whether the client has to create an account in it. “No data” means we found no confirmation, not that the feature is missing.

The tools one by one

Listoria

Listoria suits a studio that wants to keep shopping lists, the cost estimate and client approvals in one place and start at no cost. The Free plan costs 0 PLN for good and needs no card. It is limited to 1 active project, 4 rooms, 30 favourites and 1 interview. Pro costs 32.99 PLN a month or 296.99 PLN a year, and you can try 7 days of Pro for free. The extension works in Chrome and Firefox, and on Pro AI fills in missing fields. The estimate handles VAT, net and gross amounts, and the budget of the project and of each room. The client approves items in the panel without creating an account. Teamwork is on Pro, at 14.99 PLN a month per person. Listoria has no contracts, payments, tasks or site log.

KIS List

KIS List has been on the market the longest of the tools in this comparison. It suits studios that work with clients in several languages: the interface is in Polish, English, German and Ukrainian. The KISer extension works in Chrome, Firefox and Safari, and it also has an app for iOS and Android. It is the only extension in this comparison that also works on the phone.

M2 Planner

M2 Planner also covers the formal side of working with a client. It has contracts and online payments, which most tools in this comparison do not offer. On top of that it has a list, an estimate, a moodboard, a client portal, an AI survey and an AI schedule. Clients can find a studio in its directory of architects. The Architect plan costs 49.99 PLN a month or 499.99 PLN a year, and the trial lasts 7 days. The extension works only in Chrome, and there is no mobile app. The interface is in Polish, English and Ukrainian. It is a good choice when you want to sign contracts and take payments in the same system where you keep your lists.

Planify

Planify has one price for the whole studio, with no per-person fees. It costs 108.99 PLN a month, or 90.99 PLN a month billed yearly. The cost does not grow when more people join the team. The trial lasts 21 days, the longest in this comparison. The extension works in Chrome and Safari. You can fill the product schedule and the estimate by importing PDF and Excel files. It also has a moodboard, a survey, tasks and proposals that the client approves. The client portal works with a link and a PIN. The interface is in English, Polish and German. There is no free plan.

Interlio

Interlio focuses on organising the studio's work. Besides an estimate with versions, it has a moodboard, a client portal and surveys. You manage tasks on a Kanban board and deadlines in a calendar. The Pro plan costs 49 PLN a month, and Business costs 99 PLN a month and covers a team of up to 10 people. The trial lasts 14 days. The extension works in Chrome and Firefox. There is no mobile app, and the interface is in Polish only. Interlio suits a studio that wants lists and task planning in one place.

Interioo

Interioo is useful for studios that also supervise the build. It has a site log, tasks and forms, plus a list, an estimate, a moodboard, an investor portal and offers for the client. The extension works in Chrome, Edge and Firefox. Prices start at 40 PLN a month net billed yearly, which is 480 PLN a year. The vendor notes that these are introductory promotional prices. The trial lasts 14 days, and there is no free plan. The interface is in Polish and English. You can read more about the differences in our comparison of Listoria and Interioo.

Specora

Specora focuses on specifications and shopping lists. What sets it apart is AI that recognises products in visualisations. It also has a client panel via link and a moodboard. It costs from 39 PLN a month, or 30 PLN a month billed yearly. The trial lasts 7 days. We have no confirmed data on its extension, estimate, teamwork or languages, so the table says no data. Specora suits a studio that starts from finished visualisations and wants to turn them into a product list quickly.

H2Home, Pyklo and Formly Studio also operate on the Polish market. We do not cover them in this comparison.

Which interior design software should you choose?

• You are starting out and want it free: Listoria on the Free plan. It is the only free plan with no time limit in this comparison.
• You need contracts and payments: M2 Planner. It has contracts and online payments in the same system as the list.
• A larger studio with a team: Planify with one price for the whole studio, or Interlio Business for a team of up to 10 people. In Listoria you pay per person: three people on Pro come to 62.97 PLN a month.
• You work in several languages: KIS List with four interface languages. Planify and M2 Planner have three each.
• You want the fastest way to bring products in from stores: KIS List, if you also pick products on your phone. Listoria, if you work in Chrome or Firefox and want AI to fill in missing fields on Pro.

Summary

There is no single best tool for every studio. Start with the criterion you cannot work without: contracts, a site log, a team or a free start. Then test two or three tools on a real project, not on sample data. If you are looking for software for interior designers that you can try with no deadline and no card, Listoria lets you do that on the Free plan.
