Custom classifieds software, without starting from zero.

Most custom classifieds software projects rebuild the same parts: listings, search, accounts, messages, payments, moderation. Yclas gives you those ready and lets you shape the rest: your own fields, account types, design, code sections, API and webhooks. What the platform cannot do, our team can build, and we will tell you plainly when a build from scratch is the better route.

Honest scope

Yclas is built for small and mid-size classifieds sites and marketplaces. It is a hosted platform, so you shape it through settings, design, code sections and the API; its source code stays with us.

Fits with our helpA custom look, a new field type, a stock feed or a link to a system you already run.

Your data model Every plan

Fields for exactly what your market sells.

Add fields to any category: text, numbers, money, ranges, dates, dropdowns, checkboxes, links, videos and more. Each can be required, shown on the listing, used as a search filter and limited to chosen categories. Ready-made packs set up cars, property and equipment, with specs such as VIN, mileage, bedrooms or machine hours, and you can change any of it afterwards.

User fields too, for sign-up details you need.
Import maps spreadsheet columns to your fields.

Account types and roles that match how you work.

On Professional and up, choose private or business accounts at sign-up, create your own account types with their own rights and approval, and give staff moderator or translator roles, or roles you define. Every setting changed, listing deleted and order refunded is in the audit log.

Verified badges: ID verified and Verified business, on every plan.
Moderation modes: publish now, after approval, after payment.

Your own HTML, CSS and scripts, where you want them.

Custom CSS works on every plan. On Professional and up, custom code sections put your own HTML, CSS and scripts anywhere on a page, such as a calculator, a widget from another service or a layout of your own. If a code section breaks a page, safe mode keeps the admin open so you can fix it.

Header and footer HTML on every plan.

Your systems Basic API on every plan

An API, webhooks and MCP for everything else.

Read and write listings, users, orders, pages and blog posts through the REST API on every plan, documented on your own site. Professional adds webhooks with a delivery log and resend; Marketplace adds keys with their own permissions and an MCP server, so an AI assistant can search listings, change a status or draft a post, with every change in the audit log.

Custom classifieds software: what Yclas covers and what needs a build.

An honest list, including the things Yclas does not do.

Questions

Custom classifieds software FAQ

Part of:

Classifieds software

What is custom classifieds software?

Classifieds software shaped around one market: its own fields, rules, design and connections. It can be built from scratch, or made on a platform like Yclas that is changed through settings, design, code and an API.

Is Yclas enterprise classifieds software?

Yclas is built for small and mid-size sites; the largest plan holds up to 300,000 listings. There is no company single sign-on, no on-premise version and no source code. If you need those, a custom build is the better route.

Can I add my own code?

Yes: custom CSS and header and footer HTML on every plan, and custom code sections with HTML, CSS and scripts on Professional and up.

Can Yclas connect to our CRM or ERP?

Usually, through the REST API or webhooks on Professional. For deeper links, our team builds the integration.

Can you change how a core feature works?

Sometimes. Send us what you need and we will tell you whether it fits the platform and quote it, or explain why it does not.

How much does custom work cost?

It is quoted per project, as a fixed price before work starts. Our brief form has budget bands from under $2,000 to more than $15,000.

Do I keep my data?

Yes. Export everything as one ZIP, and read it at any time through the API.
