The ATS Market in Numbers: Live Tracker of Every Applicant Tracking System (2026)

By Ryan Bradshaw · Live tracker, counts refresh from the Work Insiders directory · Last count November 5, 2026

What are the key ATS market numbers in 2026?

The ATS category on Work Insiders holds 204 applicant tracking systems. 52 are built for staffing and search agencies, 125 for in house corporate hiring teams, and 27 are HR suites with an ATS module attached to payroll, HRIS or workforce management.

34 platforms (17%) ship a Model Context Protocol server so an AI agent can work inside them. Read MCP for recruiters for the background. 104 platforms (51%) publish an API. 26 (13%) offer a real free tier, 38 offer a free trial only, and 86 (42%) will not show a price until you book a demo.

Put another way: if you run a small agency, most of the tools built for you publish a price you can act on today, since only 35% of agency ATS hide it. If you are buying a full HR suite, 56% will make you talk to sales first.

And if you want an ATS that plugs straight into Claude, ChatGPT or Grok through MCP, your odds are far better on the agency side of the market (35%) than on the corporate side (10%).

What changed since the September census?

On September 21, 2026 the category held 117 platforms: 35 agency, 63 corporate and 19 HR suites, with 24 MCP servers and a median published price of $85 a month. By October 8 it held 180. The jump came from adding LinkedIn certified ATS partners, healthcare and public sector applicant tracking, and a wave of European and Australian tools, most of them on the corporate side.

That is also why the MCP share fell even as the number of servers grew. Most of the new corporate tools arrived without a server, so the denominator grew faster than the count. This page now runs live, so the next change will show up the day the listings change.

How big is the applicant tracking system market?

The global ATS market is worth about $3.17 billion in 2026 and is projected to reach $4.33 billion by 2030, according to Research and Markets.

Other analyst houses land in a similar range, between $2.65 billion and $3.2 billion for 2026, with growth of roughly 7% to 9% a year. The spread comes from how each firm defines the category. Some count only standalone ATS software. Others fold in the recruiting modules inside HCM suites.

Adoption at the top of the market is close to total. Jobscan’s annual audit detected an ATS on 97.8% of Fortune 500 career sites in 2025. Workday alone powers more than 39% of them and SAP SuccessFactors another 13%.

That concentration at the enterprise end is why the interesting competition happens further down: among agencies, mid market companies and hourly employers, where well over a hundred vendors fight for the same desks.

How many ATS platforms are there?

Nobody has a definitive count, because the line between an ATS, a recruiting CRM and an HR suite keeps moving. Our directory holds 204 as of November 5, 2026, up from 108 at our first count on September 11, 2026.

We include agency desk tools like Bullhorn, Loxo and Vincere that review sites sometimes file under staffing software. We include HR suites like Rippling and Workday only when the ATS module is a real product people buy on its own merits. We stop counting a tool when it no longer has a public website, an active pricing page and a working sign up or demo flow.

What is the difference between an agency ATS and a corporate ATS?

An agency ATS is built for a recruiting firm that places candidates with many clients. A corporate ATS is built for one employer hiring for itself.

The difference shows up in the data model. Agency tools carry client companies, job orders, placements, fees and often a full CRM for business development. Corporate tools carry requisitions, hiring managers, interview kits and offer approvals.

As The Undercover Recruiter puts it in its four way comparison, Greenhouse leads on structured corporate hiring data while Bullhorn is unmatched for agency metrics like fill rate, billable hours and gross margin.

We tag every platform by who it is primarily sold to. The split is an editorial call, so a few tools sit on the fence (Zoho Recruit, Manatal and Carerix all sell to both sides), but the shape is clear: corporate tools are the majority, agency tools are about a quarter, and HR suites are the smallest group.

Inside the corporate group there is a second split worth knowing about. A sizeable block is built for hourly and high volume hiring rather than salaried roles: Fountain, Workstream, Harri, Paradox, Team Engine, Hireology, CareerPlug, StaffedUp and Wizehire among them. These lean on text to apply, chat screening and shift scheduling instead of scorecards and structured interviews. If you hire restaurant, retail, logistics or franchise staff, that sub group is your real shortlist.

Which ATS do staffing agencies actually use?

Reddit threads on r/recruiting and r/RecruitmentAgencies keep coming back to the same handful of names. A roundup of five threads found the discussion splits into two groups: small and new agencies looking for something affordable and simple, and high volume temp shops leaving Bullhorn for something built for their scale.

The names that come up for small desks are Recruit CRM, Loxo, Manatal, Zoho Recruit and Crelate. The names for temp and contract volume are Avionté, JobDiva, CEIPAL and TempWorks. One construction recruiter in those threads admitted to running most of the real work in Excel while nominally paying for a name brand tool. That is more common than any vendor case study will tell you.

Our own desk runs on PCRecruiter as the ATS and CRM, with an MCP connection into Grok so the bot team can search candidate and manager records directly. That is not a recommendation for everyone. It is one working example of an agency stack where the ATS is the system of record and the AI does the searching.

How many ATS platforms have a free tier?

26 of the 204 platforms (13%) offer a free tier you can use indefinitely. Another 38 (19%) offer a free trial that ends after a set period. We count those separately because a trial is not a free plan, and plenty of “free ATS” lists blur the two.

The full live list sits in the tracker above. By segment, 17 of the free tiers are corporate tools, 6 are agency tools and 3 are HR suites. You can also browse them on our free ATS page, or read our guide to free ATS plan limits.

Is a free ATS good enough for a small business?

For one to three open roles at a time, yes. Typical free plans cover job posting, a candidate pipeline, basic email and a careers page.

Where they stop is usually the number of active jobs, the number of users, job board syndication or reporting. The moment you need two recruiters working the same pipeline, or you want postings pushed to Indeed, LinkedIn and ZipRecruiter automatically, you are on a paid plan.

The trap is not the free plan itself but the export. Check that you can pull your candidate data out as a CSV before you load 500 resumes into a tool you might outgrow.

How much does an applicant tracking system cost?

106 of the 204 platforms (52%) publish a starting price on their website. Among the 83 that quote in US dollars by the month or year, the median published entry price is $79 a month.

Published prices are almost always per user or per seat on the agency side and per company or per active job on the corporate side. A five recruiter agency paying the agency median of $95 a seat is spending five times that each month before add ons like texting, job board credits or contact data.

A ten person startup on a flat corporate plan pays the same whether two or ten people log in. That structural difference matters more than the headline number when you compare tools across segments. For the wider picture across every category, see our live recruiting software pricing tracker.

Why do so many ATS vendors hide their pricing?

86 platforms (42%) are quote based: no price anywhere on the site, just a demo form. By segment, 35% of agency tools hide their price, 42% of corporate tools and 56% of HR suites.

HR suites hide prices most because they are selling payroll, benefits and time tracking in the same contract, and the ATS is one line item. Agency buyers are recruiters who compare tools for a living and walk away from a demo form, so agency vendors publish. Corporate buyers are HR generalists who expect a sales cycle, so enterprise vendors negotiate.

How many ATS platforms have an MCP server?

34 of the 204 (17%) ship a first party Model Context Protocol server. MCP is the open standard, originally published by Anthropic, that lets an AI assistant like Claude, ChatGPT or Grok read from and write to a piece of software through a defined set of tools rather than through screen scraping or a custom integration.

For a recruiter, an ATS with an MCP server means you can ask your AI assistant to find every candidate who interviewed for a controller role in the last six months, summarize the notes, and draft a follow up, without leaving the chat. The tracker above lists every ATS with a server by segment, and the wider picture across every category sits in our live MCP tracker.

Are agency or corporate ATS platforms more likely to support MCP?

Agency tools, by a wide margin. 18 of the 52 agency platforms (35%) have an MCP server. Only 13 of the 125 corporate platforms (10%) do, and 3 of the 27 HR suites (11%).

The agency number is driven by a wave of newer desk tools built around AI from the start, alongside established players like PCRecruiter, Loxo, Recruit CRM and Recruiterflow that have added servers. On the corporate side, Greenhouse, Ashby and Workable are the recognizable names with MCP, while Lever, iCIMS and SmartRecruiters expose an API but no MCP server yet.

The reason is structural. Agency recruiters spend their day searching a database of people they already know, which is exactly the task an AI assistant with database access is good at. Corporate recruiters spend more time coordinating hiring managers and interviews, where the AI value is less obvious and the compliance stakes around automated decisions are higher. Expect the corporate number to rise, but slower.

How many ATS platforms have a public API?

104 of the 204 (51%) publish an API. 29 have both an API and an MCP server, 75 have an API only, 5 have an MCP server without a documented public API, and 95 (47%) have neither.

MCP without a public API is a new pattern: the AI connection arrives before the developer one. Some platforms with neither integrate through partner marketplaces rather than open endpoints, so check the integrations list before ruling one out. To see which tools connect to a specific ATS, use our ATS compatibility checker.

Does an ATS need an API if it has MCP?

For most recruiters, no. An API is for developers building an integration: syncing candidates to a job board, pushing placements to payroll, feeding a BI dashboard. An MCP server is for people talking to an AI assistant.

If your team is three recruiters and nobody writes code, MCP gives you more day to day value than an API you will never call. If you run a 40 seat agency with an IT contractor and a Power BI dashboard, you want the API, and MCP is a bonus. The safest bet is a tool with both, and 29 of the 204 now qualify.

What do the numbers say about where the ATS market is heading?

Three things stand out. First, MCP is spreading fastest where AI does the most obvious work, which is candidate search on agency desks. Second, transparent pricing is an agency market feature and a corporate market exception, and that gap is unlikely to close because the buyers are different people with different expectations. Third, free tiers are rare on every side of the market, so most buyers should budget for a paid seat from day one and evaluate on a trial.
