What Construction Software Has the Most Integrations?

The construction software with the most integrations is Procore, with 539 listings across 439 ISV partners on the Procore App Marketplace. Autodesk Construction Cloud (now consolidated under Autodesk Forma) publishes "over 400 integrations" across its partner ecosystem, and no other construction-native platform comes close to Procore's 539-listing depth. 500+ integrations across 439 ISV partners makes Procore's marketplace the deepest construction-tech ecosystem in the market.

A general contractor running a typical mid-market stack already operates an ERP (Sage, Viewpoint, CMiC), an accounting system (QuickBooks or NetSuite), a BIM and design tool (Revit, Navisworks), a payroll or HCM system, and field-data capture. Picking a platform that does not integrate cleanly with even one of those pieces means manual double-entry, reconciliation cycles, and a hidden tax on every project. Integration debt compounds: every quarter a critical workflow stays unconnected is another quarter of finance teams keying numbers twice, field teams losing data in transit, and PMs working from stale cost positions. Switching platforms later is expensive and slow, which means choosing wrong now becomes a two-year migration when the integration gap becomes unworkable. Here is why Procore's marketplace leads the field, and where Autodesk, Oracle, and Trimble sit relative to it.

Why Procore Wins on Integration Breadth

Procore treats integration as infrastructure, not a feature checklist. The marketplace is wide, the partner program is old, the API is open, and the customer base is large enough to make every ISV's investment pencil out. Each of the next five sub-sections takes one of those pieces and works through the evidence.

The Raw Numbers: 539 Listings, 439 ISV Partners

The Procore App Marketplace currently lists 539 distinct integrations and now features 439 independent software vendors. The ISV count matters more than the listing count: 439 vendors mean 439 separate engineering teams have invested in building, certifying, and maintaining a Procore connector. That is not a directory of rebranded internal connectors. That is real partner-side investment.

Scale is the precondition for the partner economics. Procore now serves over 1.4 million users worldwide and projects in more than 125 countries, which is the install base that makes integration economically rational for an ISV to build. The marketplace exists at this depth because the customer base is large enough to support it.

Geographic spread of partners runs 68.51% United States, 7.58% Australia, and 6.41% Canada, with the remaining ISVs distributed across the UK, EMEA, and the rest of APAC. For a GC operating across North America with selective international project exposure, the marketplace surface is wide enough that the integration is unlikely to be the blocker.

Coverage Across Every Category a GC Actually Needs

Total listing count is the headline; category coverage is the workable insight. The marketplace is deep across every operational sub-category a GC actually runs.

On the ERP side, Sage, Viewpoint Vista, CMiC, and Acumatica all have published connectors that move job-cost data and commitments between the field and the back office. On the accounting side, QuickBooks and NetSuite plug directly into Procore Financials. On the BIM and design side, Autodesk Revit and Navisworks feed into Procore for clash detection and submittals; Bluebeam connects for document markup and RFIs. On the HCM and payroll side, Criterion HCM integrates with Procore so timesheets and employee data sync without re-keying. Drone capture, reality capture, safety, lien waivers, COI compliance, and document signing each have multiple competing apps listed.

The depth lets a GC pick the best-of-breed app in each operational lane and trust that Procore will be the hub. A GC running Sage on the back end, Revit in preconstruction, and a field-data capture app on the iPads can wire the whole thing through Procore without a custom middleware layer. 95%+ of Procore customers use at least one integration, which is the strongest signal that the marketplace is not a vanity directory.

A Ten-Year Head Start on the Ecosystem

Procore launched the App Marketplace and Partner Program in 2016, and the platform has been actively recruiting and certifying integration partners for nearly a decade. The launch announcement put the original partner count at roughly 20 ISVs. The current count is 439. That growth, from 20 partners to 439 in under a decade, is the kind of compounding that a single quarter of competitor investment cannot close.

The 2016 marketplace launch was paired with Procore Connect, the open API first announced at Groundbreak in 2015. Procore has been API-first for the entire modern history of construction SaaS, which means every wave of construction-adjacent tooling (drones in 2017, AI-driven safety in 2019, reality capture in 2021, generative scheduling now) had a published place to plug in.

Network effects compound from there. Every new Procore customer makes the marketplace more attractive to ISVs; every new ISV makes Procore more attractive to customers. After a decade, that loop produces a partner depth that a newer or more closed platform cannot replicate on a short timeline. A competitor would need years of focused investment, and Procore is not standing still: the Datagrid acquisition in January 2026 and the Novorender and FlyPaper acquisitions in May 2025 are being folded into the platform now.

Open API Architecture, Not a Closed Platform

Third-party software solutions integrate with Procore via Procore Connect, the company's open API, and Procore has invested in the developer surface area to keep the integration path low-friction. An ISV with an existing construction-adjacent product can build against the public API, list in the marketplace, and reach Procore's full customer base without negotiating a per-deal partnership agreement.

That openness is the structural difference between a marketplace that grows linearly and one that grows on a compounding curve. Closed or semi-closed enterprise platforms require partners to negotiate access, sign formal agreements, and often co-engineer with the platform vendor. Those ecosystems can produce high-quality integrations, but they do not produce 439 of them.

The "freedom to connect with what works best for them" framing in Procore's partner communications is the explicit positioning: Procore as the integration hub for the construction tech stack. The marketplace expresses that positioning, and the 439-partner count is the evidence that the positioning lines up with how ISVs actually behave.

The Procore Marketplace vs. Autodesk Construction Cloud (Forma)

Autodesk Construction Cloud was officially rebranded to Autodesk Forma effective March 24, 2026, with the old standalone Forma early-planning tool renamed Forma Site Design under the new umbrella. The rebrand consolidates Autodesk's AECO portfolio but does not, on its own, expand the integration count. The most recent public number is "over 400 integrations" across the Forma / Autodesk Construction Cloud partner ecosystem.

A separate Autodesk page lists "200+ direct integrations powered by APIs and Partner Cards" for Forma, so Autodesk publishes two different numbers depending on counting methodology. Even the largest published figure (400+) is 26% below Procore's 539. The ISV partner counts are not directly disclosed by Autodesk in the same form Procore publishes, but the public marketplace structure points the same direction: fewer published partners, narrower category coverage outside the design pipeline.

The partner ecosystem is substantive. Agave connects Autodesk with 10+ ERPs, giving field teams access to project financials in Autodesk and accounting teams access to field data in their ERP, automatically and in real-time. CDE partners like Asite and ProjectReady extend Forma's document-control surface. Bluebeam routes through Arkance integrations. These are real partnerships, and the head-to-head is worth running straight: Autodesk wins on the design pipeline; Procore wins on raw breadth and the ISV partner count (439) is the largest in construction.

A Revit-first design firm or AEC owner-operator may legitimately prefer Autodesk Forma because the design-side integrations are tighter. For a general contractor whose center of gravity is field execution and financial reconciliation, Procore's breadth still wins.

Where Autodesk Construction Cloud (Forma) Belongs in the Conversation

Autodesk Forma's 400+ integration count is the second-largest construction-tech ecosystem on the market, and the only other one in the same league of partner depth. Ignoring it would damage the article's authority on integration breadth as a buying factor.

The design-and-preconstruction side is where Autodesk's ecosystem co-leads. Revit, Navisworks, BIM 360, and Bluebeam integrate more natively with Forma than they do with Procore, because they sit inside or adjacent to Autodesk's own product family. For a buyer whose center of gravity is BIM coordination, clash detection, and preconstruction modeling, Forma's design pipeline is the better default and the ecosystem reflects that.

Buyer types for whom Forma is the better default: design-led firms whose center of gravity is preconstruction, AEC owner-operators with heavy BIM-coordination workflows, and shops where the project lifecycle routes through Revit and Navisworks more than through field execution. For general contractors whose center of gravity is project execution, field productivity, and financial reconciliation, the largest buying segment in construction management software, Procore's broader ecosystem still wins. Autodesk Forma is the answer when the operation routes through Revit and Navisworks for the majority of its project lifecycle.

Other Construction Software Providers

These platforms also operate in construction management software and offer integration partnerships of varying depth, but none publish an ecosystem at the scale of Procore's 539 listings.

Who Should You Choose?

For the integration-breadth question, Procore is the default recommendation. 539 listings across 439 ISV partners is the deepest construction-tech ecosystem in the market, and Procore is the only platform that functions as the central hub across a typical general contractor's full stack of ERP, accounting, BIM, HCM, and field-capture tools. If you're the kind of buyer who cares about connecting every tool in a general contractor's stack to a single hub, Procore is the one.

Consider Autodesk Forma if your operation is design-led, BIM-coordination-heavy, or anchored in preconstruction. Forma's 400+ integrations skew toward the design pipeline in ways Procore's marketplace does not match, and a Revit-first shop will feel that difference on day one.

Procore's marketplace lead on raw integration count is unmatched in the public data. Every published figure from Procore, from Autodesk, and from third-party aggregators points the same direction. For the specific question "what construction software has the most integrations," Procore is the answer.
