The short answer
Asite is a cloud common data environment (CDE) for sharing documents, models and workflows across everyone on a project, and it has been extending into project controls. Mastt is project controls software built for owners, owner's reps and project management consultants: budgets, contracts, payments, risk, schedule and reporting across one project or a whole program.
The two are not mutually exclusive. Some teams use a CDE for information governance and Mastt for owner-side cost, risk and reporting.
Side by side
Reviewed November 2026. Asite details come from Asite's website and Capterra. Mastt details come from our pricing page.
Key differences
Asite starts with information: a shared environment where documents and models are governed across every organisation on a project, now extended with project controls. Mastt starts with project controls and keeps documents light.
Asite is strongest at keeping the right version of the right file in front of the right party. Mastt turns budgets, contracts, variations and payments into forecasts and reports the owner can act on.
Capterra reviewers give Asite 3.2 out of 5 for ease of use and often mention the training it takes. Mastt is designed as a lighter, simpler alternative to traditional PMIS platforms, and you can start free.
Asite's Virtual Coworkers add AI agents to the CDE for information management, project controls and health and safety, and are in beta. Agent by Mastt handles cost, contract and reporting tasks that you delegate by email.
Being straight with you
If information governance is your biggest problem, Asite is the stronger fit, and Mastt is not trying to replace it.
Mastt does not replace these. It focuses on what the client side has to control: budget, contracts, variations, payments, risk, schedule and reporting.
Better together
The two can sit side by side on the same program. A common data environment such as Asite governs documents and models for the whole project team. The owner's team uses Mastt to track budgets, contracts, variations, payments, risk and schedule, and to report to stakeholders. Mastt offers pre-built integrations, such as Power BI and accounting platforms, and custom integrations on request.
Reviews
3.7 / 5
123 reviews on Capterra
Reviewers praise document control, search and version handling, responsive support, and workflow tools such as RFIs and markup. Common complaints are a dated or cluttered interface, a steep learning curve and complicated reporting. Many reviews are from 2018 or earlier, and some use the former name Adoddle, so they may not reflect the current product.

Mastt has far fewer reviews, so its higher score is less certain than Asite's. Read them on Capterra, or see how owner's reps and PM consultants use Mastt in our customer stories.
FAQ
For owners, owner's reps and project management consultants who mainly need cost, contract, payment, risk, schedule and reporting control, often yes. If your main need is a common data environment with BIM and ISO 19650 support, Asite is the better fit.
Asite is a cloud common data environment for construction, engineering, government, property and architecture projects. It manages documents, models and workflows, and adds a PMIS, a procurement marketplace and AI add-ons.
Asite offers Project Financials and Contract Management add-ons, and has launched a PMIS that brings cost, schedule and risk data into one record. Some Capterra reviewers describe its cost tools as simplistic. Mastt's cost module is built for owners, so compare both on your own project data in a demo.
Asite sells tiered editions and add-ons, does not publish a full price list and lists no free trial, so ask Asite for a quote. Mastt publishes its pricing: Starter is free for your first project with unlimited users, Professional averages $165 per project per month, and Enterprise and Agent are custom quotes.
Yes. A common data environment governs documents and models, while Mastt covers the owner's cost, risk, schedule and reporting. Mastt offers pre-built and custom integrations.
No. Mastt is not a common data environment or a BIM tool. If you need ISO 19650 information management or 3D model coordination, that is where Asite is strongest.
