Snag AI vs Fieldwire: Best Fieldwire Alternative UK Sites

If your main job is finding and reporting defects quickly, Snag AI is built for that one task and nothing else. If you need to run tasks, RFIs, drawings, scheduling and snag lists for a whole project team, Fieldwire is the broader platform, at a cost that rises with every user you add.

Snag AI

Snag AI is a snagging tool first. You photograph a defect on site and the app logs it, writes a professional description, and tags the trade, location and severity for you. It also finds other snags in the same photo, so a cracked tile and a loose skirting board in one shot both get picked up.

Reports come out as formatted, client-ready Word documents, ready to send without reformatting. It works offline on site, which matters on basements, plant rooms and new-build sites with patchy signal, and snags upload automatically when you're back in range. It's available as an iPhone app and a web app, free to start with unlimited manual snags, with Pro at 19.99 GBP a month.

Good for:

• Site engineers and MEP engineers doing daily walk-rounds who need a fast, accurate record without typing out descriptions
• Clerks of works and independent snaggers producing formal reports for clients or developers
• Project managers and QSs who need consistent, professional snag reports without training a team on a complex platform
• Anyone snagging alone who doesn't need task assignment, drawings or scheduling

Less suited to:

• Large project teams who need to manage RFIs, drawing version control and scheduling in one place
• Sites where snags must be pinned directly to a markup drawing rather than tagged by location
• Teams already paying for a full project management platform and only need snagging as one small part of it

Fieldwire

Fieldwire is a wider jobsite management platform rather than a dedicated snagging tool. It's designed to bring everyone on a project, from site foremen to the project manager, onto one platform to coordinate work and share updates in real time. Snagging sits inside a bigger toolkit alongside tasks, snag lists and inspections, tracking everything that needs completing and recording defects or on-site issues.

Reviews suggest it's mainly used by project managers, field engineers and site supervisors for day-to-day task coordination and punch lists, with architects, estimators and owners dipping in to check plans, timelines and open issues. That breadth is the point: drawings, RFIs, scheduling and messaging all live in the same app as the snag list.

Logging a defect in Fieldwire means pinning it to a drawing or project location and writing it up yourself, there's no automatic description or tagging. Core features include task management, drawing markups with version control, and photos linked to specific plan locations, plus customisable reports, punch lists and inspection checklists. Core features work offline, with new data syncing once the app reconnects.

Pricing is per user rather than a flat subscription. Basic is £0, Pro is £33 per user/month, Business £54, and Business Plus £76, all billed annually. That's manageable for a small team but scales up quickly once you're inviting subcontractors or a wider site team onto the project.

Good for:

• Project managers running a whole site's task list, drawings and RFIs in one platform
• Teams who want drawing version control and markup alongside their punch list
• Owners and architects who need visibility across timelines and issues, not just defects
• Larger contractors who can absorb per-user costs across a big team

Less suited to:

• Solo snaggers or small teams who only need defect reporting, not full project management
• Anyone who wants a description written automatically rather than typing each entry
• Independent snaggers and clerks of works on a budget, where per-user, per-month pricing adds up fast for occasional use
• Sites where a quick client-ready Word report matters more than an in-app punch list

Which one should you pick?

If snagging is your whole job, or close to it, Snag AI gets you from photo to client-ready report with far less admin, and the free tier lets you try it with unlimited manual snags before paying anything. If you're managing a full project with drawings, RFIs and scheduling, and snagging is one part of a bigger workflow across a team, Fieldwire's broader toolkit may justify the per-user cost.

Many site engineers and clerks of works run Snag AI for the inspection and reporting side even when a wider platform handles tasks and drawings elsewhere. If you're setting up a snagging routine from scratch, our new-build snagging checklist covers the rooms and services most people miss, and our guide on how long you have to report snags on a new build explains the timescales that make fast, accurate logging worth getting right from day one.
