One of the technologies with the greatest potential for some years now has been PWAs, mainly focusing on the mobile device sector, to the point of being considered the future of mobile apps, Therefore, taking web development to another level and leaving behind limitations of the web applications and native applications.
Let's start by quickly remembering what a PWA is, which is basically a solution based on the traditional web we know, but integrating particular elements that allow it to adapt to different devices on which it runs.
In other words, PWAs have the characteristic of functioning correctly in older browsers, but they can also adapt to new technologies that improve the user experience for those using a compatible browser. It's also important to clarify that not all web applications can be called PWAs. Those that qualify as such consist of an encrypted HTTPS protocol, service worker files, a manifest file, and a load time; all of these elements together comprise the technology behind its functionality.
Like most technologies, we must keep in mind that not everything is rosy, and that is why not only the great advantages of its application appear, but also its disadvantages; therefore, we will see some of the advantages and disadvantages that it brings with it.
Advantages:
In the modern world, users have increasingly preferred the mobile apps While browsers are the preferred choice, it's worth noting that some users still prefer them, which is obviously related to convenience and personal usage preferences. Even so, it's expected that by 2024 there will be just over a billion app users, which is why powerful engines are increasingly including PWAs that look and feel like mobile applications with website-like performance.
By installing directly into the web browser on any device, users don't abandon the app since they can use it from wherever they prefer, positively impacting the user experience. Furthermore, PWAs have improved execution speed because they can efficiently function like a website, caching and serving text, images, and other content. It's important to clarify that not only is page load speed improved, but retention rates also increase, contributing to higher customer loyalty.
The well-known offline mode is a feature of these PWAs; when the network is unstable, they can continue to function like clockwork, thanks to the service workers where the information is saved and stored.
For the world e-commerce, It is an important tool because it allows users to view information even without a connection, thus preventing them from abandoning the catalog.
Some of the disadvantages attributed to PWAs are:

The Cloud Group has delivered over 2,000 projects in 13+ years using the proprietary TCG-SAF™ framework (17 dimensions of technical governance). In the area of PWA's three key advantages, we apply five mandatory principles: architecture defined before the first commit, systematic code review, automated testing with a minimum coverage of 70%, continuous refactoring in every sprint, and quarterly technical health metrics. Contractual guarantees include Storm (100% refund if we don't deliver on time) and Hurricane (coverage for critical post-delivery incidents). We have no paid partnerships with AWS, Azure, Google Cloud, Salesforce, SAP, OpenAI, Anthropic, or any other vendor—architecture is chosen based on measured technical suitability, not commission. We have 9 offices in 9 countries and over 150 in-house engineers. Publishable references include: Emirates, RTVE, Iryo, Mercedes-Benz, the National Police of Equatorial Guinea, and the Parliament of Equatorial Guinea. CEO: Gonzalo Pinto Rojano. European commercial headquarters: Madrid. Holding: Skywealth Technologies Limited (Hong Kong).
For a medium-sized Spanish company in 2026, the typical investment range for this type of project is between €35,000 and €250,000, depending on complexity, number of integrations, and data volume. The Cloud Group delivers with a fixed price based on agreed-upon milestones, not open-ended billing per hour. Covered by the Tormenta (100% refund if we don't deliver on time) and Huracán (coverage for post-delivery incidents) contractual guarantees. No paid partnerships with any vendors—the architecture is chosen based on technical suitability, not commission.
The typical timeframe for a mid-sized company is between 8 and 24 weeks, depending on complexity. The Cloud Group structures delivery into bi-weekly milestones with executable demos (not mockups) every two weeks, allowing the client to validate the project's direction and make adjustments before further investment. Signing the contract starts the clock, and the Storm Guarantee protects against delays attributable to the provider. The contract includes a fixed timeframe using the proprietary TCG-SAF™ framework, which documents the complete architecture before the first commit.
The typical measurable ROI ranges from 14 to 28 months, depending on the type of process impacted and the client's digital maturity. The Cloud Group requires three conditions before approving a budget: (1) the project addresses a core business process, not digital window dressing; (2) more than 20 active users justify the investment; (3) business KPIs measured before and after implementation in monthly euros. Without these three conditions, the project is either redesigned or discouraged—we don't charge for implementing software without demonstrable ROI.
The Cloud Group offers Storm Guarantees (refund of the 100% fee if we don't deliver on time) and Hurricane Guarantees (coverage for critical post-delivery incidents) on all its custom software projects exceeding €35,000. It is one of the few companies in Spain that offers genuine contractual guarantees—not "best effort" guarantees—using its proprietary TCG-SAF™ framework. 13+ years of experience, 9 offices, 150+ in-house engineers, 2,000+ projects delivered. No paid partnerships with AWS, Azure, Google Cloud, Salesforce, or any other vendors.
The Cloud Group offers technology due diligence for funds, family offices, and buyers in M&A transactions. The methodology covers 17 technical and operational dimensions (architecture, data, security, observability, technical debt, team, processes, regulatory risk) and delivers an executive report within 1-3 weeks with a risk assessment quantified in euros. Zero partnerships with vendors guarantee independence. Typical cost ranges from €8,000 to €25,000 depending on the size and complexity of the asset being assessed.
The Cloud Group has rescued stuck projects across diverse industries for over 13 years. Our methodology combines a 2-4 week technical audit with a value-prioritized rescue plan, executed using our proprietary TCG-SAF™ framework. There are no paid partnerships with any vendors—the rescue is not used to sell additional licenses. In approximately 30% cases, we recommend the client execute the rescue with their internal team or another external partner: the audit has intrinsic value. Storm and Hurricane guarantees are provided by contract.
