      AI Development Review from Julia Antoci

      Leanware built the mobile MVP of our AI fitness assistant for iOS and Android. It started with discovery workshops that sharpened the product vision and shaped an MVP roadmap prioritizing launch features while leaving room for expansions like avatars and real-time feedback. They developed a conversational AI engine with custom prompt and context engineering tailored to fitness conversations, one that keeps continuity across sessions, remembers user progress and preferences, and keeps health guidance within safety standards. On top of that they implemented photo-based food recognition, smart search that understands fitness intent, personalized recommendations, progress tracking with AI-generated insights and coaching suggestions, and gamified response formats that make AI answers easy to read, plus the scalable backend behind it all. Their consultation saved us an estimated 20 to 30 percent in costs by avoiding unnecessary complexity, and we launched a functional MVP across the app stores in under eight weeks, faster than planned. Project management was exceptional: clear timelines, on-schedule delivery, and proactive communication via Slack, with expert recommendations guiding decisions rather than every choice being pushed back to us. Their technical skill and creativity made the whole thing feel less like hiring a vendor and more like building with a co-founder.

      Software Development Review from Anonymous

      Leanware delivered two significant projects for our e-commerce platform along with a steady stream of smaller fixes and enhancements. They built a new employee management page in our back office so our customers can create accounts, set permissions, and link employees to entities on their own, and when our mobile app's chat functionality needed replicating in the back office, they built a custom chat and messaging React library from scratch, integrated seamlessly with our design system and existing bespoke solution. Along the way they worked comfortably across Next.js, React, React Native, Apollo, GraphQL, and Hasura, and adapted to our implicit conventions. We ran week-long SCRUM sprints with check-ins three times a week, and they consistently hit the sprint goals on time; even when we needed hard pivots mid-sprint, they adapted without losing pace. As the engagement progressed they increasingly took the lead, asking well-informed questions and offering suggestions on code, product, and design that genuinely enriched the outcomes. What impressed us most was how swiftly they onboarded: given incomplete product descriptions, they asked the right questions to fill the gaps and picked up our undocumented code patterns without getting stuck on minor details. It felt like one cohesive team working toward shared objectives, free of the friction that usually comes with a third party

      Mobile App Development Review from Anonymous

      Leanware has partnered with us since Q4 2023 on two cloud-based mobile apps for iOS and Android, one built in Flutter and one in React Native, handling development on both and the UI/UX design on one. For one project they staffed a team of five mid-level developers, a senior developer, an architect, and a UX designer available as needed. They also took over an app that was unstable and nowhere near production-ready and turned it into a stable, solid product I'm genuinely proud to show. Their processes leave nothing to chance and the code that comes out of them is excellent; they've been flexible and thorough throughout. They meet deadlines, keep their promises, and are careful about what they commit to. The whole team has been great, and Alvaro, their Technical Product Manager, deserves a special mention for being remarkable. I hired them because they were upfront about what they could and couldn't do, and that honesty, together with the tremendous quality of their work, is what separates them from other providers. Both are getting harder to find these days.

      Software Development Review from Lori Feld Oakley

      Our Services organization is scaling quickly and we urgently needed a custom software application to automate our workflows, without breaking our annual budget. CodeStringers was the perfect fit, supporting us from ideation through go-live and everything in between. They innovated, hit their deadlines and released an amazingly high quality application that decreases our internal costs and improves our reputation with our customers. It would not have happened without CodeStringers.

      Enterprise Review from Christian Schraga

      CodeStringers is the perfect outsourcer to call If you have a solid software business idea but don’t know exactly how to bring it to life. They have both a top-notch development team as well as an executive staff with expertise in marketing, finance, and general business acumen. So they can not only build a product for you but they can make sure that the product you want to build is likely to succeed in the marketplace.

      We partnered with &above on a joint client project, where they led design and development while we handled content strategy and SEO. The experience was smooth throughout. Their design work was sharp, their dev execution was clean, and they were easy to work with as a cross-functional partner. Would happily collaborate again and recommend them to any brand looking for a strong creative and technical team.

Frequently Asked Questions About Headless CMS Companies

What are the typical services provided by headless CMS developers?

Headless CMS companies plan, implement, and operate a headless content management system (CMS), so teams can efficiently publish content across websites, apps, and other digital channels. Typical headless CMS development services include: 

  • Headless CMS consulting and strategy: Advising businesses on the best headless CMS vendor and architecture or optimizing current platforms to meet their goals.  
  • Platform migration: Moving content and assets from legacy systems while preserving data integrity, security, and SEO with minimal downtime. 
  • Custom headless CMS development: Building the content models, automations, and user roles as well as the front and back end to ensure easy maintainability and reliable performance. 
  • API and plugin development: Integrating the headless CMS platform with third-party systems, such as payment gateways, CRMs, ERPs, and marketing automation tools. 
  • Ongoing maintenance and support: Continuously monitoring the platform's performance, resolving issues, installing security patches and updates, and managing infrastructure. 

What is the difference between headless CMS and traditional CMS?

A headless CMS separates the content management backend from the frontend experiences. As such, content is delivered via APIs to any channel (websites, mobile apps, and IoT devices), so teams can reuse the same content across multiple experiences. 

On the other hand, a traditional CMS has a unified back- and front-end (monolithic), meaning that there is a single interface that often comes in the form of a website. It can still power multiple channels, but doing so requires extensive tooling and customization. 

Here are more details on their differences: 

 Headless CMS platformsTraditional CMS platforms
Advantages
  • Tech agnostic, allowing teams to use any framework
  • Consistent omnichannel experiences due to API-first approach
  • Highly collaborative, allowing for developer, content, and marketing teams to work simultaneously
  • Cost effective due to the availability of pre-built solutions (WordPress, Drupal, etc.) and templates 
  • User-friendly, allowing teams with limited tech knowledge to configure
  • Faster time-to-market launch
Disadvantages
  • Higher build complexity 
  • Requires technical expertise 
  • Potentially more expensive to develop 
  • Slower initial setup but faster iteration cycles
  • Less front-end flexibility 
  • Omnichannel needs extra work 
  • Scalability for multiple experiences can be difficult 

What are the most common headless CMS platforms?

Based on our research, here are some of the most common headless CMS platforms that developers use: 

  • WordPress: While it is a traditional CMS, it can be converted into a headless platform when paired with a modern JavaScript framework. Use this platform if you already have an existing WordPress-based site and want to migrate to a headless one. 
  • Strapi: An open-source, self-hosted headless CMS, enabling teams to have higher control over their data and infrastructure while being able to customize plugins, APIs, and workflows. Choose Strapi if you want to keep your data within your servers, and data sovereignty is non-negotiable. 
  • Contentful: A digital experience platform (DXP) with an API-first architecture and an extensive library of pre-built integrations. This platform is common for enterprises with complex needs and legacy tools. 
  • Sanity: Known for its collaboration features and flexible content management, Sanity is ideal for businesses that prioritize agility through controlled yet automated workflows. 

While these are the most common platforms, reputable headless CMS companies will recommend a tech stack that best matches your goals, technical requirements, existing systems, operating models, team capabilities, and target audiences. 

What companies benefit the most from headless CMS?

Many organizations benefit the most from a headless CMS when they need to publish content to multiple digital channels, scale across regions, or build custom experiences without being constrained by a single website template system. Common scenarios include: 

  • eCommerce and retail with multiple customer touchpoints (web, app, in-store screens) and heavy integrations (PIM, inventory, CRM, marketing automation), where teams want faster experimentation and performance. 
  • Brands running omnichannel campaigns (web + mobile + social + email + in-product) that need to reuse content consistently across channels. 
  • Product-led or platform businesses building multiple front ends (customer portals, apps, partner dashboards) that require developer flexibility and frequent releases. 
  • Global enterprises managing multiple markets, languages, and brands—where content governance, localization workflows, and reusable components are essential. 

When should a company NOT use headless CMS frameworks?

A headless CMS may not be the best fit if: 

  • You need to launch quickly on a tight budget, and a template-based website will meet your goals. 
  • Your site is simple (e.g., a landing page or small brochure site), and you do not need multiple channels, complex integrations, or frequent changes. 
  • You do not have ongoing development capacity (in-house or via a retainer) to maintain the front end, integrations, and updates. 
  • Your team depends on visual page-building and WYSIWYG (what you see is what you get) editing and you are not prepared to invest in a headless setup that delivers an equivalent editorial experience.
