Building locally: Development tools that power the workflow
For WordPress agencies, developing locally is a key part of the process. Building and testing sites in a local setup means you’re not risking changes on the live site or staging environment. The right tools make this step quicker, safer, and more flexible for everyone on your team.
Let’s highlight three tools and see how they streamline modern WordPress development.
DevKinsta
DevKinsta allows teams to create local WordPress sites with just a few clicks. Each project runs in its own Docker container, and you can customize PHP, Nginx, and MySQL settings to closely mirror production. Built-in features like Adminer, log access, and email testing are included to make development easier.
One standout feature is its integration with Kinsta hosting. Once you’re satisfied with your local build, you can push it directly to a staging environment, reducing feedback cycles and eliminating messy file transfers.
WP-CLI
WP-CLI puts the power of the command line into WordPress management. You can install plugins, update settings, manage users, and handle migrations—all by running scripts instead of clicking through the dashboard.
Agencies use WP-CLI to automate repetitive tasks across multiple sites, saving time on bulk updates and ensuring processes are consistent as project volume grows.
WP Migrate
Transferring data between local, staging, and production sites can quickly become complex. WP Migrate simplifies these moves, letting teams send databases, media, themes, or plugins back and forth quickly—without risking broken data due to serialization issues.
When used together with DevKinsta and WP-CLI, WP Migrate completes a local workflow that’s both efficient and conducive to team-based collaboration.
Keeping things clean with version control and deployment pipelines
In a busy WordPress agency, clean code is non-negotiable. With developers often collaborating from different locations and time zones, structured version control and automated deployments make sure everyone stays aligned and launches are smooth.
Here are a few tools and processes that ensure code quality and dependable deployments.
GitHub and GitLab
Version control platforms like GitHub, GitLab, and BitBucket are indispensable for teamwork and tracking changes.
Branching, pull requests, and organized repo management mean teams can work simultaneously without stepping on each other’s toes. Isolating new features or bug fixes, reviewing code, and clear tagging all help minimize errors and keep releases orderly.
Through pull requests, developers can inspect, discuss, and approve code before it hits staging or production, maintaining both code integrity and accountability.
CI workflows
After code review, continuous integration (CI) pipelines handle routine tasks automatically. These workflows catch small errors, build assets, and deploy updates with speed and reliability.
For WordPress, this might involve:
- Running PHP linters for syntax errors
- Building out SCSS or JS files
- Exporting themes or plugins
- Deploying to a staging environment
- Notifying the team via Slack when the process completes
This keeps your launches reliable, minimizes manual mistakes, and ensures every update travels the same safe path to production.
GitHub Actions + Kinsta API
A growing number of agencies rely on GitHub Actions for customized deployment pipelines, with the benefit of native integration in GitHub itself.
Pairing Actions with the Kinsta API streamlines deployments—branches get deployed to staging automatically, post-deploy scripts can update databases or clear caches, and notifications or logs reach the team instantly in Slack. This end-to-end automation reduces manual work and frees developers to focus on what matters most.
Design and prototyping
Design leads the way in agency projects. The right wireframing and prototyping tools help turn concepts into actionable project plans, keep stakeholders aligned, and make transitions from design to development seamless.
Below are some of the main design tools that keep agency projects moving efficiently from sketches to final launch.
Figma
Figma has become the go-to design app for WordPress agencies. Operating in the cloud, it enables real-time collaboration and lets teams seamlessly move from wireframes to polished UI systems.
The component-based approach in Figma meshes nicely with block themes, making it easy to reuse and maintain design patterns for quicker project turnarounds.
Zeplin, Studio, and MarkUp
Transitioning from design to development gets easier with bridge tools.
Zeplin stands out by offering developers precise specs on spacing, typography, assets, and code snippets ready for implementation.
Studio (by Ceros) empowers teams to build and launch interactive digital experiences with minimal developer input—great for engaging, dynamic content.
MarkUp.io streamlines gathering feedback: clients and colleagues can comment directly on live sites, images, videos, or design previews, which enhances collaboration and clarifies requests.
Together, these tools help agencies deliver visually accurate themes and interactive features, closing the gap between design and ready-to-ship code.
Frameworks, starter themes, and custom builds
When building custom solutions, agencies don’t rely on generic themes. Instead, they turn to frameworks and internal systems to keep code organized, maintainable, and scalable, laying the groundwork for high-quality WordPress projects.
Sage
Sage is a preferred starter theme for WordPress pros. It introduces modern development standards with features like Blade templating, well-structured files, and a contemporary frontend setup using Laravel Mix or Vite.
Often, Sage gets paired with Bedrock, which brings dependency management, cleaner configuration, and a robust folder structure. This duo provides a professional-grade environment that maintains code clarity and ease of scaling.
For plugins, teams often use the WordPress Plugin Boilerplate, providing a simple, standardized setup for developing reusable features across projects.
Underscores (_s)
Not every project requires a heavyweight framework. For those needing a lightweight foundation without extras, _s (Underscores) remains a reliable starter theme.
With just enough code to jumpstart a custom theme and thorough documentation throughout, Underscores is ideal for smaller projects or solutions that require minimal overhead and total flexibility.
It’s particularly helpful when the client’s design system is tightly defined and speed or simplicity is a priority.
Custom internal frameworks
As agencies scale, many develop internal frameworks—bespoke themes, libraries, and processes—to fit their particular workflow. These in-house systems commonly include:
- Modular layouts using ACF, Gutenberg, or custom block options
- Prebuilt tools for SEO, caching, and accessibility
- Architectures ready for JAMstack or React-based frontends
- A design system closely synced with Figma components
Such frameworks do more than save time—they help agencies ensure a consistent product, reduce errors or tech debt, and differentiate themselves from competitors.
Collaborating with clients and managing retainers
The backbone of ongoing agency success is strong client communication. For retainer-based relationships, it’s about staying transparent, clear, and adding value. The right tools make all of this much easier.
Project management: Clarity across the board
Agencies depend on Trello, ClickUp, and Asana for task tracking, project updates, and client visibility—no need for long email chains. ClickUp is a robust workspace, while Trello excels at simple, visual task flows for smaller groups.
Tools that keep clients in the loop
Staging environments are vital for agency workflows. With platforms like MyKinsta, every site comes with a dedicated staging area, making it easy to review changes and test features safely before they go live.
Many agencies also set up dashboards showing site uptime, update history, security scans, backups, and analytics. Clear, regular reporting—either in real time or monthly summaries—demonstrates ongoing value and keeps clients engaged.
Support systems for high-touch clients
Quick, direct support is a must for clients who need extra attention. Agencies turn to tools like Help Scout or Zendesk. Others open shared Slack channels, making approvals and real-time problem-solving simple. These tools help maintain low response times and strong relationships—without overburdening your staff.
Automation and quality assurance
Scaling up requires automation. This preserves code quality, catches issues before they hit production, and frees up your team for more important tasks.
Automated testing catches issues before they go live
Automated testing is crucial for custom development. Unit tests make sure features work, while regression and visual testing flag any issues from updates. Even straightforward smoke tests can stop problems before users find them.
CI/CD tools
CI/CD solutions take charge of moving code to production. GitHub Actions, Bitbucket Pipelines, and Buddy can automatically:
- Run test suites
- Compile assets
- Deploy to staging/live environments
- Clear caches and update your team on progress
These workflows can be triggered by pull requests or set scheduling. They ensure reliable, repeatable rollouts—minimizing risk and saving time.
Partnering these with the Kinsta API lets agencies automate tasks like updating staging deployments or purging cached content after releases, further streamlining delivery.
Browser testing
Your sites need to look sharp everywhere: mobile and desktop, all major browsers. Automated browser testing platforms can help you cover all bases.
Tools like Ghost Inspector, BrowserStack, and LambdaTest enable agencies to run scripted, visual checks across a variety of device and browser configurations. Schedule routine tests to:
- Check forms and confirmation flows
- Verify checkout and cart experiences
- Ensure modals and navigation components function correctly
- Catch design inconsistencies or display bugs before go-live
This level of testing helps uncover subtle issues—like a sticky header malfunction or JavaScript error on specific devices—before your users do.
Hosting partnerships that support the stack
Strong hosting is the bedrock of every great tech stack. A reliable, high-performance hosting environment isn’t just essential stability—it should enhance developer operations and simplify site management for the team and clients.
The right host does more than serve up pages. It supports your development life cycle and helps you deliver better outcomes across the board.
Kinsta is built for agencies that build for others
Kinsta remains a popular choice for its focus on powering agency workflows. Partnering with a host like Kinsta gives teams access to tools that support every phase, from local builds to production launches.
