Best Plugin Developers

We may earn a commission if you hire through links on this page, at no extra cost to you. How we choose picks.
A plugin adds a feature to an existing platform, such as WordPress, WooCommerce, Shopify, Figma or a browser. Custom plugins make sense when no existing plugin does what you need, or when existing ones are too heavy. Plugin projects go wrong when the plugin breaks with platform updates, conflicts with other plugins, or cannot be maintained after the developer leaves. This guide helps you commission a plugin that lasts.
We are finalizing our shortlist for this service. Until then, the guide below walks you through how to evaluate sellers yourself.

What a good plugin project includes
Plugin development gigs range from small tweaks to full-featured plugins. Check that the project states:
- Platform and minimum version supported.
- Features and settings.
- Compatibility with your theme and other plugins.
- Coding standards of the platform.
- Testing on a staging site.
- Documentation and source code.
- Support for platform updates.
Ask whether the plugin will store data in its own tables or settings, and what happens when it is removed. Good plugins clean up after themselves, while poor ones leave data behind or break the site when deactivated.
How to brief a plugin developer
- The platform and your version.
- What the plugin should do, step by step.
- Existing plugins you tried and why they did not work.
- Your theme and plugin list.
- Settings you want to control without code.
- Access to a staging copy of your site.
Give the developer a staging site, not your live site. It lets them test freely without risking your business, and it shows how the plugin behaves with your real theme and plugins.
Think about who will use the settings. If a non-technical team member will manage it, ask for clear labels and sensible defaults. A plugin that only its developer understands becomes a problem the day that developer is unavailable.
Ask how the plugin will handle performance. A plugin that loads extra code or makes slow requests on every page can make the whole site slower, which affects visitors and search rankings. Good developers load features only where they are needed, and they can show before-and-after speed tests on your staging site. Ask for those results as part of delivery.
What drives the price
- complexity and number of features
- settings and admin screens
- integrations with other services
- compatibility testing
- documentation
- ongoing support for platform updates
Ask about a small support plan for updates. Platforms release major updates regularly, and a plugin that is not maintained can stop working or become a security risk.
Red flags
- Code that ignores the platform's standards.
- No testing with your theme and plugins.
- Changes made directly on your live site.
- Unclear ownership of the code.
- No plan for platform updates.
Keep the plugin's source code and documentation in your own repository or storage. If the plugin needs a fix years later, you will be glad you can hand it to any developer.

Quick pre-order checklist
- I checked existing plugins first.
- The developer will test on a staging site.
- The plugin follows the platform's standards.
- I own the code and have documentation.
- I have a plan for platform updates.
FAQ
Should I buy an existing plugin or build a custom one?
Check existing options first. A well-maintained plugin is often cheaper and safer. Custom plugins make sense for specific needs or when existing ones are bloated or poorly supported.
Will the plugin break when the platform updates?
It can. Ask the developer to follow the platform's official guidelines and to explain how updates will be handled after delivery.
Can I sell the plugin later?
If you own the rights. Agree in writing that you receive full rights to the code written for you.
How is the plugin tested?
Ask for testing on a copy of your site with your theme and other plugins active, since conflicts are common.
What documentation should I get?
Installation steps, settings, how it works and how to update it.
