Update activity

How busy the existing users are, measured as downloads in the last 30 days for every 1,000 active sites. A spike means a new release everyone's pulling; a long, slow decline means an aging user base that updates less.

Estimated value

What this plugin might earn a year, and what it might sell for. Modeled from public signals; we don't see anyone's books.

low confidence

Est. annual revenue

≈$81 range $24–$280

Est. acquisition value

≈$160 range $36–$700

A small install base leaves thin data to model from. A declining trend compresses what a buyer would pay. The range spans more than 10x because wp.org publishes install counts as broad bands, and conversion and price compound on top. Read the midpoint as an order of magnitude, not a valuation.

How we estimate this

Assumptions

  • Free → paid conversion. 0.5%–2% of active installs pay for the pro tier. Typical for freemium WordPress plugins; the real rate varies a lot by product.
  • Annual price per customer. $79–$199 a year, typical for Booking & Events plugins rather than this plugin's own pricing.
  • Acquisition multiple. 1.5x–2.5x annual revenue, the going range for small WordPress-plugin businesses, compressed because the install trend is declining.
  • Install base. 60–70 active installs, from our install estimate (wp.org only publishes the floor).

Revenue is installs × conversion × price; value is revenue × a typical acquisition multiple. Every factor is an assumption band, so the output is a wide range on purpose. If you're buying or selling, treat this as a starting point for due diligence.

    It’s just well thought out! It’s very easy to setup an event page and configure it how you want. The interface is clear and simple, and everything is built on top of Gutenberg, which gives it a nice native experience. The support is also awesome! I noticed a bug, and it was resolved within hours with a new update!! Ah yes, and no overly intrusive prompts to make you buy the premium version (the cherry on the cake)

    I’m definitely using EventKoi for all my upcoming event calendar needs. The setup wizard was quick and the whole interface is intuitive. The pages load fast and error free. The author looks to be creating a simple, clutter free alternative to the existing ones and seems to be getting it right.

    Simple, clean, and easy to use. Enough features to make it flexible, but not so many features that the add/edit screen feels overwhelming. Immediately became my new favorite calendar plugin!

    Even though the WP event plugins market is packed, I find EventKoi’s interface to be simple, beautiful, and designed with the block-based editor in mind. Yet, it still has short-code support, so the classic theme can use it. The support team also responds to inquiries promptly. I received a reply within an hour after posting a bug report on the plugin forum, and within a week, they had a patch released.

    EventKoi Lite is simply amazing! The setup was effortless, and the interface feels clean and modern. I love how lightweight yet feature-rich it is — creating and displaying events has never been smoother. The performance and design both stand out. Definitely one of the best event plugins I’ve used on WordPress!

    EventKoi Lite is the new kid on the block when it comes to event plugins in WordPress. While many of the old school plugins have years of technical debt, EventKoi is a fresh start. It’s block-based first with support for shortcodes. Creating events is easy and straightforward. The user interface is a breeze to use and fits right in with the WordPress backend. Every free plugin seems to have an upsell to a pro version. This one is no exception. However, unlike many other plugins, the upsell here is done in a tasteful way. Overall, this product is a joy to use and it’s only just getting started. I’m looking forward to seeing what this becomes in the next few years.
