OttoKit
OttoKit keeps widening its WordPress trigger surface one plugin at a time
A side-by-side editorial comparison of Customer.io and Eleventy — release velocity, themes, recent moves, and the top alternatives to consider.
Customer.io spent the summer pushing messaging off the screen and into location, time, and the lock screen
The summer release cycle put more than ten features into the product, and the coherent ones are about context rather than content: geofences trigger workflows when someone enters or leaves a physical location, live notifications render as iOS Live Activities and Android Live Updates, date triggers now read attributes on custom objects, and a notification inbox retains pushes. Around that sits infrastructure work — SMS via Sinch, Infobip and Vonage, multiple mobile apps per platform in one workspace, send-rate controls on automations — and an LLM actions surface where knowledge sources can be attached once and reused across prompts. The most recent entry is editor ergonomics in Design Studio.
The v4 canary line is being renamed Build Awesome while 3.x is kept on pure maintenance.
Two lines run in parallel. The 3.x branch gets dependency-only releases — 3.1.5 and 3.1.6 explicitly ship no core code changes, after 3.1.3 and 3.1.4 failed to publish and were left as immutable dead tags. The v4 alpha train, meanwhile, is where the work is: Node minimum raised to 22.15, page.inputPathDir and page.dir removed, batched incremental builds added, and a large refactor of the Nunjucks fork onto a fully-async prerelease. The releases themselves now carry the Build Awesome name and offer an @awesome.me/buildawesome install alongside @11ty/eleventy@canary.

The platform is expanding the set of things that can start a message and the set of places one can land, which is a different axis from the segmentation-and-copy tooling most of this category competes on. Geofences and live notifications both take work that previously required a specialist vendor or custom device code and make it a workflow primitive. The LLM actions work is following the same instinct — reusable knowledge sources are the beginning of prompt infrastructure rather than a prompt box — but it is the least developed of the threads. Meanwhile send-rate control and multi-app support read as enterprise deployment blockers being cleared.
Expect the location and live notification surfaces to gain the operational controls that continuous device features require, and the LLM actions path to keep accreting reusable pieces. Design Studio is receiving steady editor polish, so a broader component authoring release is plausible.

v4 is accumulating breaking changes faster than it is stabilizing — three of the entries in this window announce removals or minimum-version bumps, and alpha.10 exists only to hotfix a regression alpha.9 introduced. The Nunjucks refactor is the biggest bet: making the fork fully async removes the need for async-specific template tags, but the release notes flag it as risky for existing Nunjucks users. The naming change is proceeding on the same timeline, so users tracking canary are absorbing an identity shift and an API shift at once.
Expect more v4 alphas carrying breaking removals before any beta, with the Nunjucks async refactor generating follow-up regressions; 3.x looks likely to keep receiving dependency-only patches with no core changes.
