Solidus vs Smile.io
A side-by-side editorial comparison of Solidus and Smile.io — release velocity, themes, recent moves, and the top alternatives to consider.
Solidus vs Smile.io: at a glance
What is Solidus?
Solidus builds out its new admin with product properties and store credits
The visible activity is on solidus_admin, the project's next-generation admin interface, which at v0.4.0 added a product-properties create/edit flow, a store-credits show page, and order-email display. The work is steadily porting merchant-facing admin functionality into the new UI.
What is Smile.io?
Smile.io leans on loyalty content and partner integrations to push retention
Smile.io's feed is mostly educational loyalty content aimed at DTC and mid-market brands — omnichannel loyalty, zero-party data activation, reviews-plus-rewards, and 2026 retention trends — interleaved with partner-integration co-marketing (Digioh, Judge.me) and the occasional integration launch like Smile x GoGenerosity. Publishing cadence is low and spread over months.
Solidus vs Smile.io: editorial side-by-side
Solidus
0.0E-COMM
Solidus builds out its new admin with product properties and store credits
◆ Current state
The visible activity is on solidus_admin, the project's next-generation admin interface, which at v0.4.0 added a product-properties create/edit flow, a store-credits show page, and order-email display. The work is steadily porting merchant-facing admin functionality into the new UI.
◆ Where it's heading
With only the new-admin line visible here, the direction is clear: incrementally rebuild the Solidus admin experience screen by screen toward feature parity with the legacy admin.
◆ Prediction
The next entries likely continue filling out the new admin with more merchant-management screens.
Smile.io
5.0E-COMM
Smile.io leans on loyalty content and partner integrations to push retention
◆ Current state
Smile.io's feed is mostly educational loyalty content aimed at DTC and mid-market brands — omnichannel loyalty, zero-party data activation, reviews-plus-rewards, and 2026 retention trends — interleaved with partner-integration co-marketing (Digioh, Judge.me) and the occasional integration launch like Smile x GoGenerosity. Publishing cadence is low and spread over months.
◆ Where it's heading
The strategy is positioning Smile as the retention layer in a stack of best-of-breed Shopify tools, sold through integration partnerships and education rather than a steady feature drumbeat. Expect more partner integrations that pair loyalty with reviews, data, and engagement tools, and continued thought-leadership content on retention economics.
◆ Prediction
Next moves likely continue the integration-partnership pattern (pairing Smile loyalty with complementary DTC tools) alongside retention-focused content; net-new product features aren't visible in this feed.
