What is Solidus?
solidus_admin 0.5.1 patches two security advisories a month after the 0.5.0 feature release.
solidus_admin, Solidus's newer admin interface, shipped 0.5.0 in October with editors for tax rates, payment methods, stores, zones, stock locations and option types, plus a move from Geared Pagination to Kaminari. 0.5.1 follows with fixes for two GitHub security advisories, after 0.4.1 fixed a stored XSS earlier in October.
What is Subbly?
Subbly's AI builder becomes interruptible, months after retention intelligence moved in-house
Development is uneven across the product. The AI Builder is where the recent motion is: model intelligence was upgraded in June, and August makes the agent steerable mid-run — a new prompt can be queued while it works and gets inserted between steps rather than waiting for the current one to finish. The subscription platform itself has been quieter since spring, when Subbly replaced a third-party churn model with an in-house one it measures as 68% more accurate, added a cancellation type setting for immediate versus end-of-period, and shipped biometric two-factor with anomaly detection.
Solidus vs Subbly: editorial side-by-side
Solidus
5.0E-COMM
solidus_admin 0.5.1 patches two security advisories a month after the 0.5.0 feature release.
◆ Current state
solidus_admin, Solidus's newer admin interface, shipped 0.5.0 in October with editors for tax rates, payment methods, stores, zones, stock locations and option types, plus a move from Geared Pagination to Kaminari. 0.5.1 follows with fixes for two GitHub security advisories, after 0.4.1 fixed a stored XSS earlier in October.
◆ Where it's heading
The new admin is filling in feature coverage while receiving its first steady flow of security reports, a sign it is seeing real production use. Security patches are arriving roughly monthly.
◆ Prediction
Expect further 0.5.x security patches and more settings editors before a 0.6.0; the entries do not show its timing.
Subbly
2.5E-COMM
Subbly's AI builder becomes interruptible, months after retention intelligence moved in-house
◆ Current state
Development is uneven across the product. The AI Builder is where the recent motion is: model intelligence was upgraded in June, and August makes the agent steerable mid-run — a new prompt can be queued while it works and gets inserted between steps rather than waiting for the current one to finish. The subscription platform itself has been quieter since spring, when Subbly replaced a third-party churn model with an in-house one it measures as 68% more accurate, added a cancellation type setting for immediate versus end-of-period, and shipped biometric two-factor with anomaly detection.
◆ Where it's heading
The builder work is converging on keeping a person in the loop while the agent runs rather than making the agent more autonomous — the stated motivation is course-correcting a run that is going wrong and avoiding wasted credits. That framing, credits as the cost of a bad run, is worth noting: it treats agent time as a metered resource the merchant is spending, which shapes what gets built next. The retention side has not seen comparable investment since the churn model landed in May.
◆ Prediction
Expect further mid-run controls on the builder along the same line — editing or cancelling a queued step, or rolling back a bad one — since the credit-waste problem this release names is only partly solved by inserting prompts.
