What is Gadget?
Gadget keeps its Shopify app platform in lockstep with Shopify's own release train.
Gadget is a full-stack development platform for building Shopify apps, and its changelog reads as steady platform maintenance: tracking new Shopify API versions, adopting Polaris web components, and hardening its own infrastructure. Recent work spans access-control UX, database rate-limiting, and a logging-backend migration. The pace is incremental with no single headline feature.
What is Merge?
Merge is turning its weekly integration digest into an agent control plane — the news is always at the bottom.
Merge publishes one dated digest a week, and the structure is consistent: unified Accounting, ATS, CRM, File Storage and HRIS reliability work up top, then Agent Handler and Gateway at the end, where the directional changes live. The feed now also carries per-product breakout entries (Gateway, Unified, Agent Handler) that restate the same week's items in more detail rather than adding new ones. The Agent Handler catalog carries hundreds of generic MCP connectors alongside Merge's own, on shared authentication and policy, and Gateway has been accumulating model coverage, routing controls and guardrails over the same period.

Gadget

Gadget keeps its Shopify app platform in lockstep with Shopify's own release train.
◆ Current state
Gadget is a full-stack development platform for building Shopify apps, and its changelog reads as steady platform maintenance: tracking new Shopify API versions, adopting Polaris web components, and hardening its own infrastructure. Recent work spans access-control UX, database rate-limiting, and a logging-backend migration. The pace is incremental with no single headline feature.
◆ Where it's heading
Two threads run through the feed: staying current with Shopify (API 2026-04, expiring offline tokens, TOML as the source of truth) and tightening platform reliability (progressive DB-query charging, surge-threshold visibility, a Loki-to-ClickHouse logging move). Gadget's roadmap is effectively coupled to Shopify's — its value is absorbing that churn so app builders don't have to.
◆ Prediction
Expect continued fast-follow support for the next Shopify API version and further reliability and observability work; the ClickHouse migration suggests more logging and metrics tooling is likely next.
Merge

Merge is turning its weekly integration digest into an agent control plane — the news is always at the bottom.
◆ Current state
Merge publishes one dated digest a week, and the structure is consistent: unified Accounting, ATS, CRM, File Storage and HRIS reliability work up top, then Agent Handler and Gateway at the end, where the directional changes live. The feed now also carries per-product breakout entries (Gateway, Unified, Agent Handler) that restate the same week's items in more detail rather than adding new ones. The Agent Handler catalog carries hundreds of generic MCP connectors alongside Merge's own, on shared authentication and policy, and Gateway has been accumulating model coverage, routing controls and guardrails over the same period.
◆ Where it's heading
The through-line is that Merge is repositioning from data plumbing to the layer agents pass through. Each week adds either reach (more connectors, more tools per connector, more models) or control (guardrails, per-project policy, access configuration). This window is reach-and-efficiency: the GitHub connector expanded to 145 tools, Outlook payloads were cut substantially, and Gateway guardrails became configurable per project rather than per account.
◆ Prediction
Expect the per-project granularity applied to guardrails to spread to the rest of Gateway's controls, and the connector catalog to keep absorbing hosted third-party MCP servers the way Axiom was added.
