What is Retool?
Retool keeps compounding: model support, agent resources, and enterprise access control.
Retool is a maturing internal-tools platform shipping on a fast, disciplined cadence across three fronts: the new app builder, enterprise governance, and its Agents product. Recent releases mix routine self-hosted channel bumps with substantive additions like object-level permissions and new data connectors.
What is Merge?
A unified-API company is quietly rebuilding itself as AI-agent infrastructure
Merge ships dense weekly changelogs across three surfaces: the original Unified API (accounting, HRIS, ATS, CRM, file storage, ticketing), Agent Handler (governed tools and connectors for AI agents), and Merge Gateway (a model-routing and LLM-security layer). The Unified API work is steady maintenance — mapping enhancements, sync performance, and edge-case handling across dozens of integrations. The energy and net-new capability sit in Agent Handler and Gateway.

Retool keeps compounding: model support, agent resources, and enterprise access control.
◆ Current state
Retool is a maturing internal-tools platform shipping on a fast, disciplined cadence across three fronts: the new app builder, enterprise governance, and its Agents product. Recent releases mix routine self-hosted channel bumps with substantive additions like object-level permissions and new data connectors.
◆ Where it's heading
The clear direction is agent-and-AI-native internal tooling with enterprise controls to match. Adding Claude Fable 5, letting Agents query more resources (Presto), and shipping object roles all point to Retool positioning as the governed layer where teams build AI-backed internal apps, not just CRUD dashboards.
◆ Prediction
Expect continued model additions and expansion of what Agents can act on, paired with more granular enterprise access controls as larger customers adopt the agent features.

A unified-API company is quietly rebuilding itself as AI-agent infrastructure
◆ Current state
Merge ships dense weekly changelogs across three surfaces: the original Unified API (accounting, HRIS, ATS, CRM, file storage, ticketing), Agent Handler (governed tools and connectors for AI agents), and Merge Gateway (a model-routing and LLM-security layer). The Unified API work is steady maintenance — mapping enhancements, sync performance, and edge-case handling across dozens of integrations. The energy and net-new capability sit in Agent Handler and Gateway.
◆ Where it's heading
Merge is levering its integration catalog into an agent-tooling and model-routing play. Gateway keeps adding frontier models, custom routing, and enterprise controls (RBAC, audit, prompt-injection protection, DLP), while Agent Handler expands connectors and observability. The through-line: the same normalized-integration muscle that powered unified data access is now being pointed at giving AI agents governed, routable access to tools and models. Unified API is the stable base; the growth vector is agent infrastructure.
◆ Prediction
Expect Gateway to keep absorbing new frontier models and routing controls on a weekly cadence, and Agent Handler to keep converting existing Unified API integrations into agent-callable connectors.
