What is Merge?
Merge's Gateway adds text-to-video routing as the connector catalog expands into enterprise verticals
Merge is shipping weekly across three product lines: Gateway (AI model routing), Unified (data sync abstraction), and Agent Handler (connector tooling for AI agents). Gateway added text-to-video generation through fal.ai and Interfaze web search alongside seven new LLMs including Claude Fable 5.1 and Gemini 3.8 Flash. Agent Handler's connector catalog now includes Goldcast (73 tools), Luma (67 tools), and enterprise verticals like Clio, Avalara, and Nextech Practice+.
What is Retool?
Retool ships a CLI, opening code-first app development and CI/CD pipelines
Retool has been expanding on two fronts: AI integration and developer tooling. The CLI launch lands alongside a regular cadence of self-hosted updates and model additions, signaling that Retool is building infrastructure for enterprise teams that want both AI-assisted app development and code-controlled deployment workflows. The self-hosted track (4.34 stable, 4.58 Edge) maintains a separate release cadence for on-premise customers.

Merge's Gateway adds text-to-video routing as the connector catalog expands into enterprise verticals
◆ Current state
Merge is shipping weekly across three product lines: Gateway (AI model routing), Unified (data sync abstraction), and Agent Handler (connector tooling for AI agents). Gateway added text-to-video generation through fal.ai and Interfaze web search alongside seven new LLMs including Claude Fable 5.1 and Gemini 3.8 Flash. Agent Handler's connector catalog now includes Goldcast (73 tools), Luma (67 tools), and enterprise verticals like Clio, Avalara, and Nextech Practice+.
◆ Where it's heading
Merge is moving beyond integration abstraction into full AI infrastructure. Gateway is no longer just an LLM router — it handles text, video generation, and web search through a single endpoint. Agent Handler's file-transfer-by-reference capability across SharePoint, Outlook, Gmail, and Drive removes a fundamental friction point where large files had to pass through conversation context. The connector expansion into events, legal, and healthcare suggests vertical market acceleration beyond the developer-first base.
◆ Prediction
Image generation routing to Gateway seems like the next logical multimodal addition. The connector catalog is growing fast enough that quality controls — rate-limit handling, edge-case robustness — will increasingly matter as much as new additions.

Retool ships a CLI, opening code-first app development and CI/CD pipelines
◆ Current state
Retool has been expanding on two fronts: AI integration and developer tooling. The CLI launch lands alongside a regular cadence of self-hosted updates and model additions, signaling that Retool is building infrastructure for enterprise teams that want both AI-assisted app development and code-controlled deployment workflows. The self-hosted track (4.34 stable, 4.58 Edge) maintains a separate release cadence for on-premise customers.
◆ Where it's heading
The CLI is the clearest directional signal: Retool is moving away from a browser-bound, GUI-first builder toward a tool developers can embed in existing code workflows. Iframe embedding expands where Retool apps can live; frontier model additions keep AI features current. Together these moves position Retool to compete in engineering-led organizations that previously ruled it out on tooling grounds.
◆ Prediction
Deeper git and CI/CD integration examples are likely to follow the CLI — a CLI release is usually the first piece of a code-as-infrastructure story. AI model additions will continue on the visible 2–3 week cadence, tracking the frontier model release cycle.
