What is Retool?
Retool layers enterprise governance and current AI models onto its app-and-workflow core.
Retool ships continuously across edge and stable self-hosted channels while extending its low-code core toward governed enterprise tooling. Recent releases add object-level permissions, app-to-workflow triggering, and current-generation model support. It reads less as an app builder now than as a platform for apps, workflows, and agents with controls attached.
What is Ably?
Ably is repositioning its realtime infrastructure as the transport layer for AI agents
Ably keeps shipping across its SDK matrix (JS, Java, Cocoa), but the center of energy is the AI Transport SDK, iterating fast from v0.3.0 to v0.5.0. Each release hardens realtime messaging for AI agents: declarative codecs and Presence/LiveObjects pass-through (0.3.0), external data hydration to stitch an app's own message store to the channel (0.4.0), and durable execution via a Step primitive that survives process restarts and retries in Temporal or Vercel's Workflow Development Kit (0.5.0). Core Pub/Sub keeps advancing too — React Native push and a LiveObjects path-based API.
Retool vs Ably: editorial side-by-side
Retool
6.3INFRA · APIS
Retool layers enterprise governance and current AI models onto its app-and-workflow core.
◆ Current state
Retool ships continuously across edge and stable self-hosted channels while extending its low-code core toward governed enterprise tooling. Recent releases add object-level permissions, app-to-workflow triggering, and current-generation model support. It reads less as an app builder now than as a platform for apps, workflows, and agents with controls attached.
◆ Where it's heading
The arc points at enterprise-readiness and agent-native tooling: role-based object permissions that cover agents, workflows callable from apps, and continual model refreshes all target larger, governance-conscious buyers. Data-source breadth—Microsoft Graph, Snowflake over the Postgres protocol—keeps widening what teams can build against.
◆ Prediction
Expect deeper agent governance and further model integrations as Retool positions its app-plus-workflow stack for regulated enterprise use.
Ably
5.0INFRA · APIS
Ably is repositioning its realtime infrastructure as the transport layer for AI agents
◆ Current state
Ably keeps shipping across its SDK matrix (JS, Java, Cocoa), but the center of energy is the AI Transport SDK, iterating fast from v0.3.0 to v0.5.0. Each release hardens realtime messaging for AI agents: declarative codecs and Presence/LiveObjects pass-through (0.3.0), external data hydration to stitch an app's own message store to the channel (0.4.0), and durable execution via a Step primitive that survives process restarts and retries in Temporal or Vercel's Workflow Development Kit (0.5.0). Core Pub/Sub keeps advancing too — React Native push and a LiveObjects path-based API.
◆ Where it's heading
Ably is extending its realtime-delivery guarantees into agent orchestration: exactly-once-feeling semantics for agent turns, durability across at-least-once retries, and shared read-only conversation views for client and agent. The bet is that AI apps need the same ordering, presence, and history primitives Ably already sells — repackaged for agent runs rather than chat messages.
◆ Prediction
Expect the AI Transport SDK to keep maturing toward a 1.0 with fewer breaking changes, more workflow-engine integrations beyond Temporal and Vercel, and continued path-based LiveObjects work across language SDKs. The realtime core stays on its steady incremental cadence.
