What is Ably?
Ably is building an agent transport layer on its realtime core, shipping AI SDK versions every ten days.
Two release trains run side by side in this feed. The AI Transport SDK is moving fast and pre-1.0 — durable execution in 0.5.0, mid-run steering in 0.6.0, an OpenAI Responses codec in 0.7.0, each roughly ten days apart and each carrying breaking changes. The Pub/Sub and Java SDKs move at a steadier pace, working through LiveObjects reach, React and React Native support, and now connectivity fallbacks.
What is Composio?
Composio runs an aggressive enterprise-hardening pass — Webhook Triggers V2, auth migration, security primitives.
Composio is in heads-down platform-hardening mode. Webhook Triggers V2 introduces a first-class webhook_endpoints resource with a dedicated ingress URL per OAuth app. The legacy POST /api/v3/connected_accounts path is being retired for managed OAuth connections (with a phased migration window in May–July 2026). The proxy execute endpoint now enforces same-domain outbound URLs to prevent Authorization-header leakage. SDKs added a workbench sandbox compute tier picker, multi-connection guard parity in link(), and several breaking removals around legacy file-handling flags.
Ably vs Composio: editorial side-by-side
Ably
6.3INFRA · APIS
Ably is building an agent transport layer on its realtime core, shipping AI SDK versions every ten days.
◆ Current state
Two release trains run side by side in this feed. The AI Transport SDK is moving fast and pre-1.0 — durable execution in 0.5.0, mid-run steering in 0.6.0, an OpenAI Responses codec in 0.7.0, each roughly ten days apart and each carrying breaking changes. The Pub/Sub and Java SDKs move at a steadier pace, working through LiveObjects reach, React and React Native support, and now connectivity fallbacks.
◆ Where it's heading
Ably is treating agent conversations as a transport problem — sessions, resumability, and multi-client reconciliation — rather than as a model-integration problem, and the primitives shipping in AI Transport keep pointing that way. The Pub/Sub line is being pulled along behind it: LiveObjects path APIs and React hooks are the state layer those agent sessions need. The pre-1.0 SDK will keep breaking as the shape settles, which is a reasonable trade while the category is unsettled.
◆ Prediction
Expect AI Transport to keep adding provider codecs beyond OpenAI Responses and to approach an API freeze as breaking changes get more expensive. LiveObjects support should continue spreading across the language SDKs, following the Java path-based API with other platforms.
Composio
6.3INFRA · APIS
Composio runs an aggressive enterprise-hardening pass — Webhook Triggers V2, auth migration, security primitives.
◆ Current state
Composio is in heads-down platform-hardening mode. Webhook Triggers V2 introduces a first-class webhook_endpoints resource with a dedicated ingress URL per OAuth app. The legacy POST /api/v3/connected_accounts path is being retired for managed OAuth connections (with a phased migration window in May–July 2026). The proxy execute endpoint now enforces same-domain outbound URLs to prevent Authorization-header leakage. SDKs added a workbench sandbox compute tier picker, multi-connection guard parity in link(), and several breaking removals around legacy file-handling flags.
◆ Where it's heading
The arc is unmistakable: Composio is converting its rapidly built integration plane into something defensible to ship to enterprise customers. Auth migrations, credential redaction, file-upload hardening, same-domain proxy enforcement, observability APIs, and dedicated webhook ingress per OAuth app are all moving in lockstep. Cadence is high (most releases land in clusters on the same day) and tightly coupled — backend, SDKs, and migration plans ship together.
◆ Prediction
Expect the migration windows to drive a wave of customer-facing breaking-change communications, and observability APIs to keep maturing toward billing-grade usage metering. SOC 2 / SOC 3 or related compliance positioning is the natural follow-on once the security primitives stabilize.
