Rivet is repositioning its actor platform as the cheap runtime layer for coding agents.
Rivet is shipping at a high cadence and pivoting its narrative toward AI-agent infrastructure. The recent window includes agentOS v0.2 (a WebAssembly-powered, low-cost alternative to sandboxes for running coding agents), Rivet Compute (serverless hosting for actors), a Rust rewrite of Secure Exec, and new Rust and Effect SDKs for Rivet Actors. The pitch is that agents need a lightweight Linux VM, not a heavy sandbox.
Kinde broadens its auth surface to passkeys while building out billing and B2B controls.
Kinde is shipping monthly feature roundups that consistently advance three fronts: authentication breadth, self-serve billing, and enterprise/B2B controls. The latest release adds passkeys (WebAuthn/FIDO2) for passwordless sign-in, the clearest capability jump in the window. Recent months also brought WhatsApp verification, IdP-initiated SAML, invite controls, and an MCP server for AI agents — a developer-focused auth platform widening on every axis.

The pitch is that agents need a lightweight Linux VM, not a heavy sandbox.
Rivet is layering an agent-runtime stack on top of its actor/edge-compute core: agentOS provides isolated, fast-booting environments for coding agents at a fraction of sandbox cost, Rivet Compute removes infra management, and the multiplying SDKs (Rust, Effect, earlier SQLite) widen language and framework reach. The strategic bet is to become the default execution substrate for coding agents by undercutting incumbent sandboxes on cost and cold-start.
Expect agentOS to keep hardening (more language runtimes, orchestration features) and Rivet to push the cost-versus-sandbox comparison as its primary wedge, likely with managed-platform and pricing milestones next.

Kinde is racing to close the feature gap with incumbent auth providers while differentiating on developer experience and built-in monetization. Authentication is going passwordless and omni-channel (passkeys, WhatsApp, SAML), billing is becoming a first-class self-serve product, and the MCP server stakes an early claim on auth for AI agents. The direction is a single platform that handles identity and billing together.
Expect continued enterprise hardening — likely deeper SSO/SCIM and organization-level controls — paired with more billing automation, as Kinde pushes up-market into B2B.
