Stytch
Now inside Twilio, Stytch's independent cadence has slowed to a trickle.
A side-by-side editorial comparison of ElevenLabs and Retool — release velocity, themes, recent moves, and the top alternatives to consider.
ElevenLabs is turning voice agents into versioned, multi-model infrastructure.
ElevenLabs is building two layers at once: a flagship model line (Music v2, Speech Engine) and the developer plumbing around agents, including branch merge/rebase previews, version metadata, and new telephony providers. The changelog reads like a platform maturing past single-call TTS into managed agent infrastructure. Scheduled deprecations of v1 TTS and Scribe models signal a deliberate cleanup of the older surface.
Retool bends its app builder toward AI and external deployment atop the 4.0 self-hosted base
Retool is shipping on two fronts at once: stabilizing the self-hosted 4.0 line (RBAC database migration, stable patches, upgrade FAQs) and steadily modernizing the new app builder. Recent releases add production-grade controls like custom domains and customizable Content Security Policy, alongside AI-adjacent workflow features such as restoring app state from the Chat tab. The classic-to-new-builder migration path keeps widening, now covering custom components and organization-level themes.

Scheduled deprecations of v1 TTS and Scribe models signal a deliberate cleanup of the older surface.
The direction is agents-as-software: branches, rebases, previews, and version parents borrow Git's model for managing agent configuration, while telephony (Exotel alongside Twilio and SIP) and Speech Engine widen where that voice runs. Model releases and lifecycle removals are being run on a schedule. Expect the agent-versioning surface and provider integrations to keep expanding.
Next likely: broader availability of Speech Engine, more telephony and provider integrations, and completion of the July 9 removal of v1 TTS and Scribe models that pushes users onto v2.

The classic-to-new-builder migration path keeps widening, now covering custom components and organization-level themes.
The direction is a Retool that treats internally-built apps as deployable products rather than internal-only tools, with custom domains and CSP controls pointing at externally-facing use. In parallel the platform is absorbing agentic building through MCP app import and chat-driven edits and restores, and metering AI usage via credit packs. The self-hosted 4.0 groundwork suggests enterprise governance is the near-term priority.
Expect the classic-app conversion path to keep closing gaps until the old builder is deprecated, and for the 4.0 RBAC plumbing to surface as a user-facing permissions layer. AI-driven building looks set to deepen rather than plateau.
