What is Headscale?

Headscale stops approximating Tailscale's control plane and starts matching it on purpose.

Headscale's visible work is a single long beta line, 0.29.0-beta.1 through beta.4, spread from late May to mid-June. The release notes are cumulative and identical across all four betas, describing a rebuilt ACL packet-filter implementation validated against real Tailscale clients and the official SaaS, plus support for SSH rules using the check action with OIDC or CLI approval. Minimum supported Tailscale client is pinned at v1.80.0.

What is ToolJet?

ToolJet bundles MCP, multi-LLM switching, and PATs in a single beta — shifting from app builder to AI development platform

ToolJet v3.21.71-beta landed the platform's most consequential feature batch in recent memory: Personal Access Tokens, two-factor authentication, LLM provider switching with AI query transformation, MCP authentication via PATs, OneNote integration, CSV import into ToolJet DB, multi-model build support with a redesigned model picker, OTel observability on semantic conventions, and an AI-powered content generation option. The LTS branch ships more conservatively, receiving MCP bundling in the EE image and AI build cancellation support.

Headscale stops approximating Tailscale's control plane and starts matching it on purpose.

◆ Current state

Headscale's visible work is a single long beta line, 0.29.0-beta.1 through beta.4, spread from late May to mid-June. The release notes are cumulative and identical across all four betas, describing a rebuilt ACL packet-filter implementation validated against real Tailscale clients and the official SaaS, plus support for SSH rules using the check action with OIDC or CLI approval. Minimum supported Tailscale client is pinned at v1.80.0.

◆ Where it's heading

The project is treating behavioural parity with the hosted service as something to be tested rather than assumed — generating ACL test cases systematically against the SaaS and fixing the differences that surfaced. Adding interactive SSH approval moves headscale past connectivity into access control, which is the harder half of what Tailscale sells. The long beta series without a stable cut suggests the maintainers are unwilling to ship that surface until the packet-filter differences are fully closed.

◆ Prediction

A stable 0.29.0 is the obvious next step once the beta line settles, since the feature set has been frozen across four betas. What remains unclear from these notes is what actually changed between the betas, as each restates the same cumulative text.

ToolJet bundles MCP, multi-LLM switching, and PATs in a single beta — shifting from app builder to AI development platform

◆ Current state

ToolJet v3.21.71-beta landed the platform's most consequential feature batch in recent memory: Personal Access Tokens, two-factor authentication, LLM provider switching with AI query transformation, MCP authentication via PATs, OneNote integration, CSV import into ToolJet DB, multi-model build support with a redesigned model picker, OTel observability on semantic conventions, and an AI-powered content generation option. The LTS branch ships more conservatively, receiving MCP bundling in the EE image and AI build cancellation support.

◆ Where it's heading

ToolJet is repositioning from a low-code internal tool builder to an AI-native development platform. The MCP integration and multi-LLM provider switching indicate they're building for a world where AI agents are first-class citizens in app logic. The PAT + MCP combination creates a developer-facing API surface that third-party tools can call against ToolJet-managed apps, which is a meaningfully different product direction.

◆ Prediction

The beta's LLM-switching and MCP foundation will likely surface as a differentiated 'AI workflows' tier in a future pricing change, separating standard app-building from agentic AI features that consume LLM credits.
