A side-by-side editorial comparison of Auth0 and PlanetScale — release velocity, themes, recent moves, and the top alternatives to consider.
Auth0 vs PlanetScale: at a glance
What is Auth0?
Auth0 hands tenants a throttle on their own noisy apps
Custom Rate Limits enter Early Access, letting a tenant cap requests per second for individual clients or whole classes of them — third-party, CIMD — so one application cannot exhaust the tenant's Authentication API rate limit entitlement. Policies are configured through an API and can be rolled out in notify-only mode before they start blocking. It arrives in a dense window that also brought Flexible Password Policy to GA and Custom Prompts parity across social and enterprise connections.
What is PlanetScale?
PlanetScale is building out Postgres while making every control reachable without the dashboard.
The Postgres line carries the new capability: vectorscale extension support, storage configurable at database creation, out-of-memory alerts by both email and webhook, a customisable log line prefix, a Discovery Tool for evaluating existing databases, and updated pricing for private connection traffic. Database Traffic Control introduced resource budgets and has since gained warning thresholds and CLI management. The surface work is constant — API endpoints for backup policies, maintenance schedules, schema recommendations, deploy-request storage checks and invoice status, a Terraform provider at v1, and an Insights-only MCP server.

Auth0 hands tenants a throttle on their own noisy apps
◆ Current state
Custom Rate Limits enter Early Access, letting a tenant cap requests per second for individual clients or whole classes of them — third-party, CIMD — so one application cannot exhaust the tenant's Authentication API rate limit entitlement. Policies are configured through an API and can be rolled out in notify-only mode before they start blocking. It arrives in a dense window that also brought Flexible Password Policy to GA and Custom Prompts parity across social and enterprise connections.
◆ Where it's heading
Two threads dominate. One is agent and delegation infrastructure — Agents as Principal, Token Vault Privileged Worker, Custom Token Exchange session delegation — all still in Early Access. The other is tenant self-service: rate limits, blocklists, organization search and roles, global search. Auth0 is systematically converting things that required support intervention into API-configurable policy.
◆ Prediction
The Early Access items now stacking up, particularly the agent-identity pieces, are the obvious GA candidates next, following the Flexible Password Policy path from Early Access to general availability.
PlanetScale

PlanetScale is building out Postgres while making every control reachable without the dashboard.
◆ Current state
The Postgres line carries the new capability: vectorscale extension support, storage configurable at database creation, out-of-memory alerts by both email and webhook, a customisable log line prefix, a Discovery Tool for evaluating existing databases, and updated pricing for private connection traffic. Database Traffic Control introduced resource budgets and has since gained warning thresholds and CLI management. The surface work is constant — API endpoints for backup policies, maintenance schedules, schema recommendations, deploy-request storage checks and invoice status, a Terraform provider at v1, and an Insights-only MCP server.
◆ Where it's heading
PlanetScale is doing two things at once: closing the gap between its Postgres offering and its MySQL heritage, and making every operation scriptable. The API, Terraform and MCP work share a single goal — nothing should require the dashboard — and the schema-recommendations feature landing simultaneously as a REST endpoint and an MCP tool is the clearest statement of it. Traffic Control is the exception, launched as a named product surface and then immediately given the same CLI and threshold treatment.
◆ Prediction
Expect the remaining Postgres parity items and more MCP tools mirroring existing REST endpoints, following the schema-recommendations pattern where both arrived together.
