What is Kinde?

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.

What is QuestDB?

QuestDB is hardening into the time-series engine for regulated capital markets.

QuestDB's recent feed splits cleanly between shipping and storytelling. On the product side, two solid releases — Enterprise 3.3.1 (Parquet tiering, custom CA, column-level access control) and 9.4.2 (query sharing, new aggregates, a hardening pass) — deepen the database for demanding deployments. On the narrative side, a run of engineering deep-dives and capital-markets case studies (One Trading, Aeron) stakes out finance as the beachhead.

Kinde vs QuestDB: editorial side-by-side

K
Kinde
DEVOPS
3.8

Kinde broadens its auth surface to passkeys while building out billing and B2B controls.

◆ Current state

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.

◆ Where it's heading

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.

◆ Prediction

Expect continued enterprise hardening — likely deeper SSO/SCIM and organization-level controls — paired with more billing automation, as Kinde pushes up-market into B2B.

Q
QuestDB
DEVOPS
5.0

QuestDB is hardening into the time-series engine for regulated capital markets.

◆ Current state

QuestDB's recent feed splits cleanly between shipping and storytelling. On the product side, two solid releases — Enterprise 3.3.1 (Parquet tiering, custom CA, column-level access control) and 9.4.2 (query sharing, new aggregates, a hardening pass) — deepen the database for demanding deployments. On the narrative side, a run of engineering deep-dives and capital-markets case studies (One Trading, Aeron) stakes out finance as the beachhead.

◆ Where it's heading

The direction is rigor over flash: fewer headline features, more of what regulated, high-throughput users need — data tiering, granular permissions, deterministic replay, benchmark honesty. The blog cadence on JIT internals and benchmarking method builds technical credibility, while the case studies name the target customer (24/7 exchanges, real-time surveillance).

◆ Prediction

Expect the next releases to keep filling enterprise gaps — retention/tiering controls and access management — and more finance-sector proof points rather than a new headline capability.
