Features

Everything an engineering team needs.
Nothing it doesn't.

Six pillars, built around the assumption that the people instrumenting your product are also the ones building it.

Schema-as-code

Events live in your repo.

Define every event in TypeScript, Python, or Go. The Throughline CLI validates on every commit, and a missing or renamed property fails the PR before it ever ships. Dashboards stay accurate because they can't fall behind.

· Generates typed SDKs for 9 languages
· GitHub & GitLab integrations included
· Migrate events with versioned schemas
· Lint rules for naming conventions

Open SQL

Every chart is a query you can read.

Throughline ships a real SQL editor. Every dashboard tile is a query — readable, forkable, and connectable to your existing warehouse. No proprietary query language to learn, no DSL purgatory.

· DuckDB-compatible dialect
· One-click pipe to Snowflake / BigQuery / Redshift
· Saved queries with role-based access
· Notebook mode for ad-hoc analysis

Replay

Trace a user across every service.

Pivot from a chart to the underlying session, then watch every event the user fired across your microservices — front-end clicks, API calls, async jobs — in order, on a single timeline. The same engine powers production alerting.

· Cross-service correlation IDs
· Sub-millisecond timeline scrubbing
· Optional session replay (privacy-redacted)
· Bookmark + share with one URL

And the rest of the table stakes.

Funnels & cohorts

First-class. Forkable. Built on the same SQL layer as the rest of the app.

Feature flags

Optional. Native A/B integration with statistical sig built in. No second tool to buy.

Privacy by default

PII tags are redacted before they hit storage. EU and US data residency. No "we tried our best" anti-patterns.

Self-host or cloud

Same Docker image, same SDKs. Self-host customers get parity within 7 days of a new release.

CLI & terraform

Everything in the UI has a CLI verb. Workspaces, users, alerts — all infrastructure-as-code.

Alerts & on-call

Anomaly detection on any saved query. PagerDuty, Slack, Opsgenie. Statefully de-duped.
