v2.4
Webhooks are live.
Three views your team will live in: every source as a row, every change as a line, every event as a webhook.
Sources
One row per connection
Name, kind, owner, last sync, state. The row is the source of truth for whether something is working.

History
Every change, attributed
Who changed what, from which tool, and what it was before. Filter by person, field or day; export the range.
Webhooks & API
The same API we use
Signed events, six retries with backoff, a delivery log you can read. Nothing in the plane is out of reach of the API.
# Any change → your endpoint
POST https://ops.northwind.io/tessel
X-Tessel-Signature: sha256=9f2a…e41c
event: source.delayed · source: stripe · pending: 3
→ 202 Accepted · 41 ms · attempt 1/6
Five things Tessel does that the tab bar doesn’t. Each one is native — no plugins, no scripts, nothing to maintain.
Change history you can read
Every edit, every sync, every retry — with who, what and when. Diffs, not blobs.

Webhooks that just fire
Any change on the plane can hit any endpoint. Signed, retried, logged.
POST /hooks/sync → ops.northwind.io 200
POST /hooks/plan.changed → billing.internal 200
POST /hooks/source.delayed → pager.northwind.io 202
One plane, any source
Issues, docs, billing, repos, CRM, databases. If it has an API, it has a tile.
Search across everything
One box. Results from every source, ranked by what your team touches most.
02
How it works
Four moves
No setup wizard, no migration plan, no six-week rollout. You connect a source and it shows up on the plane, already in sync.
Each move is one thing your team stops doing by hand. Most teams are through all four before lunch on day one.

Twelve tabs
Monday morning, before Tessel. Every tool is a tab, every tab is a login, and nobody knows which one is current.
