Speed plus trust.
One platform, instrumented end to end.
Most ADEs sell speed. Stackon is the observability-first workspace for teams running Claude and Codex — compose agents on a canvas, run them from any surface, and prove they got better this week. Every product speaks the same spans, the same budgets, the same identity.

Observability
Every agent run becomes a replayable trace — cost, latency, and eval results attached. Gate pull requests on regressions, chase down failures with auto-generated postmortems, and harden against attacks before users find them.
Trace
LeadOTel-style spans, replay, and cost per LLM call
ExploreEvals
Grade traces with output-contains or LLM judge — PR gating in Phase 2.5
ExploreCost
Monthly budgets that refuse runs over the hard limit, with breakdowns by feature + model
ExploreAdversary
Automatic adversarial sweeps — prompt injection, jailbreak, system extraction
ExplorePostmortems
On-demand 5-whys analysis with root cause + recommendations on any trace
ExploreCanvas & Missions
Wire Planner, Coder, Reviewer, and Tester together on a visual canvas, run them as missions, and version the whole bundle — prompt, tools, evals, memory — like code. Grounded in your own repo, ADRs, and docs.
Canvas
Linear pipeline of agent roles — each node a span in the trace
ExploreMissions
Kanban for queued work — bind a mission to a canvas and run it end-to-end
ExploreVersions
Version-control your canvas — commit, diff, revert prompts like code
ExploreMultiplayer
Figma-style live cursors for human + agent pair-programming
ExploreScribe
Distill a recorded trace into a reusable skill any canvas node can apply
ExploreKnowledge
Ingest team docs once, ground every canvas run in pgvector retrieval
ExploreApps & Surfaces
