incident.io vs Stacker: at a glance
What is incident.io?
Alert rate limits stop being per-source and start being per-tenant, by query.
Investigations went generally available on 5 August, with Nexus posting a root-cause hypothesis and its evidence into the incident channel minutes after declaration. The releases since have been the operational surround: a 24/7 schedule coverage policy that flags gaps before a rotation goes unstaffed, more filtering in Insights, agent-written status page updates, and a resource-by-resource Terraform provider rework. This release lets an alert source extract a value from the incoming payload with a query expression and shard its rate limit on that value, so one noisy customer or cluster no longer consumes the whole source's budget.
What is Stacker?
Stacker's AI agent has absorbed every part of app building except the data itself.
Stacker builds internal tools and customer portals on top of existing data. From late October 2025 the entire changelog is one project: an AI Builder Agent that generates and edits apps by conversation. In under seven weeks it went from generating initial pages and layouts to editing tables and fields, creating lookups, rollups and formulas, reshaping create forms, reordering navigation, building white-labelled external portals with custom domains and permissions, and finally taking a spreadsheet upload and configuring a schema and matching layouts from it.

◆ Current state
Investigations went generally available on 5 August, with Nexus posting a root-cause hypothesis and its evidence into the incident channel minutes after declaration. The releases since have been the operational surround: a 24/7 schedule coverage policy that flags gaps before a rotation goes unstaffed, more filtering in Insights, agent-written status page updates, and a resource-by-resource Terraform provider rework. This release lets an alert source extract a value from the incoming payload with a query expression and shard its rate limit on that value, so one noisy customer or cluster no longer consumes the whole source's budget.
◆ Where it's heading
Two threads run in parallel. Nexus started inside the incident channel doing diagnosis and has moved outward to the customer-facing artifact. The second is platform work for customers running at scale — coverage policies, escalation routing, and now rate limiting that understands the shape of the payload rather than treating a source as one undifferentiated stream. Sharded limits are what you build when a single alert source fronts many tenants, which says something about the size of the deployments driving the roadmap.
◆ Prediction
Rate limits that read a query expression out of the payload share machinery with routing and deduplication, so the same expression surfacing in alert routing rules is the likely next step. The changelog entry does not say.
Stacker
0.0INFRA · APIS
Stacker's AI agent has absorbed every part of app building except the data itself.
◆ Current state
Stacker builds internal tools and customer portals on top of existing data. From late October 2025 the entire changelog is one project: an AI Builder Agent that generates and edits apps by conversation. In under seven weeks it went from generating initial pages and layouts to editing tables and fields, creating lookups, rollups and formulas, reshaping create forms, reordering navigation, building white-labelled external portals with custom domains and permissions, and finally taking a spreadsheet upload and configuring a schema and matching layouts from it.
◆ Where it's heading
The sequencing is deliberate: each release hands the agent one more thing that previously required the no-code editor, while the company repeatedly reassures users that the full editor still works on AI-built apps. That dual framing — build by conversation, refine by hand — is the position Stacker is defending, and it is a reasonable answer to pure prompt-to-app tools that leave nothing to adjust afterwards. The portal release is the notable widening, since it points the agent at the external-user product rather than internal tools.
◆ Prediction
Every surface except data connection has now been handed to the agent; connecting and mapping an external source — the step still done manually before any of this works — is the remaining gap, and the spreadsheet uploader is the first move toward closing it.
