AppSignal vs DNSimple
A side-by-side editorial comparison of AppSignal and DNSimple — release velocity, themes, recent moves, and the top alternatives to consider.
AppSignal vs DNSimple: at a glance
What is AppSignal?
AppSignal links incidents from GitHub and gives its MCP server cleaner metric series.
AppSignal spent late October on tracing: the service map left its feature flag, traces link to host metrics and deploys, and cross-app services show by name. November adds two connection points: pasting an incident URL into a GitHub issue or PR now links it back to the incident, and the AppSignal MCP returns metric time series in a format AI agents read more accurately. A batch of fixes for deploy, host and pod pages rounds it out.
What is DNSimple?
DNSimple's origin name servers answer a quarter faster at p90 after erldns work
DNSimple keeps tuning the Erlang stack it now runs end to end. The November 4 post says p90 query time on its origin name servers is down about a quarter, and about a third for DNSSEC queries, with roughly a third less CPU, and record changes now switch in one step so existing records never briefly disappear. It follows October's dns_erlang rewrite, which cut CPU per query by 12%, and the August finish of the migration to fully owned infrastructure. Above that layer sit the CLI launched in May, browser login from June, and Domain Trustee.

AppSignal links incidents from GitHub and gives its MCP server cleaner metric series.
◆ Current state
AppSignal spent late October on tracing: the service map left its feature flag, traces link to host metrics and deploys, and cross-app services show by name. November adds two connection points: pasting an incident URL into a GitHub issue or PR now links it back to the incident, and the AppSignal MCP returns metric time series in a format AI agents read more accurately. A batch of fixes for deploy, host and pod pages rounds it out.
◆ Where it's heading
The product is stitching its views together and exposing them to the tools developers already use, GitHub on one side and AI agents via MCP on the other. Each release removes a step between seeing a problem and acting on it.
◆ Prediction
Expect more MCP tools or outputs aimed at agents, such as trace or incident data, following the metric series change.
DNSimple

DNSimple's origin name servers answer a quarter faster at p90 after erldns work
◆ Current state
DNSimple keeps tuning the Erlang stack it now runs end to end. The November 4 post says p90 query time on its origin name servers is down about a quarter, and about a third for DNSSEC queries, with roughly a third less CPU, and record changes now switch in one step so existing records never briefly disappear.

Above that layer sit the CLI launched in May, browser login from June, and Domain Trustee.
◆ Where it's heading
Since owning its full DNS edge, DNSimple has turned to measurable performance work on erldns and dns_erlang, published openly. The product layer above, CLI and API clients, is moving more slowly.
◆ Prediction
Expect more erldns and dns_erlang performance posts; the entries show no sign of a new customer-facing product soon.
