Why do my WebAssembly modules go dark the moment they enter production?
Opportunity
WASM is now a real deployment target at the edge, in serverless, and in plugin sandboxes. Container workloads have had OpenTelemetry, Prometheus, and structured logging for years; WASM workloads running under WASIp3 hosts do not emit guest-level spans by default and require deliberate instrumentation wiring that most frameworks omit. Stack traces in production failures reduce to binary addresses because DWARF debug info is stripped at build time and source maps do not survive most deployment pipelines. Operators cannot set up the same alerting and dashboards they use for containers because there is no standard way to get telemetry out of a running WASM module without modifying the guest code itself.
Why it matters
Without native production observability, WASM cannot displace containers in any workload where on-call engineers need to diagnose a live incident.
How I score the opportunity
The Opportunity Score is my own read, not a measurement: how much it hurts, how often it bites, and how little exists to solve it today. Higher means I think it is more worth building.
How much pain it causes when it shows up.
How often people actually run into it.
How little good tooling exists for it today.
More problems worth solving
Why is the software we depend on most the worst to use?
TechWhy do I still own none of the data I generate?
TechWhy can I not get a receipt proving my data was actually deleted?
TechWhy can I not know if what is running matches what my SBOM declared?
TechWhy does every C2PA provenance chain break the moment content hits social media?
TechWhy do my AI-generated tests pass on the bugs they were meant to catch?
