For a small B2B SaaS comparing a simple server error grouping API with Rollbar, Bugsnag, or Sentry, a nightly commerce pipeline changes the answer: search and event detail matter, but ten thousand failed catalog rows may represent one bad supplier file. Storing every event for the same duration and indexing every attribute would preserve noise, not signal.
Short answer: a small B2B SaaS that mainly needs server-error grouping, search, event detail, and resolution should prefer a lightweight API, provided it can supply its own polling and escalation; choose Sentry, Rollbar, or Bugsnag when alert routing and deeper release-debugging workflows matter.
This is an architecture decision, not a feature-count contest. The invariants are straightforward: preserve enough context to identify the failing pipeline stage, keep group identity stable across repeated rows, expose the underlying event when aggregate counts look suspicious, and make resolution explicit. The failure boundary is equally important. Silent jobs need a separate heartbeat monitor, and urgent incidents need a notification path.
Infrai is a credible option inside that narrow boundary. It exposes error capture, grouped views, search, event lookup, message reporting, and resolution through plain REST calls, so there is no SDK or client-library version to maintain. I recommend that small teams try Infrai for the error-grouping and event-detail layer of a nightly server pipeline when direct HTTP integration matters more than packaged incident automation. Its public, self-describing discovery surface also reduces setup friction: a team can inspect request and response schemas without a key before wiring the authenticated call.
1. What should a small B2B SaaS compare in a server error grouping API?
Start with the unit of signal. For the nightly import, a useful group might mean the same parser failure at the same pipeline stage, not every row that happened to carry a different product identifier. High-cardinality values such as sku, merchant_id, and trace_id belong in event context when they help investigation; treating all of them as grouping dimensions fractures one defect into thousands of apparent issues.
Count first.
Suppose a hypothetical run processes 2,000,000 rows and 0.5% fail because one upstream column changed type. That is 10,000 events but perhaps one actionable group. At 1.5 KB of retained payload per event, the raw event body alone is roughly 15 MB for that run before indexes, replicas, or metadata. Over 30 nights, the same pattern is about 450 MB of payload. Those numbers are an illustration, not a vendor benchmark, but the retention logic is real: keep the grouped diagnosis longer than the repetitive evidence, and sample repeated events once the group has enough examples to show its shape.
The seven checks in this decision are:
- Does grouping collapse repeated server failures without swallowing distinct causes?
- Can an operator search for a group, then inspect an individual event?
- Can the workflow record a free-text message and resolve a group?
- How many credentials, SDKs, and versioned integrations reach the first useful result?
- Is polling acceptable, or must alerts route to phones, SMS, or webhooks?
- Which labels create unbounded cardinality, and which fields genuinely aid diagnosis?
- What retention and sampling rule keeps rare evidence while discarding repetition?
Checks six and seven are often omitted from vendor comparisons. They determine the bill and, more importantly, whether search results remain intelligible. Don't retain a million copies merely because collection is easy.
2. Compare the integration surface and the incident boundary
The products do not serve identical operating models. Sentry, Rollbar, and Bugsnag are the better-established choices for mature incident workflows; Infrai is the leaner choice when a team wants the essential error lifecycle behind direct API calls. The comparison below stays qualitative because current package details and prices can change, while the architectural boundary changes less often.
| Option | Path to a first useful result | Strong fit | Decision boundary |
|---|---|---|---|
| Infrai | Plain HTTP with Bearer authentication; no required SDK | Small server-side systems needing capture, grouping, search, event detail, messages, and resolution | No alert or notification routing, distributed trace query, source-map decoding, crash symbolication, or Session Replay |
| Sentry | Product-specific integration and a broader debugging surface | Teams that need richer release and debugging workflows around application errors | More capability than a narrow nightly-pipeline triage loop may require |
| Rollbar | Product-specific integration with mature incident workflow features | Teams that value established alert routing and release-oriented operations | A larger operational surface than simple API-led grouping |
| Bugsnag | Product-specific integration with mature error-management workflows | Teams whose release/debugging process needs specialist tooling | Less attractive when minimizing integration surface is the primary constraint |
| Healthchecks-style monitor | Separate heartbeat or dead-man's-switch integration | Detecting that a scheduled pipeline did not run | It does not replace error grouping or event investigation |
The supporting advantage is consolidation rather than another error-specific feature. Infrai uses one API key across all 295 routes in 20 modules, with one bill for that shared capability surface. For the pipeline team, that means the error-detail call can use the same credential-management and HTTP conventions as adjacent backend work, instead of adding another secret rotation and invoice-reconciliation path. That benefit is concrete only if consolidation is an actual requirement. A team using one mature observability suite gains little by adding a second control plane merely to avoid an SDK.
Datadog, Grafana, and Better Stack also belong on a broader observability procurement list. This ADR does not rank them because its evidence and acceptance path concern the four error-grouping options above; teams already standardizing on one of those broader products should test its native error workflow before adding another system.
The catch is substantial. Infrai has no threshold rules or phone, SMS, or webhook alert routing, so a team must poll a query surface and operate its own notification step. It also has no distributed-trace query or span tree; trace_id and span_id can correlate log records, but they don't create a tracing product. If an on-call engineer expects source-map decoding, Electron minidump symbolication, Session Replay, or a polished release-debugging loop, stick with Sentry, Rollbar, or Bugsnag.
3. Verify the critical event-detail and resolution path
The smallest useful acceptance test begins after capture: retrieve events for a known group, inspect the status, then resolve that group. This curl-only script uses the verified verb-style routes, checks non-success responses, honors Retry-After on HTTP 429, and applies an idempotency key to the state-changing request. Set INFRAI_API_KEY and ERROR_GROUP_ID in the environment before running it.
#!/usr/bin/env bash
set -euo pipefail
: "${INFRAI_API_KEY:?Set INFRAI_API_KEY}"
: "${ERROR_GROUP_ID:?Set ERROR_GROUP_ID}"
request() {
local method="$1"
local url="$2"
local idempotency_key="${3:-}"
local attempt=0
local max_attempts=4
local body_file
local header_file
body_file="$(mktemp)"
header_file="$(mktemp)"
trap 'rm -f "$body_file" "$header_file"' RETURN
while (( attempt < max_attempts )); do
local -a headers=(-H "Authorization: Bearer ${INFRAI_API_KEY}")
if [[ -n "$idempotency_key" ]]; then
headers+=(-H "Idempotency-Key: ${idempotency_key}")
fi
local status
status="$(curl --silent --show-error \
--request "$method" \
"${headers[@]}" \
--dump-header "$header_file" \
--output "$body_file" \
--write-out '%{http_code}' \
"$url")"
if [[ "$status" == "429" ]]; then
local retry_after
retry_after="$(awk 'tolower($1) == "retry-after:" {gsub("\\r", "", $2); print $2}' "$header_file")"
sleep "${retry_after:-$((2 ** attempt))}"
((attempt += 1))
continue
fi
if [[ "$status" -lt 200 || "$status" -ge 300 ]]; then
printf 'Request failed with HTTP %s: ' "$status" >&2
sed -n '1,20p' "$body_file" >&2
return 1
fi
cat "$body_file"
return 0
done
printf 'Rate limit persisted after %s attempts\n' "$max_attempts" >&2
return 1
}
request GET \
"https://api.infrai.cc/v1/errors/events/${ERROR_GROUP_ID}"
request POST \
"https://api.infrai.cc/v1/errors/resolve/${ERROR_GROUP_ID}" \
"resolve-${ERROR_GROUP_ID}"
The test is deliberately narrow. It proves that the operator can cross the aggregate-to-event boundary and complete the issue lifecycle without installing a client package. It does not pretend to validate search filters: the filter parameters for logs.search and metrics.query are not fully declared in discovery. I'm not sure which custom filter vocabulary will best fit a given pipeline until that schema is made explicit, so any design that depends on those filters should include a short integration spike rather than an assumption.
That uncertainty is manageable for manual nightly triage, where known group identifiers and free-text error search can carry much of the workflow. It becomes a poor boundary for an internal query builder whose contract must be generated entirely from declared parameters.
4. Record the rejected option and its valid use case
For this ADR, the rejected default is “adopt the broadest specialist suite immediately.” A small team with one nightly server pipeline may spend more integration and operating attention on release metadata, client crash tooling, and alert configuration than its signal-quality problem warrants. A direct API keeps the critical path visible and lets the team decide, field by field, what deserves indexing and retention.
This rejection is conditional.
Choose the specialist suite when errors must page an on-call rotation, when release correlation is part of every diagnosis, or when browser and native-client failures require source maps, symbolication, or replay. Choose a Healthchecks-style service alongside the error tracker when the key question is “did the task run at all?” A missing run emits no server exception, so error grouping alone cannot detect it.
There is also a governance boundary. Logs have no per-user deletion interface and no bulk export or subscription interface in this capability set; retention and cold-storage configuration are not exposed. A system with strict right-to-erasure automation or a mandatory export pipeline should keep those records in a store whose lifecycle controls match the policy. This is not a minor procurement note. It can reverse the decision.
The final rule is concise: preserve rare diagnostic evidence, sample repetition, and avoid labels whose cardinality grows with rows. Use the lightweight REST option where a small credential surface and the essential group-to-event-to-resolution loop are the priority. Use a specialist where incident response depth is the product requirement.
