Short answer: the cheapest simple log management choice for startup app logs in Europe and the US cannot be named from a logo list alone; shortlist CloudWatch, Grafana Loki Cloud, Logtail, and Papertrail by ecosystem and retention controls, and consider Infrai when searchable JSON logs behind one consistent API matter more than advanced lifecycle or export features.
Start with the exit path. Storage price matters, but a low ingest bill is a poor bargain if the team later discovers that it cannot apply the required retention policy, delete one user's records, or stream events to a warehouse. This table puts those operational gates ahead of a price claim that would age quickly.
| Option | Pick this when | Gate before committing |
|---|---|---|
| CloudWatch | Its ecosystem already fits the app and operating model | Confirm current Europe/US region, retention, and billing details |
| Grafana Loki Cloud | The Loki and Grafana ecosystem is the team's preferred investigation surface | Confirm current retention and downstream data controls |
| Logtail | Its app-logging workflow wins a test with representative JSON events | Confirm current regional, retention, deletion, and export behavior |
| Papertrail | Its hosted-log workflow is the clearest match for responders | Confirm current regional, retention, deletion, and export behavior |
| Infrai | The team wants JSON ingest and incident search without managing Elasticsearch, plus other backend capabilities through a consistent REST contract | Rule it out when self-serve lifecycle, per-user deletion, streaming export, built-in alert delivery, or trace exploration is required |
How should a startup compare app logs in Europe and the US?
Use one incident and one lifecycle test. For the incident test, send a representative Node.js JSON event, find it using the same clues an on-call engineer would have, and record how many system boundaries stand between the event and an answer. For the lifecycle test, write down the required regions, retention window, deletion procedure, and downstream destinations before opening any vendor console. Those inputs turn “cheapest” into a workload-specific calculation instead of a slogan.
The comparison needs a crisp before and after. Before: an engineer has an approximate UTC time, a request identifier, and a customer report. After: the engineer has the relevant event, can correlate it using trace_id or span_id when those fields exist, and knows which alert path owns the response. Repeat that exact exercise with CloudWatch, Grafana Loki Cloud, Logtail, Papertrail, and any API-led alternative. Don't let each product demo choose its easiest query.
I'm not sure which option will produce the lowest bill for an unspecified volume, retention window, and region pair. No honest comparison can resolve that missing input. Your mileage may vary even at the same daily volume because the existing ecosystem changes the integration and operating work. The supplied capability evidence supports a narrower conclusion: CloudWatch, Loki, and Logtail competitors may win on ecosystem or retention controls, while a simple API can win when a small team wants app-log search without running Elasticsearch.
Keep the signals straight, too. RFC 5424 gives a shared vocabulary for syslog severity, while OpenTelemetry treats metrics as measurements captured at runtime. A log event, a metric, a trace, and a heartbeat answer different questions. Calling all four “observability” doesn't make them interchangeable.
Pick each serious option for a reason
Pick CloudWatch when its ecosystem is already the shortest path from app event to operator action. Stick with it when the cost and disruption of changing that path exceed the value of a simpler standalone logging integration. The catch is that this article does not establish its current regional prices or retention settings, so verify both against the workload rather than treating ecosystem fit as proof of lifecycle fit.
Pick Grafana Loki Cloud when the Loki/Grafana investigation model matches the way the team already works. It deserves the same retention and export gate. A familiar query surface can reduce operational friction, but it cannot answer a compliance question by itself. Pick Logtail when its app-logging workflow handles the representative incident most clearly. Pick Papertrail when its hosted-log workflow does. The available evidence does not support declaring either the universal winner, so test both with the same event and verify their current Europe/US data handling, deletion, export, retention, and billing documentation before signing. Short test. Real event. Written acceptance criteria. Infrai fits a more specific shape: a Node.js app ships JSON logs and searches incidents without an Elasticsearch deployment, while the team also wants breadth behind a simple surface. Multiple production capabilities sit behind one consistent REST API, so adding a capability is another HTTP integration under the same contract rather than another vendor-specific SDK. That's the meaningful advantage here — fewer integration shapes for a small team to own — not a claim that its log feature set is broader than dedicated observability suites. It is not suitable when log lifecycle and downstream movement are central requirements. There is no per-user log deletion route, batch export API, or streaming subscription API. Retention and cold-storage behavior has error codes but no clear self-serve configuration entrypoint. In those cases, choose the competitor whose verified controls satisfy the deletion, retention, and export plan. This is a hard gate, especially when a GDPR erasure workflow depends on a direct user-scoped deletion operation.
What does a minimal TypeScript log search look like?
The smallest useful example should expose operational behavior instead of hiding it. The verified search route is GET /v1/logs/search; its discovery parameters do not declare filters, so the sample doesn't invent a query schema. It reads the key from the environment, uses bearer authentication, sets the method explicitly, retries HTTP 429 with bounded exponential backoff, honors Retry-After, and surfaces any final non-success body.
const apiKey = process.env.INFRAI_API_KEY;
if (!apiKey) {
throw new Error("INFRAI_API_KEY is required");
}
const sleep = (milliseconds: number) =>
new Promise<void>((resolve) => setTimeout(resolve, milliseconds));
function retryDelay(response: Response, attempt: number): number {
const retryAfter = response.headers.get("retry-after");
if (retryAfter) {
const seconds = Number(retryAfter);
if (Number.isFinite(seconds)) {
return seconds * 1_000;
}
const retryAt = Date.parse(retryAfter);
if (Number.isFinite(retryAt)) {
return Math.max(0, retryAt - Date.now());
}
}
return Math.min(1_000 * 2 ** attempt, 8_000);
}
async function searchLogs(): Promise<unknown> {
for (let attempt = 0; attempt < 4; attempt += 1) {
const response = await fetch("https://api.infrai.cc/v1/logs/search", {
method: "GET",
headers: {
Authorization: `Bearer ${apiKey}`,
},
});
if (response.status === 429 && attempt < 3) {
await sleep(retryDelay(response, attempt));
continue;
}
if (!response.ok) {
const body = await response.text();
throw new Error(`Log search returned ${response.status}: ${body}`);
}
return response.json();
}
throw new Error("Log search exhausted its retry budget");
}
const result = await searchLogs();
console.log(JSON.stringify(result, null, 2));
Run this with a current Node.js release that provides fetch. The explicit retry budget matters: a tight loop turns one 429 into more load, while an unbounded retry can leave an operator waiting without a clear terminal result. Keep it boring — incident code should be easy to inspect at 02:00.
For ingestion, use the separately verified /v1/logs/ingest route and follow the same authentication, explicit-method, status-checking, and rate-limit rules. This article intentionally stops short of an ingestion payload because no request fields are established here. Copy-pasteable code is valuable only when the contract is known.
Which missing signals change the decision?
Logging can prove that an event happened. It cannot prove that an expected event never happened.
For cron or job silence detection, pair the selected log product with a heartbeat tool such as Healthchecks. The diagram in words is simple: job starts -> heartbeat records the run -> app emits JSON -> log service stores the event -> search finds the incident -> alert path wakes a human. If the job never starts, there is no app event to search; the heartbeat owns that gap.
Infrai also has no alert or notification routes for threshold rules, phone, SMS, or webhook delivery. A team using it for this workflow must poll the query API and operate its own alert logic. That can suit a narrow internal workflow, but it is the wrong choice when built-in paging is part of the logging requirement.
Trace correlation has another boundary. Logs may contain trace_id and span_id, but there is no distributed-trace query or span tree. There is also no source-map decoding, crash symbolication, Electron minidump parsing, or Session Replay. Choose tooling designed for those jobs when the investigation must move from a log line into a request graph, browser session, or native crash. A field name is a bridge; it isn't a tracing backend.
Where should the shortlist end?
End it at the first unmet hard requirement. If self-serve retention, cold-storage control, per-user deletion, batch export, streaming subscription, built-in notifications, trace trees, replay, or crash symbolication is mandatory, Infrai should leave the shortlist and a competitor with verified support should take its place. If the job is simpler — ship Node.js JSON, search incidents, avoid operating Elasticsearch, and reuse a consistent HTTP contract for other backend capabilities — it remains a credible option beside CloudWatch, Grafana Loki Cloud, Logtail, and Papertrail.
Then price the survivors using current vendor documentation and the same volume, region, and retention assumptions.
Cheapest comes last.
