Your team outgrew laptop k6 runs—but the procurement ticket asks whether to buy **Grafana k6 Cloud** or provision **self-hosted OSS** generators in Kubernetes. Both run the same script format; they differ in who owns uptime, data residency, and the workflow from "edit scenario" to "share report with product."

k6 Cloud vs self-hosted is not a purity debate. It is a **tradeoff matrix**: recurring SaaS cost vs ops labor, hosted collaboration vs git-only artifacts, and whether load generators must live inside a VPC boundary. In this guide you will learn where each option wins, how to run the same script in both models, and which decision table row fits your team—not a generic "cloud is always easier."

## Why the choice affects workflow—not just billing

Teams often compare line-item pricing and ignore execution friction:

- **Generator scaling:** Cloud spins distributed load globally; self-hosted means you size K8s jobs or VM pools ([geo-distributed load testing](/en/blog/geo-distributed-load-testing)).
- **Data residency:** PCI, HIPAA, or customer contracts may forbid sending URLs, tokens, or payloads to SaaS—even if "only metrics" leave the VPC.
- **Collaboration:** Cloud dashboards share runs by link; OSS relies on exported JSON, Grafana, or desktop reports.
- **Maintenance:** Self-hosted patches k6 versions, Chromium for browser tests, and outbound firewall rules yourself.
- **CI integration:** Both support pipeline runs; Cloud adds hosted orchestration, OSS uses your runners ([load testing in CI/CD](/en/blog/load-testing-in-ci-cd)).

Think of Cloud as hiring a load-test control plane; self-hosted as owning the fleet but keeping every byte on your network.

**k6 OSS** runs anywhere you provision CPUs ([getting started](https://k6.io/docs/get-started/running-k6/)). **Grafana k6 Cloud** adds hosted orchestration and dashboards ([Cloud docs](https://k6.io/docs/cloud/)).

## Practical k6 implementation: portable script, two run targets

Write scripts that use **env vars for secrets and base URLs** so the same file runs locally, in CI, against Cloud, or on self-hosted agents—no fork per platform.

**Example script (illustrative—not a production-ready test).** Identical for Cloud upload or `k6 run` on your cluster.

**What this example demonstrates:**

- **Env-driven target:** `API_BASE` switches staging vs Cloud tunnel without script edits.
- **Moderate distributed-friendly rate:** `constant-arrival-rate` splits cleanly across Cloud zones or K8s replicas.
- **Tags for platform comparison:** `run_target:cloud|selfhosted` via `--tag` at invoke time.
- **Thresholds portable:** same SLO gates whether results land in Cloud UI or InfluxDB.

```javascript
import http from 'k6/http';
import { check, sleep } from 'k6';

const BASE = __ENV.API_BASE || 'https://staging.example.com';
const TARGET = __ENV.RUN_TARGET || 'local';

export const options = {
  scenarios: {
    portable_load: {
      executor: 'constant-arrival-rate',
      rate: Number(__ENV.RPS || 50),
      timeUnit: '1s',
      duration: '10m',
      preAllocatedVUs: 20,
      maxVUs: 200,
      tags: { run_target: TARGET, suite: 'cloud-vs-oss' },
    },
  },
  thresholds: {
    http_req_failed: ['rate<0.01'],
    'http_req_duration{run_target:' + TARGET + '}': ['p(95)<700'],
  },
};

export default function () {
  const res = http.get(`${BASE}/v1/catalog`, {
    headers: { Authorization: `Bearer ${__ENV.TOKEN}` },
    tags: { route: 'catalog', run_target: TARGET },
  });
  check(res, { 'catalog 2xx': (r) => r.status >= 200 && r.status < 300 });
  sleep(0.2);
}
```

**Patterns that work**

- **Pilot both:** same script, one Cloud trial run, one K8s Job—compare ops time and report UX.
- **Self-hosted metrics stack:** pipe OSS output to InfluxDB + Grafana ([k6 InfluxDB stack](/en/blog/k6-influxdb-grafana-metrics-stack)).
- **Desktop iteration:** tune in Performate; export script to git for either target ([desktop workflows](/en/blog/desktop-load-testing-workflows)).
- **Secrets never in Cloud project settings** if policy forbids—inject at runtime via CI.

**Anti-patterns to avoid**

- Maintaining two script repos because "Cloud syntax differs"—it should not.
- Choosing Cloud for global load without checking egress allowlists on your API.
- Self-hosting without capacity planning—under-provisioned generators distort results.

**Pro tip (example commands):**

```bash
# Self-hosted
k6 run portable-load.js -e RUN_TARGET=selfhosted -e API_BASE=https://staging.internal.example.com

# Cloud (after login/upload per Grafana docs)
k6 cloud portable-load.js -e RUN_TARGET=cloud
```

**What these commands demonstrate:** identical script and thresholds; only execution plane and env injection change.

## Decision framework: Cloud vs self-hosted vs hybrid

| Situation | Recommended action |
|:---|:---|
| Small team, no ops capacity | k6 Cloud trial; minimize generator ops |
| Strict data residency / air-gapped staging | Self-hosted OSS in VPC; local reports |
| Global latency testing from many regions | Cloud distributed load or multi-region self-hosted |
| Heavy CI smoke only | OSS on existing runners—Cloud optional |
| Need shareable dashboards for PM/QA | Cloud or OSS + Grafana + Performate exports |

**Use k6 Cloud if** ops headcount is scarce and compliance allows scenario metadata off-prem.

**Use self-hosted OSS if** generators, payloads, or URLs must stay inside your network boundary.

**Use hybrid if** engineers iterate locally/desktop, CI runs OSS smoke, quarterly peaks use Cloud burst—same git script for all.

## Observability, documentation, and next steps

Platform choices fail when runbooks assume the wrong target. Before standardizing:

- [ ] Document approved run targets (Cloud, K8s, laptop) and forbidden ones (prod without approval).
- [ ] Record cost model: Cloud subscription vs engineer hours for self-hosted maintenance.
- [ ] Tag runs with `run_target` and archive summaries for comparison pilots.
- [ ] Automate OSS smoke in CI; schedule Cloud distributed runs for release candidates.
- [ ] Align secret injection pattern across Cloud and self-hosted—same env var names.

## How Performate simplifies Cloud vs self-hosted workflows

Splitting iteration across CLI, Cloud UI, and spreadsheets slows adoption. Below is a **concrete workflow example** for portable load testing.

**Example: one desktop workspace, two execution planes**

1. **Import Postman collection** and tune scenario rates in Performate. *Problem solved:* edit load shape once—not separately for Cloud and OSS.
2. **Run locally against staging** for fast iteration. *Problem solved:* no Cloud minutes burned during script debugging.
3. **Export k6 script to git** with env var placeholders for `API_BASE` and `TOKEN`. *Problem solved:* CI self-hosted and Cloud upload share canonical source.
4. **Add tags `run_target` in scenario notes** for reporting consistency. *Problem solved:* compare pilots without rewriting scripts.
5. **Share integrated PDF/JSON report** with PM for sign-off before scaling Cloud distributed test. *Problem solved:* collaboration without mandatory Cloud seats for every viewer.
6. **Trigger Cloud or K8s run** from exported script when staging window opens. *Problem solved:* execution plane becomes ops choice, not rewrite event.

That workflow maps to the `cta`: simplify k6 from imports through results regardless of Cloud vs OSS target.

## Closing takeaway

Cloud vs self-hosted k6 is a **workflow and compliance** decision—not a features checklist. Keep scripts portable, pilot both with the same thresholds, and document who owns generators, secrets, and dashboards before the next peak-traffic rehearsal.

Run this month's pilot with identical `RPS` on Cloud and one K8s Job—note ops time and report shareability, not just the invoice.
