Case Study: How a Community Site Scaled on a Free Host Using Smart Caching & Edge Workflows

Hook: Scaling a community on a free plan sounds impossible. This case study shows how architectural choices — not higher budgets — allowed a volunteer publisher to reach 100K monthly visits without unexpected bills.

Background

The site began as a hobby newsletter and grew into a topical community hub. Early growth exposed two operational weaknesses: slow page loads and brittle deployment workflows that occasionally caused downtime.

Three tactical changes (and impact)

1. Precompute heavy endpoints: The team moved comment counts and leaderboards to nightly precomputed snapshots. This reduced dynamic calls and improved TTFB. The maker case study that reduced TTFB helped inform this approach (read).
2. Edge HTML caching: They configured short revalidation windows for trending pages and longer caches for evergreen content — a balance that maximized freshness and minimized origin pressure.
3. Archive snapshots & rollback: After a major host policy change they restored a static snapshot from their ArchiveBox workflow, avoiding weeks of rebuild work (how‑to).

Operational practices that mattered

• Small, auditable releases: Release notes and public changelogs were published as lightweight docs to keep the community informed; the Compose.page vs Notion comparison helped pick the right public docs tool (compare).
• Link experiments: All channels used link bundles and analytics to measure campaigns; the Weekend Tote review highlights tools that simplify these experiments (read).
• Contact list hygiene: The team adopted minimal retention and consent flows to avoid compliance issues — follow recommended contact list privacy best practices (reference).

"Scale without budget by moving expensive work out of request time and into scheduled builds."

Quantified results

• Monthly visits: from 12K to 100K in 10 months.
• Average TTFB: reduced by ~48% after precomputing key endpoints and edge caching.
• Operational downtime: zero unrecoverable incidents due to the archive and rollback workflow.

Takeaways for other communities

1. Prioritise a single source of truth for content and automate exports.
2. Use edge caching to absorb traffic spikes and protect your origin.
3. Invest an hour per month in archive snapshots and export tests (ArchiveBox guide).

Conclusion: The case demonstrates that architectural focus and a minimal toolkit (edge caching, precomputation and archiving) are more powerful than budget when scaling community sites on free plans.
