In One Week I Rebuilt My Entire $500/Month SaaS Stack with Scripts
Published Feb 25, 2026 · 8 min read
In seven days I rebuilt the core of my paid SaaS stack using scripts, LaunchAgents, and a local AI model. This wasn’t a “toy project.” It runs real businesses, posts across multiple accounts, publishes blogs, updates dashboards, and deploys sites. The punchline: the stack costs me $200/month (Claude Code), vs an estimated $500+ / month in SaaS subscriptions.
Why I rebuilt it
I was paying for separate tools to schedule posts, publish content, manage product feeds, update dashboards, and run automations. Each tool was “reasonable” on its own, but the combined cost was hundreds per month. I wanted ownership, speed, and a stack I could extend without adding another bill.
What I built (real features)
- Social scheduling: Multi‑account posting + queues + timed runs for 7 X accounts.
- Content publishing: Daily blog generator + auto‑deploy for multiple sites.
- SEO ops: Auto‑updated blog indexes + sitemaps.
- Marketplace ops: Walmart/TikTok/Pinterest feed pipelines and listing automation.
- Dashboards: Daily revenue/P&L dashboards updated from logs.
- Workflow automation: LaunchAgents + watch‑based deploys instead of SaaS triggers.
The architecture (simple on purpose)
- Mac mini running scripts + LaunchAgents (native scheduler)
- Local/hosted LLM for content generation + summaries
- Static sites on Cloudflare Pages (fast, free hosting)
- Git as the source of truth + auto‑deploy on change
What I didn’t replace
Some SaaS platforms have mature UI/teams features I didn’t need. My goal was operational leverage for a solo operator, not multi‑team workflows or client portals.
Lessons learned
- Ownership beats convenience. Once you own the pipeline, changes take minutes instead of vendor tickets.
- Small scripts compound. A 40‑line script can remove a $50/mo fee forever.
- Deploy is the bottleneck. Auto‑deploy + homepage refresh made “daily publishing” real.
Before / After cost (estimated)
| What it does | Commercial tools | Est. monthly cost |
|---|---|---|
| Social scheduling / queues | Hootsuite, Buffer, Sprout, Typefully | $50–$200 |
| AI content generation | Jasper, Copy.ai, Frase | $59–$199 |
| CMS + publishing | Webflow CMS, Ghost | $29–$79 |
| Workflow automation | Zapier, Make, n8n Cloud | $20–$99 |
| Marketplace feeds | Feedonomics, Sellbrite, GoDataFeed | $99–$399+ |
| Dashboards / reporting | Databox, Geckoboard, Baremetrics | $39–$199 |
| Pinterest scheduling | Tailwind, Later | $19–$49 |
| Estimated total (commercial stack) | Combined tools above | $315–$1,224+ |
| My stack (after) | Claude Max (automation + generation) | $200 |
| Estimated savings | Commercial stack minus Claude Max | $115–$1,024+/mo |

Bottom line: The point isn’t that SaaS is bad — it’s that as a solo operator you can replace a surprising amount of it with small scripts and a focused stack. If you want ownership, lower burn, and speed, this is worth doing.
