My 2026 stack as a solo engineer

The exact tools I use to ship side projects and client work in 2026. Each picked for low operational cost, low monthly bill, and high leverage.

I run sarmalinux.com plus four to six client projects at any given time, solo. Here is what runs the show in 2026.

The full stack

My 2026 stack and what each costs me

BookingCal.com self-hosted£0Full control
AI primaryGroq + Vertex Gemini Flash£20-40/moCheap, fast
AI fallbackOpenRouter£0-30/moMulti-model failover

Total recurring cost: roughly £160-280/month depending on traffic and usage[1][2]. Not nothing, but every line item earns its place.

Selection criteria

I pick a tool if it meets three tests:

  1. Time-saving > cost. I value an hour of my time at £40 minimum, more for client work. A £25/month tool that saves me 1 hour/month pays for itself.
  1. Operational simplicity. A tool I do not need to think about. I am the operations team; if a tool wants 10 hours of upkeep a month, it is out.
  1. Reasonable lock-in. Vercel I can leave for AWS in a week. Supabase I can leave for Postgres-anywhere in two days. Avoid tools that are commercially impossible to leave.

Why I do not have

  • A separate logging stack. Vercel logs + Better Stack covers it.
  • A separate APM. Vercel insights is enough for a solo.
  • A team chat. Apple Messages with myself is the team chat.
  • A project management tool. Linear for client work, plain markdown for my own.
  • A separate auth provider. Supabase Auth.

The unsung heroes

Resend is the email tool. Free tier is generous and the DX is the best in the category.

Better Stack for uptime. £24 covers me; the free tier is fine until you have a few production endpoints.

Plausible self-hosted for analytics. £0 since it runs on a £6/month Hetzner box I already have.

What I would change at scale

If I were running this with a team of three:

  • Add Sentry instead of relying on Vercel logs (£26/mo)
  • Add Linear instead of markdown (£10/mo per seat)
  • Add a secrets manager (1Password or Doppler)

For solo, the simplicity wins.

About the data

A note on what the numbers in this post represent so you can read them with the right confidence:

  • "My own bench" rows are personal measurements on my own hardware. They are honest about my setup and reproducible there, but they should not be treated as universal benchmark scores.
  • Benchmark numbers attributed to public sources (Geekbench Browser, DXOMARK, NotebookCheck, FIA timing) are illustrative, the trend is what matters, not the third decimal place. Cross-check against the source for anything you would act on financially.
  • Client outcomes and ROI percentages in business-focused posts are anonymised composites drawn from my own consulting work. Real numbers, real direction, sanitised so individual clients are not identifiable.
  • Foldable crease-depth and similar engineering measurements are estimates pulled from teardown reports and reviewer claims; manufacturers do not publish these directly.
  • Forecasts and "what I bet" lines are exactly that, opinions, not predictions with a track record yet.

If you spot a number that contradicts a source you trust, tell me, I would rather correct it than be the chart that was off by 6 percent and pretended otherwise.
