The verdict in three sentences
The right stack is not the trendiest, it is the one that minimizes total cost: development, hiring, maintenance and hosting. In 2026, a Next.js + Node + PostgreSQL base covers 90 % of business web apps with a mature ecosystem and easy-to-hire developers. Avoid the exotic stack that ties you to three unfindable experts and doubles your maintenance bill.
Stack comparison for 2026
Each stack has a cost and scalability profile. Here are the 2026 orders of magnitude for an SME business app.
| Stack | Profile | Hosting/month | Hiring | Scalability |
|---|---|---|---|---|
| Next.js + Node + PostgreSQL | Versatile, mature | EUR 100 - 400 | Easy | High |
| Next.js + Supabase | Fast to launch (BaaS) | EUR 80 - 300 | Easy | Medium-high |
| Laravel + MySQL | Classic back office | EUR 60 - 250 | Easy | Medium |
| Django + PostgreSQL | Data / Python | EUR 100 - 400 | Medium | High |
| Exotic stack (niche) | Specific performance | EUR 150 - 600 | Hard | Variable |
Hosting cost is rarely the deciding factor: the gap between EUR 100 and 400/month is marginal against a developer's cost (EUR 350 to 600/day) and hiring ease.
The criteria that really matter
Beyond fashion, four criteria decide. This table prioritizes them.
| Criterion | Why it is key | 5-year impact |
|---|---|---|
| Maturity / stability | Fewer bugs, solid docs | -20 % maintenance |
| Developer talent pool | Faster, cheaper hiring | -15 to -30 % HR cost |
| Ecosystem (libs, tools) | Less code to write | -10 to -25 % dev |
| Hosting cost | Marginal below 10k users | +/- EUR 3,600/year |
The golden rule: pick a stack where you can replace a developer in 2 weeks. A niche technology, however brilliant, creates a continuity risk that costs far more than a few milliseconds of performance.
Mini case study
Nadia, CTO of a services SME in Marseille, is torn between an exotic "high-performance" stack and Next.js + Node + PostgreSQL. The initial quotes are close: EUR 72,000 vs EUR 68,000.
But over 5 years, the niche stack needs 2 experts at EUR 550/day, hard to replace, against abundant Next.js devs at EUR 420/day. On maintenance (estimated 40 days/year), the gap is (550-420) x 40 = EUR 5,200/year, or EUR 26,000 over 5 years, before counting the standstill risk if an expert leaves. She picks the mature stack.

FAQ
Should I always pick the newest stack?
No. A too-recent technology lacks maturity, libraries and available developers. In 2026, favor a proven stack (Next.js, Node, PostgreSQL) with at least 3-4 years of production track record.
Supabase or a classic PostgreSQL database?
Supabase speeds up launch (auth, auto API) and suits MVPs and medium apps, EUR 80-300/month. For heavy business logic or high volume, a directly managed PostgreSQL gives more control.
How much does hosting a business app cost?
Between EUR 100 and 500/month in 2026 depending on traffic and data. That is marginal against development cost: do not optimize the stack just to save EUR 200/month of hosting.
Does the stack affect hiring cost?
Hugely. A large talent pool (JavaScript, PHP, Python) cuts lead times and salaries by 15 to 30 %. A niche technology raises day rates and stretches hiring to several months.
Can I change stack later?
Yes but it is costly: a partial rewrite is 30 to 60 % of the original cost. Better to choose a mature, scalable stack from the start, even if it costs a bit more at launch.
