Turso vs Supabase: pricing, billing model and which to choose

1. Two different models, not two comparable prices#

Turso and Supabase solve the managed database problem with different ideas. Turso offers SQLite-compatible databases and charges per rows read and written plus storage. Supabase offers PostgreSQL with authentication, files and functions, and charges a monthly plan plus project compute, disk and egress.

That is why comparing only the entry price misleads: what matters is what grows with your usage. The table summarizes the model differences; the prices are those on each provider's official pages, read on October 17, 2026.

2. Turso's plans#

Turso has four plans with included quotas and an overage price per unit. Paid plans allow an unlimited number of databases. Prices are in dollars per month.

Supabase prices are in the Supabase pricing guide and in the Free vs Pro comparison. In short: Free costs nothing with 500 MB and 2 active projects; Pro starts at $25 a month with $10 of compute credits and 8 GB included.

3. Three calculated workloads#

To see how each model behaves, the code calculates the best Turso plan and the Supabase Pro cost for three workloads. It is an estimate: Supabase does not bill per row but its capacity depends on compute, and Turso does not reserve compute. The large example includes $50 extra compute (a Medium instance).

TURSO = {  # plan: (base, GB incl., reads incl. in M, writes incl. in M, USD/GB extra, USD per 1,000 M extra reads, USD per M extra writes)
    "Free": (0.00, 5, 500, 10, None, None, None),
    "Developer": (4.99, 9, 2_500, 25, 0.75, 1.00, 1.00),
    "Scaler": (24.92, 24, 100_000, 100, 0.50, 0.80, 0.80),
    "Pro": (416.58, 50, 250_000, 250, 0.45, 0.75, 0.75),
}

def turso_cost(gb, reads_m, writes_m):
    best = None
    for plan, (base, gb_inc, read_inc, write_inc, r_gb, r_read, r_write) in TURSO.items():
        if r_gb is None:  # Free: only if it fits within what is included
            if gb > gb_inc or reads_m > read_inc or writes_m > write_inc:
                continue
            total = base
        else:
            total = (base + max(0, gb - gb_inc) * r_gb
                     + max(0, reads_m - read_inc) / 1_000 * r_read
                     + max(0, writes_m - write_inc) * r_write)
        if best is None or total < best[1]:
            best = (plan, total)
    return best

def supabase_pro_cost(gb, extra_compute=0.0):
    return 25.0 + extra_compute + max(0, gb - 8) * 0.125

workloads = [("Small", 2, 200, 5, 0.0), ("Medium", 12, 4_000, 60, 0.0), ("Large", 40, 30_000, 300, 50.0)]
for name, gb, reads_m, writes_m, extra_compute in workloads:
    plan, total = turso_cost(gb, reads_m, writes_m)
    print(f"{name}: Turso {plan} {total:,.2f} | Supabase Pro {supabase_pro_cost(gb, extra_compute):,.2f}")

With small workloads, Turso Free costs nothing and Supabase needs Pro because 2 GB exceeds Free's 500 MB. On the medium workload the prices almost coincide. On the large one, Turso's write billing dominates ($160 of the $192.92) while Supabase Pro with Medium compute comes to $79: there, the capacity you need weighs more than the per-row price.

4. Which to choose for your case#

There is no overall winner. The table turns the criteria into decisions.

Before deciding, estimate your rows read and written per month: it is the figure that changes Turso's cost the most. For Supabase, estimate disk size and compute.

5. If you migrate between them#

Moving from SQLite to PostgreSQL (or the reverse) is not just changing the connection string.

• Data types: PostgreSQL is strict about types; SQLite is more flexible. Review dates, booleans and large integers.
• Functions and extensions: anything that depends on PostgreSQL extensions does not exist in SQLite.
• Concurrency and transactions: locking models differ; test your concurrent writes.
• Tools and ORM: confirm your ORM supports both dialects and test migrations in a staging environment.

6. Keep your numbers current#

Plans and quotas change. The figures in this guide are those on the official pages on October 17, 2026; confirm the conditions before deciding.

• Note the date you read each rate.
• Measure your real rows read and written for a month before choosing a Turso plan.
• Compare more options in Codifly's database comparator.
