eratosthenes vs Supabase
A side-by-side editorial comparison of eratosthenes and Supabase — release velocity, themes, recent moves, and the top alternatives to consider.
eratosthenes vs Supabase: at a glance
What is eratosthenes?
eratosthenes spends 0.1.0 hardening inputs rather than adding chronology methods.
eratosthenes does Bayesian estimation of archaeological chronologies from relative sequences, absolute constraints and artifact assemblages. The 0.0.9 line built out the inference diagnostics — traceplots, histograms, batch-means MCSE reporting, displacement estimation — and then consolidated artifact probability-density estimation into a single gibbs_ad_type(). The 0.1.0 tag turns outward instead, adding validators for every user-supplied structure and replacing seq_check() with a more informative seq_diag().
What is Supabase?
Supabase is closing its most-exploited default: tables stop being public unless you say so.
The last month is dominated by tightening defaults rather than adding surface. New tables in the public schema will no longer be auto-exposed to the Data and GraphQL APIs, pg_graphql stops being enabled by default, and the OAuth token endpoint is being corrected to return 200 per OAuth 2.1. Alongside that, custom OAuth/OIDC providers landed for Auth and an RLS Tester entered preview.

◆ Current state
eratosthenes does Bayesian estimation of archaeological chronologies from relative sequences, absolute constraints and artifact assemblages. The 0.0.9 line built out the inference diagnostics — traceplots, histograms, batch-means MCSE reporting, displacement estimation — and then consolidated artifact probability-density estimation into a single gibbs_ad_type(). The 0.1.0 tag turns outward instead, adding validators for every user-supplied structure and replacing seq_check() with a more informative seq_diag().
◆ Where it's heading
The package is moving from research code to something a non-author can run. Consolidating estimation behind one function, then wrapping every input class in a validator, are the two steps that make failures legible instead of cryptic, and the diagnostics added earlier serve the same end for the sampler itself. Nothing in the window changes the underlying model; the work is all about making it usable and its output checkable.
◆ Prediction
With inputs validated and diagnostics in place, the next release is more likely to extend the constraint or assemblage modelling than to keep reworking the interface, though the feed's three sparse tags give little to read a cadence from.
Supabase

Supabase is closing its most-exploited default: tables stop being public unless you say so.
◆ Current state
The last month is dominated by tightening defaults rather than adding surface. New tables in the public schema will no longer be auto-exposed to the Data and GraphQL APIs, pg_graphql stops being enabled by default, and the OAuth token endpoint is being corrected to return 200 per OAuth 2.1. Alongside that, custom OAuth/OIDC providers landed for Auth and an RLS Tester entered preview.
◆ Where it's heading
Supabase is paying down the security cost of its own convenience. Auto-exposing every public-schema table made the product fast to start with and easy to misconfigure; the fix is explicit Postgres grants, staged over six months from new projects in April to all existing projects on October 30. The RLS Tester is the same theme from the other side — the auto-exposure default only worked if row-level security was correct, and until now there was no way to check.
◆ Prediction
Expect the remaining rollout dates to hold and more of the developer experience to be rebuilt around explicit grants, with the RLS Tester graduating from preview as it becomes the tool people need to verify the new model. The October cutover for existing projects is the moment where this stops being an announcement and starts breaking things.
