Know the rate first
The model’s rate is under the composer before you send and the cost is printed on the answer — not a bill in a currency you cannot price.
Against the alternatives
Every cell in the table below comes from the competitor’s own published pages, quoted rather than characterised. Where a page does not answer the question, the cell says “not published” — on a table whose headline is that nobody publishes the price, that is the answer.

What it actually asks
The model’s rate is under the composer before you send and the cost is printed on the answer — not a bill in a currency you cannot price.
300+ models, each priced, instead of one fixed model or a paid-tier-only picker.
You pay for what ran, not for credits that expired before you used them.
From the first turn — not an export button you have to remember to press.
Portable markdown, not a black box only their own app can read.
Your own keys, your own hardware, nothing reaching us.
What it costs, at your usage
Three questions, one slider each: what a month of asking costs, what a month of building costs, and what it costs as people join. Ours is the only line on any of the three charts that moves, because everybody else sells a flat subscription — and a flat bar is not “cheaper”, it is the price of a box whose contents they do not publish. Every rival figure comes from that rival’s own published page, dated in the caption — and where a page would not give us one, the bar says so instead of guessing.
If every single answer used a frontier model at $0.05 instead, the same plan would be $33.49 — the worst case, not the normal one.

Replit, Bolt and Base44 columns from replit.com, bolt.new and base44.com as published on 29 August 2026; Replit Core is $20 a month with “$20 towards most powerful models”, Bolt Pro is $25 for 10M tokens, Base44 Starter is $16 for 100 message credits. Lovable and Retool figures from lovable.dev and retool.com as published on 27 August 2026 — Lovable Pro is $25 a month for 100 credits, Retool Business is $50 per builder per month billed annually. “Not published” means their page does not answer the question — which, on this table, is the finding.
The question that decides it
Credits are a currency with no published exchange rate. Seats are a bill that arrives whether anyone built anything or not. Here the unit is a dollar: what the provider charged us plus 20–30% — 30% on the trial, Amelia’s Chat AI and Pro, 28% on Pro Plus, 22% on Pro Max — with that rate under the composer before you send and what the answer cost printed on the answer. Free to start with no card, chat from $4.99 a month and building plans from $10 a month billed annually, and a spending limit on from day one.
The table concedes points on purpose — Base44’s two-way GitHub sync and published model select, Bolt’s open-source sibling — because a comparison that cannot concede a point is an advert. Check every cell against their pages; that is the point. And if you want to know who is making these claims: a software company that has shipped for other businesses since 2005.
One at a time
The table above is for weighing all five at once. If you have narrowed it to one, each of these answers that comparison on its own — same sourced cells, none of the noise from the others. Every alternative page on this site, one place, sorted by what it replaces.

Questions
Amelia's Agent publishes the model's rate under the composer before you send and prints what the answer cost on the answer. Lovable, Replit, Bolt and Base44 bill in credits, tokens or 'effort' that are priced after the work has happened.
Amelia's Agent offers 300+ models, each with its published price shown before you spend anything. Base44 publishes model selection on paid plans. Lovable does not offer a choice, and Replit and Bolt do not publish one.
Amelia's Agent has a self-hosted path: the same agent on your own hardware with your own model keys, and we charge nothing for it. Bolt has an open-source sibling, bolt.diy, which also runs on your own keys. Retool self-hosting is still billed per seat.
