Paideralpha
An AI coding agent written in PHP — that can tell you what it cost.
Install
composer require paider/paider # inside your Laravel app
composer global require paider/paider # as a standalone CLIOr via this domain, which is what you are looking at:
curl -fsSL paider.dev/install | sh
That script installs through Composer. It checks for PHP 8.4+ and the twelve
extensions Paider actually loads, then hands off to composer global require.
It is not a standalone binary — that channel is still deferred.
What it does
- Four named model tiers — orchestrator, coder, research, fast — so the model that plans is not the model that greps.
- A cost ledger that reconciles. Priced per model at write time and never re-priced on read, so replaying the log cannot rewrite what a past session cost. It is checked against provider-reported usage by a live test, not by assertion.
- An append-only event log. The ledger is a pure projection over it.
- An approval gate in front of every tool, with path containment and secret redaction.
- Eleven model presets, every id and price verified against the live catalogue.
What it does not do
Do not install this expecting a finished agent.
The wiring is real and tested. The last mile is not: nobody has yet watched Paider drive
an end-to-end multi-file edit in a repo that is not its own. That milestone is tracked
openly in PLAN.md and it is not met.
- No standalone binary yet — the FrankenPHP embed has known packaging problems.
- No MCP client yet.
- Sessions, memory and the response cache are designed, not built.
