Why Empryo

Most coding agents grep, read whole files, and patch strings — they never know what depends on the code they just changed. Empryo builds understanding before it mutates anything:

It maps before it reads. On launch, tree-sitter parses your repo into a live graph — every symbol, import, and call site, ranked by PageRank and git co-change. Graph queries answer in milliseconds and cost zero LLM tokens.
It knows the blast radius. Before an edit, the agent sees what imports a file, what historically changes with it, and how far a change ripples — "what breaks if I touch this?" is answered before the first keystroke.
It edits through the AST. 65+ symbol-level operations, atomic batches with all-or-nothing rollback, structural edits across 30+ languages, and a typecheck as the gate. Nothing breaks on whitespace.
It treats tokens as spend. The graph does the navigation models usually burn context on — fewer reads, fewer steps, smaller bills at any scale.

What's inside


Code genome	live dependency graph: tree-sitter across 30+ languages, PageRank + git co-change ranking, blast-radius tags, millisecond search
Symbol-level editing	65+ AST operations (atomic, with rollback) + structural edits in 30+ languages
Multi-agent	parallel explore/edit agents with a shared I/O cache — cheap models scout, strong models write
Task router	ten routable roles, any model in any seat, per tab — your own mixture of experts
Time machine	every prompt is a git checkpoint; rewind code and conversation together, land on any turn
Three surfaces	native desktop app, full terminal UI, headless CLI for scripts and CI — one genome, three phenotypes
LSP + MCP	576+ language servers via Mason, any MCP server, 13 lifecycle hooks
Free compaction	structural context compaction with no LLM call — long sessions stay cheap

One agent, many brains

Empryo isn't one model in a loop — it's a crew, and you assign the seats. Every role is a routable slot that takes any model from any of the 22 providers:

brain · spark scout · ember code · explore · verify review · goal review · desloppify · summarize · compact · web search

Per tab. Each workspace tab carries its own routing — a frontier model writing code in one tab, a fast cheap one triaging issues in the next, a local model on a private repo in a third.
Per config. Set defaults globally or per project; override any slot from the tab. Cheap models scout, strong models write, reviewers judge with clean context.
Custom agents. Define your own agents — a prompt, a model, a tool policy — and dispatch them alongside the built-ins. Mix and match providers freely inside a single run.
Cache-aware by design. Routing keeps prompt-cache prefixes stable — sub-agents inherit their parent's cache line, so repeated context bills at cache-read rates instead of full price.
Costs, itemized. Live spend tracking per model, per sub-agent, per tab, per session, per day — you always know where the tokens went.

Benchmarks

Head-to-head against pi — same models, same repositories, same tasks. The graph does more with less:

	Round 1 3 bugs × 3 models	Round 2 5 real bugs · hono / zod / ky
Bugs fixed	8/9 vs 7/9	7/10 vs 6/10
Cost	28% lower — $1.13 vs $1.58	23% lower — $7.08 vs $9.19
Wall-clock	57% faster — 4m 16s vs 10m	32% faster — 22m 30s vs 32m 55s
Efficiency	5.7× fewer input tokens — 1.09M vs 6.21M	28% fewer steps — 274 vs 382

Round 2 used real bugs from merged PRs (post-training-cutoff, history scrubbed, regression tests injected after each run). Full methodology and transcripts: empryo.com/benchmarks · reproduce at proxysoul/pi-vs-empryo-bench.

Private by design

Empryo runs entirely on your machine. Bring your own key — Anthropic, OpenAI, Google, Groq, DeepSeek, Bedrock, and 16 more, or any OpenAI-compatible endpoint — or run fully local with Ollama / LM Studio. No proxy in the middle, no code leaving your machine, no per-seat fee. Free to use.

SoulForge

SoulForge remains available to download and install, and continues to receive fixes for bugs and critical issues. New features and active development have moved to Empryo.
