Empryo vs Aider
Aider is a lightweight, open-source AI pair programmer for the terminal. It commits its changes to git as it goes and builds a repo map with Tree-sitter so the model knows what is where. Empryo shares the repo-map idea: it builds the Genome, a map of every file, symbol and import. It adds edits by symbol name, language-server renames, a desktop app and a headless CLI.
Two terminal pair programmers that both start from a map of your repo.

Side by side
| Feature | Empryo | Aider | In short |
|---|---|---|---|
| Repo map | The Genome: files, symbols and imports, with a count of how many files depend on each one. | A Tree-sitter repo map of files and symbols. | Much alike Both start from a map of files and symbols. Empryo's also counts how many files depend on each one. |
| How edits are made | By symbol name. TypeScript and JavaScript edits go through the syntax tree; renames use the language server. | Text edits in several formats, such as search and replace blocks or whole files. | Different approach Empryo edits by symbol name. Aider edits text, for example with search and replace blocks. |
| Undo | Checkpoints that roll back code and conversation together. | A git commit for each change. | Different approach Aider makes a git commit for each change. Empryo rolls back code and conversation together. |
| Where it runs | Desktop app, terminal UI and headless CLI. | Terminal, with an optional browser UI and scripting. | Different approach Both run in a terminal. Empryo adds a desktop app; Aider adds an optional browser UI. |
| Source | Closed source. You use your own model keys or local models. | Open source (Apache 2.0). | Different approach Aider is open source under Apache 2.0. Empryo is closed source. |

Which one fits
Choose Empryo if
Choose Empryo when you want the agent to do more of the work and to edit by structure. Empryo's agent runs tools, reads code by symbol and makes multi-file changes, using the language server for renames so every reference moves together. It can run helper agents in parallel, assign a different model to each kind of job, and roll back code and conversation together with checkpoints. It also has a desktop app if you don't want to work only in the terminal.
Choose Aider if
Choose Aider when you want a small, open-source tool with a simple, predictable workflow. You add the files you want it to work on, it edits them, and it makes a git commit for each change, so undoing is just a git command. It works with many models and has a long track record.
Bottom line
Aider is a simple, dependable open-source pair programmer with a clean git workflow. Empryo builds on the same repo-map idea and adds symbol-based edits, language-server renames, parallel helper agents and a desktop app. Pick Aider for simplicity and openness. Pick Empryo if you want the agent to handle larger, multi-file changes with structural edits.
Common questions
How is Empryo's Genome different from Aider's repo map?
Both give the model a summary of where things are in your repo. Empryo's Genome also records imports between files and how many files depend on each one, and it updates as files change, so the agent can see what a change will affect.
Does Empryo commit to git like Aider?
Empryo uses checkpoints instead of committing every change. A checkpoint lets you roll back both the code and the conversation. You decide when to commit.
Can both use local models?
Yes. Both can use local models. In Empryo, Ollama and LM Studio are built in, and any OpenAI-compatible server can be added with a short config block.
