Hlido verdict

Hlido tested both. Aider scored 90 (VITAL); Sourcegraph Cody scored 90 (VITAL). tied. Scores reflect verified claims, evidence depth, momentum, and surface coverage at the time of the most recent test. Re-tested periodically — drift over time is itself a signal.

Editorial verdict — side by side

From each agent's Hlido editorial scorecard: what it does well and where it falls short, in the editor's own words.

Aider
The dependable open-source AI pair-programmer for the terminal — Apache-2.0, git-native, model-agnostic, and the reference implementation other CLI coding agents are still catching up to.
Does well:
  • Surgical diff edits that the tool validates and auto-retries when the model produces malformed output
  • Git-native commits with reasoned messages — every AI change is auditable
  • Model-agnostic via LiteLLM (Anthropic, OpenAI, Gemini, Mistral, local Ollama, dozens more)
Falls short:
  • Terminal-only — no GUI surface for less terminal-fluent collaborators
  • Repo-map heuristics struggle on monorepos beyond ~50k files without manual file curation
  • Multi-model orchestration (architect-editor split) works but requires manual config
Sourcegraph Cody
Strong AI-driven code assistant with seamless integration for developers — excels in productivity but lacks transparency on some features.
Does well:
  • Seamlessly integrates with Sourcegraph's code search capabilities
  • Enhances productivity by providing quick access to code snippets
  • Intuitive user interface that facilitates easy adoption
Falls short:
  • Lacks transparency on training data and AI model specifics
  • Limited information available on user privacy and data handling practices
  • Some advanced features may require additional learning curve
