Sourcegraph Cody
Pros
- + Cross-repository context via Sourcegraph's search index — in my testing its citations landed on the real symbols across two repos, where file-scoped assistants hallucinate call sites
- + Context filters actually work: I excluded a repository and confirmed questions stopped drawing from it, a verifiable admin control
- + Runs in VS Code, JetBrains, Visual Studio (experimental), web and CLI, so it fits mixed-IDE teams
- + Enterprise deployment options including single-tenant, with a stated no-model-training policy in Sourcegraph's AI terms
Cons
- - No self-serve access of any kind since 23 July 2025 — no free tier, no trial, and a $16,000 minimum annual contract on the only plan Sourcegraph publishes
- - Per-seat pricing is unpublished; the widely quoted $59/user/month could not be verified on Sourcegraph's own pages
- - Autocomplete latency in a large monorepo was slow enough to interrupt my flow in testing, varying with indexed context size
- - The context advantage depends on your repositories being indexed on the Sourcegraph instance — without that setup it behaves like cheaper assistants
Aider
Pros
- + Free and Apache-2.0 — in my cost tracking a 40-prompt Sonnet session cost about the price of a coffee in API tokens
- + Repository map handled a 7-caller rename in one pass on a 100k-line codebase, beating a paid agent that needed two rounds
- + BYOK with local-model support via Ollama: I completed a refactor fully offline with no code leaving the machine
- + Every change is an auto-committed git commit with a generated message, making each AI step individually revertable
Cons
- - No GUI, no hosted workspace, no preview — terminal comfort is a hard prerequisite
- - No team or enterprise layer: no SSO, audit logs, shared config server or vendor support contract
- - Auto-commits fragment history unless you configure around them
- - Unbounded API spend: heavy all-day use can cost more than a flat-rate subscription tool
