DeepSeek vs Sourcegraph Cody
A plain-English comparison to help you choose between them.
Free frontier-class models against an enterprise codebase platform, and the budgets they answer to barely touch: DeepSeek collapses the cost of coding capability, Cody sells understanding of an estate. Pick DeepSeek when spend or control is the constraint, free capable chat, a volume-undercutting API, open weights for private deployment, its own agent harness still a developer preview. Pick Sourcegraph Cody when the constraint is comprehension across thousands of repositories, completions and answers grounded in how the code actually connects, with cross-repo impact analysis before changes land, bought through enterprise procurement.
Both tools chosen. Compare is enabled.
Side by side
- Summary
DeepSeek is the price disruptor at the frontier: a free, capable chat assistant, an API priced far below the western frontier labs, and open-weight model releases that anyone can download and run. Successive model generations have kept it genuinely competitive on reasoning and coding, not merely cheap.
The open weights are the strategic fact. Organisations that cannot send data to a Chinese-hosted service can still use the models by self-hosting them on their own infrastructure, which splits the privacy question from the capability question.
MoreLess
For cost-sensitive builders and self-hosters it is a serious default; for regulated data on the hosted service, the jurisdiction question is the one to answer first.
- Best for
- A free, genuinely capable chat assistant
- The lowest-cost frontier-grade API for builders
- Open weights you can download and self-host
- Reasoning and coding strength per pound spent
- Privacy-critical use via self-hosted deployment
- Cost
- Freemium (Free tier + paid plans)
- Ease
- Openness
- Runs privately (self-hostable)
- Data
- The hosted service processes data under Chinese jurisdiction, which rules it out for sensitive work; self-hosting the open weights removes that concern entirely.
- Summary
Cody is Sourcegraph's enterprise coding AI, built on the code-intelligence platform that indexes very large, multi-repository codebases. Its context is the differentiator: answers, completions and edits grounded in how code actually connects across an organisation's repos, with cross-repo impact analysis the marquee capability.
It is now enterprise-only by deliberate strategy: the free and individual tiers were retired, with individuals directed to a separate spun-off agent product. Cody's audience is the organisation whose codebase is the problem.

For teams inside that shape, few tools see the whole estate the way it does.
- Best for
- Multi-repo and monorepo context at enterprise scale

- Code intelligence and AI in one platform
- Organisations whose codebase outgrew single-repo tools
- Cost
- Freemium (Free tier + paid plans)
- Ease
- Openness
- Hosted service
- Data
- Enterprise deployments keep code context inside your environment with admin controls fit for security review.

By area
Where each one pulls ahead, area by area.
| Area | DeepSeek | Sourcegraph Cody |
|---|---|---|
| By job | ||
| Software development | DeepSeek makes jurisdiction the fork in the decision and answers it by self-hosting the weights, at the cost of an infrastructure project | Sourcegraph Cody standardises AI assistance under enterprise controls, so what a team may do with it is decided once rather than per developer |
| By task | ||
| Coding & software development | DeepSeek — when coding AI spend matters, or you want strong open weights you control | Sourcegraph Cody is enterprise-only by deliberate strategy, so evaluating it means evaluating the Sourcegraph platform rather than a component of one |
Common questions
Could cheap models replace the platform?
Only by rebuilding it. Cody's substance is Sourcegraph's code intelligence, the index of how an organisation's code connects, which no model subscription supplies however capable the model. An enterprise could wire DeepSeek's weights into bespoke tooling, a genuine platform programme, which is exactly the build-versus-buy decision this pair actually poses beneath its surface.
Who can buy each in practice?
Opposite doors. DeepSeek's chat is free and its API a card away, adopted by an individual this afternoon, with self-hosting open to any team with GPUs. Cody retired its free and individual tiers by deliberate strategy: enterprise procurement is the way in, individuals were pointed at a separate product line, and evaluating it means evaluating the platform.
How do their governance stories compare?
A fork against a contract. DeepSeek's hosted service processes data under Chinese jurisdiction, failing many policies, while its open weights self-host with nothing leaving your infrastructure, licence terms verified per release. Cody answers governance contractually, enterprise controls that satisfy security review inside the platform's walls, the conventional posture regulated buyers already know how to assess.
