Manifest-driven and Kubernetes-free. Nobody else is both.
Every alternative makes you choose: simple but cloud-locked, or local but Kubernetes-shaped. TDK is the only tool that refuses the trade-off.
Garden, Skaffold and DevSpace assume a cluster. Gitpod and Codespaces assume a credit card. Devbox and Devenv assume Nix. TDK assumes a laptop.

One $19 seat. A full circle of replaced vendors.
Every name in orbit bills you separately — per developer, per month, forever.
Cloud dev environments, priced out
Verified public pricing, September 2026. Estimates assume one full-time 4-core machine per developer.
| Cost | TDK Team | Gitpod / Ona | Codespaces | Coder | Daytona | Okteto |
|---|---|---|---|---|---|---|
| Entry price | $19 / dev / mo | $20 / mo + compute credits | Pay-as-you-go, ~$0.36/hr | Per-user annual | Pay-as-you-go, ~$0.05/vCPU/hr | Free 5 seats |
| Per dev / month, full-time | $19 flat | $20+ compute | ~$58 | ~$50, enterprise | ~$140 | Contact sales |
| 10 developers / year | $2,280 | $2,400 + compute | ~$7,000 | ~$6,000 | ~$16,800 | Contact sales |
| Compute model | Your laptop | Their cloud, metered | Their cloud, metered | Your cloud, you pay | Their cloud, metered | Your cluster, you pay |
| Works offline | Yes | No | No | No | No | No |
| Self-hostable | Local by design | Enterprise tier | Never | Yes | Enterprise tier | Yes |
| Open source core | MIT | Yes | Closed | Yes | Yes | Yes |
Estimates for full-time use of one standard machine per developer, from public pricing pages. Bigger machines, prebuilds and GPU time cost more.
Devbox vs Devenv: Nix-based alternatives
Both are excellent Nix-based tools, but TDK takes a different approach focused on Docker services.
| Feature | TDK CLI | Devbox | Devenv |
|---|---|---|---|
| Primary focus | Docker services | Package management | Full environment |
| Service orchestration | Built-in (Tilt) | process-compose | Native processes |
| Auto-generated Dockerfiles | 10 per service | Manual | Manual |
| Docker Compose generation | Auto-generated | Manual | Manual |
| Hot reload | Built-in | Limited | Manual setup |
| Multi-service discovery | Automatic | Manual | Manual |
| Golden images included | L1–L4 layers | DIY | DIY |
| Nix knowledge required | No | Hidden | Yes |
| Language support | Any (Docker) | 80,000+ packages | 58+ languages |
| CI/CD integration | Native | GitHub Actions | GitHub Actions |
Which tool is right for you?
Choose TDK if you…
Don't know Kubernetes and don't want to learn it. Need services running locally in minutes. Want manifest-driven simplicity. Are a full-stack or product developer. Work at a startup without a platform team — and want your next five hires coding on day one, not week three.
Choose Devbox if you…
Want Nix power without learning Nix language. Need JSON configuration. Prefer simple package management. Want cloud deployment with Jetify Cloud. Are building for cloud-native teams with budget for managed services.
Choose Devenv if you…
Already know Nix or willing to learn. Need maximum reproducibility. Want full environment declaration (languages, services, processes). Are working with complex monorepos. Need fine-grained control over every aspect of your dev environment.
Choose Garden if you…
Have Kubernetes expertise in-house. Need production-like environments for integration testing. Employ a dedicated platform team with time to maintain YAML pipelines. TDK complements this setup nicely for the fast local loop, by the way.
Choose Cloud CDEs if you…
Have budget for cloud spend. Need instant onboarding for remote teams. Want standardized environments without local machine variations. Don't mind working offline or managing cloud costs. Value convenience over control.
The comparison that matters is your invoice
$0 and under 5 seconds of startup — against $20–$150 per developer per month and a YAML learning curve.
