An agent that reads, edits and runs the code of your projects, connected to the model of your choice — DeepSeek, Anthropic, OpenAI or your own endpoint. Installed and maintained by DINAO, isolated in your container, hosted in France.
DeepSeek Harness is a development agent released as free software (MIT licence) by DeepSeek. In your browser, you give it a task — fix a bug, write a test, reorganise a module — and it reads your files, proposes and applies changes, runs the commands it needs, then reports back.
It does not provide a model: in its interface you enter the key of the provider of your choice (DeepSeek, Anthropic, OpenAI, Mistral and some forty others) or the address of an OpenAI-compatible endpoint you host.
At DINAO, it runs in a container reserved for you: your projects stay in your space, and the publisher's telemetry is disabled. No data is passed to a third party by DINAO: the only requests leaving your container are those you trigger, to the model provider you have chosen.
DeepSeek Harness is a trademark of DeepSeek. DINAO hosts the software as released by its publisher, without any partnership with it.
Resource tiers compatible with DeepSeek Harness prerequisites (minimum 1 vCPU / 1 Go / 10 Go). Hosted in France, fully managed.
From the simplest to the most flexible: DINAO takes care of everything on a shared server, DINAO installs and manages DeepSeek Harness on a machine that is yours alone, or you administer your own virtual private server.
Option 1 The simplest
from €9,90 /month excl. VAT
To get started quickly, with nothing to administer.
Choose a tier ↓Option 2
from €28,70 /month excl. VAT
To isolate a production application on a VPS without administering it.
Order →Option 3 100% self-managed
from €11,00 /month excl. VAT
By default you keep full control; but without an additional service, you handle everything: maintenance, configuration, deployment.

Self-hosting DeepSeek Harness means a server to maintain, security updates, backups and monitoring. With our managed DeepSeek Harness hosting, you use the application: we run the infrastructure.
The container hosts the application, not the AI engine (which requires dedicated GPUs) : inference is handled externally, with your own provider key. Prioritize a sovereign engine — Mistral AI, NumSpot, Scaleway, or OVHcloud AI Endpoints (France, GDPR) ; an international provider (OpenAI, Anthropic…) only if a specific capability requires it. Inference subscriptions are not included in hosting.
Yes. DeepSeek Harness does not provide a model: in its interface you enter the key of the provider of your choice (DeepSeek, Anthropic, OpenAI, Mistral and some forty others), or the address of an OpenAI-compatible endpoint you host. Model usage is billed by your provider, not by DINAO.
The publisher's telemetry is disabled in your container, and no data is passed to a third party by DINAO. Your requests go to the model provider you choose: if it is DeepSeek, they go to DeepSeek; if it is another one, they do not.
At startup, the software writes a personal sign-in address to its log: you open it once from the “Logs” tab of your service, in your client area, and your browser then stays signed in. Restarting the container writes a new address.
Its commands are confined by the kernel: they only write to your working folder. It does keep Internet access, like a developer. Use a dedicated API key, with a spending cap at your provider.
No: the publisher presents it as a pre-release and announces incompatible changes from one version to the next. DINAO pins a tested version and only changes it after testing it.
At rest, the software uses about 250 MB of memory; it is your tasks (builds, tests, your projects' dependencies) that need more. The Discovery plan is enough to get started and for everyday use; move to Standard if your projects build a lot or run heavy test suites.
On DINAO's infrastructure in France, in one of the available datacentres. Your projects do not leave the country.
Yes. Version 0.2.2-rc.1 was deployed on our infrastructure on 6 November 2026 and its start-up was checked automatically: every expected service must respond for this page to carry this statement. The deployment template used was last updated on 6 November 2026. Each new version released by the publisher triggers this test again: the date above therefore follows the version actually offered.
DINAO's managed service is included in the price of your container. It covers the technical operation of the server and its software layers: operating system, database, runtime environment and application (installation, security updates, backups, monitoring). It does not include help with the day-to-day use of the application, which remains the customer's responsibility. It is provided on a best-effort basis, under an obligation of means: your requests are handled according to their nature and criticality, in the order of priority set by DINAO, taking particular account of the impact on service availability. No response or restoration time is guaranteed at this level. Technical monitoring is automatic, 24 hours a day, 7 days a week: an outage is detected without any action on your part. Human interventions take place Monday to Friday, excluding public holidays.
If your business needs a guaranteed response time, two “Support responsiveness” options can be taken out when ordering or during the contract:
– Priority handling (€15 excl. VAT/month): handling by a technician within 2 hours (guaranteed intervention time, GTI);
– Enhanced priority handling (€35 excl. VAT/month): handling within 30 minutes and restoration within 4 hours (GTI and guaranteed restoration time, GTR).
These times are counted only from 9 a.m. to 5 p.m., Monday to Friday, excluding public holidays. Time not elapsed at 5 p.m. resumes on the next working day: with a 2-hour GTI, a request received at 4:30 p.m. is handled at the latest at 10:30 a.m. on the next working day. The GTI guarantees the start of handling, not the resolution. For extended backup retention or a copy on a second site, contact our Application Container department.
Yes. The software does not provide a model: the user enters in their interface the key of their chosen provider (42 providers in the software's catalogue, including DeepSeek, Anthropic, OpenAI, Mistral) or the address of an OpenAI-compatible endpoint. The usage of the model is billed by this provider.
The vendor's telemetry is disabled in the container (DSH_TELEMETRY_DISABLED and DSH_TELEMETRY_MODE=DISABLED): no unsolicited outbound connections have been observed in testing. Requests are sent to the model provider chosen by the client; no data is transmitted to a third party by DINAO.
At startup, the software logs a token address in its log file; opening it once grants the browser a 30-day session. A restart generates a new token (the previous one is rejected) without interrupting active sessions.
Major version upgrades are not included in managed services: they modify the application itself — data schema, extensions, configuration — and may render it inoperable. DINAO, however, offers a protected automatic update option: a full backup is taken, the new version is installed, and then the service startup is automatically verified. If the service does not restart correctly, the previous version and the backup are automatically restored — your application returns to its previous state. This option covers updates within your major version; moving to a higher major version remains your decision and may be subject to a support service.
Yes, for 24 hours: the old address automatically redirects (302, path preserved) to the new one, and then the redirect is removed. Before saving, the dashboard checks that the new address points to the container's server and indicates the DNS record to create if not; the client can also make the www variant respond. The HTTPS certificate is obtained automatically.
Not contractually: automatic 24/7 monitoring, with human intervention on working days; out-of-hours intervention remains possible without commitment.
Yes, upon request. The included managed services are provided on a "best effort" basis with no guaranteed response time. Extended managed services packages can be set up — including priority handling, extended intervention windows, time commitments, extended backup retention, and replication to a second site. Their content and pricing are determined on a case-by-case basis with the client: as of today, there is no public catalogue of packages or online-purchasable options. Requests should be submitted via the Application Container service (Support Department #12, conteneur@dinao.com).
