Ship code 24× faster. Inside your network.

Agentic AI coding tools let developers finish features in hours instead of days. The agent reads your codebase, plans the work, writes the code, runs the tests, fixes the errors, and hands you a pull request to review. Recent benchmarks show 2–4× throughput on real engineering work.

Every modern agent runs on the public internet. Copilot, Cursor, Claude Code, Codex — none of them can be installed in an air-gapped network or a regulated private cloud. We deploy the full agentic stack inside your perimeter. Open source. Auditable. Owned by you.

[ SECURITY ]

Built to pass security review. Approved by CISOs in defense and finance.

Every threat we considered. How it's contained. How you verify it.

Data leaves the network
Mitigation:Dedicated VLAN, default-deny egress, firewall whitelist at the boundary.
Verify:Firewall logs — zero external connections during full operation.
Agent reads files outside scope
Mitigation:RBAC inherited from your IdP. Agent inherits the developer's access — never exceeds it.
Verify:Point it at a restricted repo. Confirm 403.
Agent writes malicious code
Mitigation:Code review gate enforced in CI. Every AI-assisted commit flagged. Pre-commit static analysis blocks known patterns.
Verify:Inspect the CI pipeline. Run a red-team commit.
Agent executes destructive commands
Mitigation:Hardware-isolated Firecracker microVM. Default-deny filesystem and network at the kernel level. CAP_SYS_ADMIN dropped.
Verify:Inspect the seccomp profile and capabilities list.
Model contains a backdoor
Mitigation:Open-weight model, SHA-256 verified on transfer, mounted read-only at the OS level.
Verify:Recompute the hash. Diff against the official release.
Prompt injection attack
Mitigation:Every inference logged. SIEM-ready stream. Tool calls run inside the sandbox — no escape path to host.
Verify:Run a red-team prompt. Watch it hit the sandbox boundary.
Supply-chain compromise
Mitigation:Every component built from source against pinned hashes. No closed binaries on classified hardware.
Verify:Your engineers read and rebuild the source.

Autonomy where it's safe. Gates where it matters.

The agent runs inside a hardware-isolated microVM with a default-deny perimeter. Inside that boundary, it works autonomously on routine engineering — reads files in scope, writes code, runs tests, fixes compiler errors. Outside the boundary, every action is blocked at the infrastructure layer. The architecture enforces it. You don't have to.

Read files in scope (RBAC)
Containment:Inherited from developer's permissions.
AUTONOMOUS
Write and modify files in scope
Containment:Sandboxed filesystem. Diff visible in IDE in real time.
AUTONOMOUS
Run tests, compile, lint
Containment:Sandboxed execution. No host access.
AUTONOMOUS
Run shell commands in sandbox
Containment:seccomp-restricted. Linux capabilities dropped.
AUTONOMOUS
Open a pull request
Containment:Final human review at PR stage. Always.
PLAN APPROVAL
Access the public internet
Containment:No route exists. Physically impossible.
BLOCKED
Access restricted repositories
Containment:RBAC denies before request reaches index.
BLOCKED
Modify own weights or infrastructure
Containment:Mounted read-only at OS level.
BLOCKED
Touch production systems
Containment:No path from sandbox to prod network.
BLOCKED

The agent moves at agentic speed inside its lane. Outside its lane, it doesn't move.

[ DEPLOYMENT ]

Your environment. Your rules.

One stack, three deployment modes. Same architecture, same audit trail, same containment guarantees.

[ 01 ]

Air-gapped

Fully disconnected. Model weights transferred on approved media, SHA-256 verified. IDE extensions via your internal mirror. Zero external routes, locked at the OS level.
[ 02 ]

Private cloud

Your VPC, your region. AWS GovCloud, Azure Government, OCI Sovereign, or on-prem OpenShift. All traffic stays in your tenancy.
[ 03 ]

Hybrid restricted

Coding agent inside the perimeter. Opt-in outbound only via a policy-controlled proxy for package registries or documentation.
[ WHAT YOUR DEVELOPERS GET ]

A coding agent that does the work end-to-end

Not autocomplete. An agent that reads, plans, writes, tests, compiles, and opens a reviewed pull request — while you keep working on something else.

[ 01 ]

Reads your codebase

Indexes every repo by function, class, and module. Learns your internal APIs, naming conventions, and architecture patterns.
[ 02 ]

Plans the implementation

Breaks the task into steps across files. Surfaces the plan for review before execution.
[ 03 ]

Writes the code

Multi-file edits that follow your conventions. Uses your internal libraries because it already knows they exist in your repo.
[ 04 ]

Runs the tests

Executes your test suite. Reads failures. Adjusts the code. Re-runs until green.
[ 05 ]

Compiles and fixes

Runs the compiler, parses errors, fixes them, iterates. Works with C/C++, Rust, Java, Go, Python — whatever your codebase uses.
[ 06 ]

Opens a pull request

Hands you a reviewed PR with diffs, test results, and a written summary of what it changed. You review and merge.
Background

See the agent finish a full day's task in 20 minutes.

A live walkthrough on your terms. We deploy the stack on a test machine, give you a real engineering task, and let the agent work end-to-end. Inside a network with zero external connections.

[ ARCHITECTURE — BEST OF WHAT THE WORLD HAS TO OFFER ]

Three layers. All inside your perimeter.

We evaluated every serious AI coding tool on the planet — commercial, open source, and hybrid. These three components, together, are the best the global ecosystem offers for agentic coding inside a perimeter. Every layer is Apache 2.0 or MIT. Self-hosted on standard Linux. No telemetry. No phone-home. Nothing in the path you don't own.

[ 01 ]

Client — your IDE

VS Code, JetBrains, or Eclipse. Cline (Apache 2.0) drives the agent. TabbyML's plugin handles inline completions and repo context.
[ 02 ]

Platform — TabbyML Server

Repo indexing, RBAC, audit logging, SSO with your existing IdP (Active Directory, Okta, internal). Apache 2.0, self-hosted on standard Linux.
[ 03 ]

Inference — vLLM + open-weight model

vLLM serves the model on your local GPUs. Open-weight model of your choice — see the model selection below.
[ MODEL SELECTION ]

Your security policy picks the model.

The strongest open-weight coding models in 2026 are listed below — ranked by current benchmarks, not by what we sell. The stack is model-agnostic. Swap weights, the rest keeps running.

A note on Chinese-origin models

The top four open-weight coding models in 2026 are Chinese. They benchmark hardest, and the data-leak concern that drives most enterprise restrictions doesn't apply here — nothing in our stack ever connects to vendor servers. What does apply: procurement restrictions in defense contracts, supply-chain audit requirements on model weights, and reputational considerations tied to Chinese National Intelligence Law obligations on the upstream developers. Some customers exclude these weights outright. Others accept them after independent weight audit and SHA-256 verification against the official release.

If Chinese weights are off the table, Devstral 2 (agentic) and Codestral 2 (inline / FIM) are the strongest Western-origin alternatives. Devstral 2 is the only Western-origin model that competes at the agentic tier on a single-GPU footprint.

[ TOTAL COST OF OWNERSHIP ]

Roughly one-third the five-year cost. No license. Yours forever.

We're agnostic on build-vs-buy. Some teams need a commercial vendor's support model. Most regulated environments are better served by the open-source path: lower cost, full audit, no license clock ticking. We deliver both.

Hardware (5-year)
Commercial vendor:Vendor-mandated GPU profiles. Roughly 4× more hardware than needed.
Open-source stack (Globalbit):Quantization and serving tuned for your workload and concurrency.
License fees
Commercial vendor:Per-seat, scales with headcount, indexed annually.
Open-source stack (Globalbit):None. Apache 2.0 / MIT across the stack.
Implementation
Commercial vendor:Bundled, opaque, vendor-controlled.
Open-source stack (Globalbit):Transparent. Knowledge transfer included so your team can run it without us.
Updates
Commercial vendor:On the vendor's schedule, at the vendor's price.
Open-source stack (Globalbit):Open-source release cadence. You decide what to deploy and when.
After year 5
Commercial vendor:Renewal, re-platforming, or shutdown.
Open-source stack (Globalbit):You own the stack. Run it as long as you want.
Source code access
Commercial vendor:Closed binary on your classified hardware.
Open-source stack (Globalbit):Every line readable by your security team.
5-year total
Commercial vendor:Baseline
Open-source stack (Globalbit):Roughly one-third of the commercial vendor.

[ FAQ ]

Frequently Asked Questions

How is this different from GitHub Copilot, Cursor, or Claude Code?

Every cloud-based AI coding tool — Copilot, Cursor, Claude Code, Codex — sends source code over the public internet to vendor servers. In an air-gapped network or a regulated private cloud, that's not an option. Our stack runs entirely inside your perimeter. The inference engine, the model weights, the IDE agent, and the platform all live on your hardware. No external routes exist.

Is this an open-source alternative to Tabnine?

What models can run on-premise in an air-gapped network?

How do you update the model and software without internet access?
