The AI coding agent for C and C++Writes C++.
Proves it compiles, runs, and passes.
ByteAsk writes the change, then builds it, runs your sanitizers and tests, and joins the gdb session you already have open. You review a diff that already compiles and passes.

The questions that decide it
Why use ByteAsk instead of Claude Code, Cursor or Codex?
Claude Code, Cursor and Codex are general-purpose coding agents. ByteAsk is built only for C and C++, and no fix reaches you until it has been compiled, run under the sanitizers and run against your tests.
When your program crashes or hangs, ByteAsk joins the gdb session you already have open, with your breakpoints and state intact.
Our own models are trained with reinforcement learning against the compiler, the sanitizers and real test suites, and every session comes with 35 built-in tools across your toolchain.
It also comes with the specs your code has to obey: MISRA, AUTOSAR, the Arm, STM32 and x86-64 manuals, and exchange protocols like FIX and ITCH.
Why can another agent not just run gdb on my process?
Linux gives each process exactly one tracer, and while your gdb is attached, that tracer is your gdb. A second debugger gets Operation not permitted from ptrace. An agent that shells out to gdb can still run it in batch mode on a process nobody is debugging, but it cannot join the session you are sitting in. ByteAsk connects through a bridge you start inside your own gdb, reads the stop state, and proposes any command that would change it. You can check the lockout yourself: while your gdb holds a process, run gdb -p <pid> in another shell.
Do I have to use your models?
No. Sign in and use OpenAI, Anthropic and Google models through ByteAsk with no API key to paste, or bring your own key, in which case traffic goes straight to the provider. You can also point ByteAsk at your own OpenAI-compatible server, including vLLM, Ollama, llama.cpp, LM Studio, TGI, SGLang or a LiteLLM proxy.
Does it count against my plan if I run my own model?
No. Self-hosted models are never metered by ByteAsk and do not count against your plan. With your own key, the traffic does not pass through ByteAsk at all.
Can it invent a register offset or a rule number?
The reference tools do not answer from model memory. They search a curated corpus of standards and datasheets and return the exact passage with a citation, and when there is no match they say so instead of guessing. That covers the class of fact that is hardest to check by eye: register offsets, MISRA and AUTOSAR rule numbers, MSR addresses and wire-protocol field offsets.
How much does it cost?
The Free plan is $0. Pro is $16 a month billed annually, or $20 billed monthly. Team is $40 per seat per month, and Enterprise, including on-prem, is priced on contract. Self-hosted models are not metered.
Can we run it inside our own network?
Yes, on the Enterprise plan: on-prem deployment including air-gapped networks, company API keys through a ByteAsk gateway in your network, SSO, SCIM, audit logs and IP allowlisting.
Which editors does it work in?
VS Code, Cursor, JetBrains IDEs, Neovim, Emacs and Zed, plus Windsurf and VSCodium through Open VSX. Every connector needs the byteask CLI on your PATH, since the editor plugin drives the same CLI.
