Route work by task complexity
Bullet routes straightforward work to fast models and escalates only when a task requires deeper reasoning. The intent is to keep agent runs aligned with the urgency of the job.
Bullet
Bullet is a terminal-based coding agent for macOS and Linux that routes, searches, and executes work with a leaner agent loop. The public site says it is free to use during private beta and highlights targeted search, parallel tool execution, and loop interception.
Overview
Bullet is a coding agent built around speed and a compact workflow. The homepage positions it as a tool that “routes, searches, and executes” to keep pace with the developer instead of adding overhead around the model.
The public site emphasizes a leaner agent loop: route straightforward work to fast models, search the repository selectively, run independent tools in parallel, and stop loops before they consume time. Bullet is presented as a CLI for macOS and Linux, with a free-to-start private beta and no subscription on the site at the time of capture.
Core capabilities shown on the site
Search and read only relevant code
The site says Bullet uses targeted search and file reads to find relevant code instead of embedding an entire repository. That approach is presented as a way to focus on the files that matter.
Parallel execution with loop interception
Bullet runs independent tool calls in parallel rather than queueing them. The homepage also says duplicate calls and stuck loops are intercepted before they waste time.
Terminal-based CLI workflow
The homepage shows Bullet running in the shell as a CLI and provides an install command for macOS and Linux. It is presented as the same agent loop as the earlier product, but in terminal form.
Published benchmark run and artifact set
The benchmark page states that Bullet uses its production harness with the exact agent loop it ships, including targeted search, parallel tool execution, and loop interception. The result page also documents a single-attempt SWE-bench Verified run.
Where Bullet fits
Fast implementation in the shell
Use Bullet when you want a terminal-based coding agent that can take actions without waiting on a heavier IDE-style workflow. The product page frames it as a way to keep up with fast-moving ideas.
Parallel code investigation and execution
Use Bullet for tasks that can be split into smaller, independent actions, since the site explicitly highlights parallel tool execution. That includes work where search, file reads, and verification can happen together.
Mixed-complexity agent tasks
Use Bullet when a task starts with straightforward changes but may need escalation for harder reasoning. The routing flow is designed to send simple work to faster models and reserve heavier reasoning for more complex steps.
Benchmark-driven evaluation
Use Bullet if you want a public benchmark trail before trying the product. The site publishes a SWE-bench Verified results page with methodology, counts, timing, and an artifact set.
Pros and Cons
Pros
- Uses targeted search and file reads instead of relying on whole-repo embedding, which can keep context narrower.
- Runs independent tool calls in parallel and says it intercepts duplicate calls and stuck loops.
- Available as a CLI for macOS and Linux, with Node 18+ noted for the shell workflow.
- The site says it is free to use during private beta, with no subscriptions required.
- Includes a public benchmark write-up with method details, including a single-attempt SWE-bench Verified run and published artifacts.
Cons
- The pricing page at /pricing returns 404, so public pricing structure and plan limits are not available from the source.
- The site does not provide a public integrations list or a detailed compatibility matrix.
- Some product details are still high level on the homepage, so workflow depth is clearer in the benchmark post than in the main product page.
FAQ
How do I use Bullet?
Bullet is a coding agent that runs in a terminal-based workflow rather than a browser or full IDE. The homepage shows a CLI command for installation on macOS and Linux, with no key required to start.
What does Bullet cost?
The public site says Bullet is free to use during private beta and that there are no subscriptions. The pricing page at /pricing currently returns a 404, so no plan details are available from the source content.
What platforms does Bullet support?
The source text lists macOS and Linux on the homepage, and the CLI section specifically says Bullet runs in your shell. The site also states Node 18+ is required to start using the CLI.
What does Bullet do differently from a typical coding agent?
The homepage describes Bullet as routing, searching, and executing with a tighter loop: it routes straightforward work to fast models, uses targeted search and file reads, runs independent tool calls in parallel, and intercepts duplicate calls and stuck loops.
Does Bullet list supported integrations?
Bullet's benchmark page says the production harness uses targeted search instead of repo embedding, parallel tool execution, and loop interception. The site does not provide a public integrations list beyond those workflow capabilities.

Vi3ecode is a maintained development environment for working with AI coding agents. It keeps project context, terminal, Git, memory, flows, review, and communication connected around the agent you already use.
CreateOS Sandbox
CreateOS Sandbox is an isolated compute environment for running code and agent workloads inside Firecracker micro-VMs. It is designed for workflows that need machine-level isolation, private networking between sandboxes, and programmatic control through SDK, CLI, or MCP.
hob
hob is an independent workspace for coding agents that keeps agent sessions, terminals, history, and follow-up work organized around the tools and providers you already use. It is aimed at developers who want local control over routing, history, and workspace structure rather than a bundled model stack.
Manta AI
Manta AI is an autonomous web app testing tool for teams that want to map application behavior, catch regressions, and generate tests without writing scripts or maintaining selectors. It works from a URL and supports plain-English test flows, run results with screenshots, and scheduled or deployment-triggered checks.
