Bullet
Coding · tested 2026-08-21 · re-test due 2026-11-21 · by the Hlido desk, not the vendor
In short: A free, speed-obsessed coding agent (GUI + CLI) that routes/searches/executes with a tighter loop than the norm — YC-backed, with a headline 95.8% SWE-bench Verified claim you'll want to confirm.

Quick answer
Bullet scores 73/100 (STEADY) on Hlido’s independent, hands-on test (reviewed 2026-08-21). STEADY (73) for a coherent, well-articulated coding agent with sensible efficiency protocols (model routing, targeted search, parallel execution with loop interception), cross-platform GUI+CLI, a free no-key start, and Y
Bullet is a coding agent built around one thesis: keep up with the developer. Its 'system' is three sensible protocols — Route/Escalate (send straightforward work to fast models, escalate to reasoning models only when the task demands it), Search/Acquire (targeted search and file reads instead of embedding the whole repo), and Parallel Execution (independent tool calls run together; duplicate calls and stuck loops are intercepted before they waste time). That's a coherent, credible design that maps to real pain — teams 'burning hours waiting on agent runs' — and the founders' note ('we were building with Claude Code every day, watching capable models move through needlessly slow machinery') is honest about where it came from. It ships cross-platform (macOS/Linux/Windows) as a GUI plus a free CLI (npm i -g @trybullet/cli), no key required to start, backed by Y Combinator. The thing to flag loudly: the site leads with '95.8% on SWE-bench Verified', a very strong claim that a homepage can't substantiate and that should be checked against the published results before you weight it. Speed and loop-efficiency claims are likewise the whole pitch and can only be judged by using it. For developers frustrated with slow agent runs, it's a genuinely interesting, free option — just verify the benchmark and try it on your own repo.
Why STEADY
STEADY (73) for a coherent, well-articulated coding agent with sensible efficiency protocols (model routing, targeted search, parallel execution with loop interception), cross-platform GUI+CLI, a free no-key start, and YC backing. Not higher because its headline differentiators — the 95.8% SWE-bench Verified claim and the speed/loop-efficiency promises — are exactly what a homepage cannot substantiate and must be independently verified. Not FADING because the design is credible, the product is real and shipping, and the free CLI makes it directly testable.

What we saw
1 screenshot captured by the Hlido engine during the reviewed run (run-dc777aea094124d8-codewithbullet-com). Our own captures — not vendor marketing material.
What it does well
- Coherent efficiency design: Route/Escalate (fast model by default, escalate only when needed), targeted Search/Acquire instead of whole-repo embedding, Parallel Execution with duplicate/stuck-loop interception
- Cross-platform GUI (macOS/Linux/Windows) plus a free CLI (npm i -g @trybullet/cli), no key required to start
- Honest, specific founders' note grounding it in real Claude-Code-workflow frustration
- Free to use with no subscription, and Y-Combinator-backed
What it fails at
- Leads with a very strong '95.8% on SWE-bench Verified' claim that the homepage cannot substantiate — needs independent confirmation
- Speed and loop-efficiency are the core pitch but can only be judged by hands-on use, not from the surface
- Crowded category (Cursor, Claude Code, aider, opencode) — differentiation rests on unverified performance
- Maturity/adoption beyond YC backing and star-free landing copy isn't evidenced on the surface
Red flags
- The '95.8% on SWE-bench Verified' headline is a strong, benchmark-topping claim presented on a marketing page — verify it against the published results before weighting it in a decision.
- Speed/loop-efficiency, the entire differentiator, is unverifiable from the surface; benchmark it on your own repository.
Best for
- Developers frustrated with slow agent runs who want a speed-focused coding agent to try for free
- People who want both a GUI and a CLI from the same agent, cross-platform
- Anyone wanting to A/B a routing/parallel-execution approach against their current coding assistant
Not recommended for
- Buyers who need the SWE-bench claim independently verified before adopting
- Teams standardised on a mature coding agent with proven track record and ecosystem
- Users who need enterprise features/support (this is a free, early product)

Aider
speed-focused-new-gui-cli-agent-vs-mature-open-source-cli-agent
aider is a mature, widely-used open-source CLI coding agent with a strong track record; Bullet is a newer, free GUI+CLI agent competing on speed via model routing and parallel execution, with a bold (unverified) SWE-bench claim. Choose aider for a proven, transparent CLI; try Bullet if slow agent runs are your main pain and you'll verify its speed/benchmark yourself.

Independent readiness for agent delegation & transaction. How it’s scored · check live
A coding agent available as a cross-platform GUI and a free CLI (npm i -g @trybullet/cli, no key to start), so its behaviour is directly testable on a real repository. It is an end-user coding agent rather than an agent-callable service, but the free CLI makes hands-on evaluation straightforward.
