Coding Agents Scoreboard (Aug 2026)

100xprompt

The vendor positions this as sovereign AI infrastructure — meaning the compute, the model, and the data all stay inside your perimeter, whether that perimeter is a company server room or a national-scale government network. The CLI agent handles autonomous coding and deployment tasks without phoning home. Self-hosting is supported, and the API gives your internal tooling a direct integration point. Where this model shows strain is ecosystem breadth: the scraped page content does not surface an established marketplace of pre-built integrations, so teams arriving from richer SaaS ecosystems will build more plumbing themselves. The freemium tier exists, but enterprise-grade air-gap deployments will hit paid-only features quickly.

ClaudeThings

Running inside Claude Code via a single npx command, ClaudeThings drops 89 agents, 103 skills, and 181 slash commands into any project — split across an engineering kit and a marketing kit that share the same project context. The tech-lead agent plans and delegates; specialists like react-specialist, golang-pro, and security-auditor execute in their lanes; the marketing side handles everything from SEO audits to launch-day campaign briefs. Because agents read a CLAUDE.md you fill in once, stack-specific conventions carry through every task without re-prompting. The ceiling appears when your workflow needs to step outside Claude Code — there is no API, so external pipeline integrations require a different tool.

Command Code

The agent runs in three modes — interactive CLI, headless with a prompt flag for scripted pipelines, and a background sandbox — so it fits scheduled jobs as well as live coding. Learned preferences compile into reusable skills automatically; no rules to write by hand. The team collaboration angle is real: one command pushes your taste profile, the whole team pulls it. Where the walls appear is less documented: open-model tool-calling support is a stated differentiator, but teams hitting complex multi-step agentic chains on open models will need to validate those claims against their specific stack before committing production workloads.

Forall

Forall is an Apache-2.0 CLI agent from Astrio that generates spec-driven code alongside machine-checkable proofs, running entirely in your terminal or wiring into Cursor, Claude Code, or Codex via MCP. You describe what the code must do; the agent produces both the implementation and a formal proof you can verify independently. The verification step is not optional decoration — it runs against the spec, so a failing proof surfaces a real logical flaw before the code ships. The docs describe Rust, TypeScript, and Java as the supported targets, which covers a specific but meaningful slice of production codebases. Teams outside those languages hit a hard wall.

Boffin

Boffin sits between your codebase and agents like Cursor, Claude Code, or Codex, feeding each edit the specific rules that apply to that file rather than a flat global prompt. The GitHub page describes it as a staff-engineer control layer: it enforces verification steps after code changes and routes constraints designed to protect existing test coverage and API contracts. It ships via npx boffinit, carries an MIT license, and has no hosted API or agent logic of its own — it controls agents, it does not become one. Where it shows limits: if your team needs dynamic rule generation or the constraint set grows complex enough to require its own maintenance cycle, you are now managing a rules system on top of your codebase. Teams that reach that ceiling tend to bake the constraints directly into their CI pipeline instead.

Noter

noter runs as a CLI-installed tool with a four-panel working surface called Mission Control: notes, suggestions, context, and prompts, kept visible alongside whatever your agent is doing. The separation between planning mode and execution mode is the core design bet — noter treats them as distinct activities that should not collapse into each other. Notes and agent context tracking are free forever. The spec-to-prompt pipeline (Blueprint) and the suggested tasks and prompts panels are paid-only features. Teams doing ad-hoc agent work will get real value from the free tier; teams running spec-driven projects with multiple implementation phases are the ones who need Blueprint.

Bohay

The tool gives you a single interface to watch every agent's real status, not what the CLI reports but whether the process is actually doing work. File leases prevent overlapping edits before they're even assigned; isolated git worktrees keep agents from colliding on the same checkout; a test gate must pass before a task merges. Sessions survive terminal restarts, and each agent reloads its own chat history without you repasting flags. The orchestration board tracks dependencies so tasks wait for upstream work to clear the quality gate before they start.

Bothread

Bothread runs locally on your machine and coordinates MCP-compatible agents — Claude Code, Cursor, Gemini CLI, Codex, and others — on a single codebase through a shared room where agents claim files before editing them. You watch the live thread of agent activity and can pause, redirect, mute, or remove any agent mid-task. An optional approval gate lets you sign off before any action flagged as risky proceeds. The coordination layer calls no models itself and requires no API keys — it only manages the agents you are already running. The ceiling appears when your project requires agent tooling that does not speak MCP: any agent outside that protocol sits outside Bothread's coordination entirely.

improv.sh

improv operates as a task harness: the @im call pulls repo context, detects your test commands, writes acceptance criteria, and packages shell validation steps into one spec the agent can implement on turn one. The loop infrastructure is the distinguishing piece — judges run your actual exit-code commands (npm test, typecheck, build), so done means your tests pass, not that the agent says it's done. The tool installs locally via curl with no external API keys required, and the Chrome extension brings the same engine into web-based chat interfaces. The 920-skill library and daily auto-research loop suggest the routing layer will keep growing — but the page offers no independent benchmarks to validate the token-savings figures cited.

mindwalk

The tool replays Claude Code or Codex session logs against a spatial model of your repository, showing file touch history, exploration paths, and where the agent's footprint diverged from the intended task boundary. Everything runs locally as a compiled Go binary — no server, no API key, no data leaving the machine. That local constraint is also the ceiling: Mindwalk reads and visualizes; it does not flag anomalies automatically or integrate into a CI gate. Teams using it for post-session audits get a fast, honest picture of agent behavior. Teams that need automated alerts or diff-level review stay in their existing toolchain.

VibeRaven

VibeRaven scans a repo against a production-readiness checklist covering auth boundaries, billing flows, database migration state, deployment config, and monitoring — then generates a focused prompt for the next coding-agent session based on the specific evidence gaps it finds. The distinction it enforces is useful: changes the agent can make in the repo versus dashboard actions that require a human to touch Stripe, Vercel, Supabase, or Clerk directly. The docs describe a freemium hosted scanning interface with a free scan limit, plus an npx CLI path for local runs. Where it breaks is scope — VibeRaven reads repo evidence and provider configuration signals, but it does not run your app or simulate live traffic, so gaps that only appear under real request conditions are outside its detection range.

AI-factory

The repo structures the AI coding workflow around specs, roles, skills, agents, and hooks — all defined in config, not scattered across prompt files. An adversarial review bench pits agents against each other before code reaches a human, and deterministic gates block merges when quality checks fail. This fits teams already running Claude Code or similar agents who want repeatable process rather than one-off prompt magic. The toolkit is early-stage — five commits, zero open issues — which means the primitives are present but the community-tested edge cases are not. Teams pushing beyond the documented patterns write their own skills and roles, which is supported by the model but undocumented territory.

Baton

Baton sits in your menu bar and polls the signals your machine already produces — no manual logging, no clipboard tricks — to show you which AI coding sessions are mid-run and which have handed the decision back to you. The core metaphor is the 🎽 icon: the baton is with the agent, or it's with you. Click the menu, see the queue, jump straight to the session that needs a response. This is a local Python app, MIT-licensed, installed via a shell script, and it runs entirely on your machine. It works with Claude Code and Codex threads on macOS — nothing else, and no roadmap to something else is documented.

Caveman

The vendor claims roughly 65% token reduction across four compression layers — proxy, memory, code, and eval-gated rollout — without altering the bytes the model actually sees. Caveman Code is a terminal agent that plans before it ships, running one autonomous loop across 20+ providers at roughly half the token cost of comparable agents. Cavemem adds a local SQLite store with full-text search and a vector index over MCP, so agents recall prior context instead of re-sending it. The cloud gateway, which would extend these savings across any LLM traffic via a base URL swap, is waitlist-only — it is not available yet. Teams who need the proxy layer today are blocked.

CodeTrain

CodeTrain runs a Socratic tutor against your actual repo: it breaks work into small steps, makes developers type every line themselves, and reviews what they wrote without handing over the answer. The local-first free tier keeps code on the machine; the managed tutor sends submitted snippets. A lightweight profile tracks gaps and resurfaces them later through spaced repetition, so a developer who struggled with your auth pattern sees it again before it bites them in production. The team dashboard lets a manager see finished lessons and concept coverage per developer. The ceiling arrives quickly for teams that need structured, multi-week curricula with custom assessments beyond what the Socratic loop can generate.

DiffForge

The tool runs Codex, Claude Code, and OpenCode side by side in local terminals, with a kernel that leases files so concurrent agents cannot touch the same path at once. Loop Spaces add scheduled blueprint graphs — think cron jobs, but the steps are agent handoffs and verification scripts rather than shell commands. Voice dictation runs locally via Whisper or through the cloud, and screen snips can be dragged directly into a prompt, so you can point at a bug rather than describe it. Token usage and credit events stay visible per provider in real time, which matters the moment you are running three agents against three different API accounts simultaneously. The self-hosted option keeps code on your machine — only commands travel over the wire.

Flightwake

The framework installs into a git repository via npx and writes pure Markdown records that live in version control alongside the code. There are zero runtime dependencies — no sidecar process, no external service, no database to stand up. The design targets agents like Claude Code that run multi-step coding sessions where state bleeds across multiple handoffs; the records become the handoff. The ceiling appears fast for teams who want queryable logs, dashboards, or structured telemetry: Flightwake writes Markdown files, full stop. Teams who outgrow flat-file observability wire a separate log aggregation layer and end up maintaining both.

Godcoder

Godcoder runs entirely on your machine, routes API calls only to whichever LLM provider you supply a key for, and keeps no vendor backend in the loop. The project's headline behavior is a self-building agent harness: the agent writes and refines its own scaffolding as it works, rather than operating inside a fixed framework you configure once and maintain forever. That loop is compelling in early experimentation — and it's also where the unknowns live. The repo is young, documentation is sparse, and the self-optimizing harness is precisely the kind of behavior that's hard to audit in production. Teams who need deterministic, reviewable agent behavior before shipping to users will hit that wall quickly.

Grinta

Grinta runs the full plan-execute-validate-finish loop on your own machine, touching no external cloud plane. You point it at a task, it breaks the work down, writes and runs code, checks its own output, and delivers a finished result — all without leaving your environment. The project is MIT-licensed and ships with Docker support and a devcontainer config, so teams can drop it into an existing setup without fighting environment drift. It is at release-candidate status, which means the core loop is stable enough to test but the API surface and configuration contracts are not frozen. Teams running this against production-grade complexity should expect to carry the maintenance burden themselves.

Grok Build

Grok Build is xAI's terminal-native coding agent: a full-screen TUI that reads your codebase, edits files, runs shell commands, searches the web, and tracks long-running tasks in a loop. It runs interactively for keyboard-driven sessions, headlessly for scripted pipelines, and embeds into editors via the Agent Client Protocol. The open-source, Apache-2.0 codebase is written in Rust and self-hostable. Where it earns trust is in environments where a GUI agent would require a workaround — shell scripts, CI jobs, editor plugins. Where it starts to show limits is in anything requiring a visual interface, fine-grained permission controls per task, or an API surface you can call programmatically.

Hanesu

The project borrows from Harness Engineering principles: work is broken into phases with task files, role handoffs, quality gates, and progress artifacts written to disk. Agents using runtimes like OpenCode, Codex, or Claude Code run through that structure rather than a monolithic prompt. The vendor explicitly flags this is not for small, obvious edits — a direct prompt is faster there. Where it earns its place is multi-step refactors, security-sensitive changes, or bugfix workflows where you need the agent to stop, surface what it found, and wait for your sign-off before proceeding.

Jacquard

Jacquard is a small programming language with a surface syntax (.jac files), an OCaml type-checker, a CPS interpreter, and a C-emitting AOT backend — the full stack for running, reviewing, and simulating model-written programs. Its core differentiator is language-level effect tracking: the runtime can surface what a program touches and what authority it claims before you let it run. The Warp tool lets you execute code against multiple simulated or real worlds, which means policy and risk scenarios become testable rather than theoretical. The project is Apache-2.0 licensed with free binaries and a self-hosted install path. This is a research project — the community is small, the ecosystem is thin, and production support does not exist.

Makoto

Makoto hooks into Claude Code's event stream and audits each assertion — test results, citation matches, commit records, certificate claims — against a ledger of what the agent actually did, not what it reported. The vendor states the design targets zero false positives, meaning Makoto blocks on confirmed fakes rather than flagging on suspicion. That precision matters in CI gates where a noisy checker gets disabled within a week. The tool is reactive, not autonomous: it sits between agent action and downstream consequence, checking receipts. Teams without Claude Code in their stack have nothing to hook into — this is not a general-purpose verification layer.

Overplane

Overplane is a free, open-source CLI binary that wraps Claude Code, Codex, or OpenCode in container isolation, spec-driven builds, and Z3 formal verification before a single line of code is written. Every agent run executes in a locked-down container with a restricted view of the host system, so a bad outcome means deleting a sandbox, not restoring a backup. Builds are content-hashed and content-addressable, which means you can replay any build down to a single spec and see the normalized dollar cost attached to that run. The ceiling appears early in teams who need the tool to also do its own code generation — Overplane is a build wrapper around agents you already own, not a coding agent itself.

Tau

Tau is a small Python coding agent structured as a three-layer curriculum: a provider-neutral streaming layer, a reusable agent harness, and a coding environment with file tools and a terminal UI. The vendor describes every moving part as readable source — no abstraction you cannot trace. Sessions persist as JSONL under ~/.tau/sessions, supporting resume and branching. The tool is explicitly educational and at v0.1; teams looking for a production coding assistant will hit its ceiling immediately. The architecture lesson is the product — once that lesson lands, contributors extend or replace layers to build their own agents.
