Boost

What is Boost?

Boost is a free command-line tool from JFrog that sits between a coding agent and the shell. Agents spend much of their context window reading build logs, test results, git diffs and Docker layers, and Boost compresses that output with declarative TOML filters before the model sees it. Filters are flag-aware, so explicit verbosity flags still return detail, and compression is reversible: a boost retrieve command restores the original output locally. When a filter errors out, Boost passes through the raw output so the command still runs. A single boost init wires hooks into Cursor, Claude Code, Codex CLI, GitHub Copilot and OpenCode, and boost report opens a local dashboard of sessions, token savings and retrieve events. Further features include MCP response compression, file optimization and the early-access BoostGraph code search. JFrog states Boost is free with no signup, credit card or trial timer, and publishes its own benchmark showing about 12% lower cost at the same pass rate.

Use cases

• Cut token use from terminal output in coding agents
• Compress large MCP JSON responses
• Write custom filters for internal CLIs
• Review what each agent session consumed
• Restore original output when a filter hides detail
• Post agent token usage on pull requests

Who it's for

• Developers using coding agents
• Engineering teams
• Platform and DevOps engineers

Why use Boost

• Agents keep failures and summaries while repetitive output is dropped, so context lasts longer.
• Compression is reversible, so nothing is lost if the agent needs the full output.
• Hooks never block a command, falling back to raw output if a filter errors.
• Reports run locally, giving you per-session token and tool-call detail.
• It is free with no signup, so teams can try it without procurement.

How to get started with Boost

1. Run the one-line installer from boost.jfrog.com on macOS, Windows or Linux.
2. Run boost init so the wizard finds your coding agents and installs the matching hook and skill.
3. Work as usual; supported commands are rewritten so that Boost handles their stdout and passes the compressed result back to the agent.
4. If the agent needs more detail, boost retrieve restores the original output locally.
5. Run boost report to open the dashboard and see commands, token savings and retrieve events.

Boost limitations

• BoostGraph is in early access and MCP filters and PR comments are in staged rollout
• Benchmark and savings figures are published by JFrog
• Over a full benchmark run the saving is modest because most tokens are reasoning, not tool output
