GRACE A plugin for Claude Code on Mac and Windows.

Test result
Measured against Claude Code with two token-saving plugins already installed: caveman and context-mode.
Read from the limit in whole percentage points, two measurements added up: 32 % with Grace 0.3.8, 63 % with Claude Code + caveman + context-mode · 60 tasks, Claude Max 20x on both sides · October 2 – 3, 2026: 30 tasks at the same time on two accounts, 30 with the comparison run measured separately on the same day · on the comparison account 54 s of readings are missing at a 5-hour reset, which can only make the saving look smaller
5-hour limit used for the same 60 tasks
lower is better
Quality: hidden criteria met
higher is better · the 58 tasks both runs finished
| Measure | Claude + caveman + context-mode | With Grace |
|---|---|---|
| 5-hour limit used for the same 60 tasks | 63 % | 32 % |
| Quality: hidden criteria met | 91.9 % | 92.5 % |
≈ 96–100 % more work in the same limit
Calculated from the limit value above: ≈ 96 % more. On 43 of the 58 tasks both runs finished, at least twice as much: 2.0× to 4.4×, calculated from Claude’s cost per task (quality on those: 94 % with Grace, 93 % Claude alone). 2 more such tasks are not counted because of their quality (45 % with Grace, 93 % Claude alone).
49 % less time
Measured at the same time with Grace 0.3.8 (October 3, 2026): 3 h 41 min with Grace, 7 h 10 min Claude alone — the time of all 30 tasks, added up. Grace was faster on 28 of them; quality: 93 % with Grace, 90 % Claude alone. Only the 30 tasks measured at the same time are compared on time; the other 30 were measured separately.
2,013 valid runs, Sep 13 – Oct 3, 2026, while we built Grace; earlier series used development versions. That shows how much we tested, not the saving: the result above comes from the two tests of October 2 – 3, 2026 with Grace 0.3.8, 60 tasks on Claude Max 20x.
Work per 5-hour window, calculated · Pro = 1×without → with Grace
5× → 9.8 to 10×
the test ran on this plan
20× → 39 to 40×
1× → 1.96 to 2×
Calculated from the Max 20x test; Pro and Max 5x use Anthropic’s plan multiples. How the ranges are calculated
One command in Terminal (PowerShell on Windows). It signs your computer in, checks your subscription and asks before it installs anything.
No command, no new workflow. Grace sees whether it is a new project or work on an existing one: a new project it builds in your projects folder (the one you name during setup), next to your other projects, and says so; changes to existing projects it takes over as well. Say “without Grace” and Claude does it alone.
In our test the same tasks used less of the 5-hour limit. Quality was measured too — both are shown above.
Grace switches none of them off — they keep working in your Claude Code session. New projects Grace builds follow your CLAUDE.md rules, without your other plugins. Your deny rules (permissions.deny) apply to Grace too. A few plugins bring their own file-editing tools and compete with Grace; /grace:grace-plugins shows whether you have one.
It contacts us only to sign in your computer, download Grace and check your subscription. Claude sees what it needs, as it does without Grace.

Not on average. On the 58 tasks both runs finished, Grace 0.3.8’s results met 92.5 % of the hidden acceptance criteria, Claude alone 91.9 %. Single tasks went either way. On 2 of them Grace was clearly worse (more than 10 points below Claude alone): 5 % vs 86 %, 86 % vs 100 %. Quality, level by level
Against Claude with the token-saving plugins caveman and context-mode, not against bare Claude — on the same 60 tasks. A saving against that is a saving on top of what careful users already do. How we measured Token savers, measured
A Mac with Apple silicon or a PC with Windows 10 or 11, and Claude Code with your own Claude Pro or Max plan — or the Claude API on the API plan. Grace does not replace your plan. The installer adds Node.js if it is missing.
Run the install command from the download page in your Terminal (PowerShell on Windows). It signs this computer in, checks your subscription, installs what is missing and updates Grace — the same after reinstalling Claude Code or on a new computer. Then restart Claude Code. If 2 computers are already signed in, remove one in your account first. If something is missing later, /grace:grace-einrichten in Claude Code checks and fixes it. Install Grace
Yes, anytime. Grace runs to the end of the period you paid for. You can withdraw from the contract within 14 days and get your payment back in full, even if you have already downloaded Grace. The withdrawal notice gives the exact period; once it has ended, payments are not refunded.
Usually under 2 minutes if Node.js is already installed (our estimate).
Installing Grace needs an active subscription — or your free first month.
