Headroom is a desktop app for developers who use AI coding agents: programs such as Claude Code and ChatGPT Codex that read files, run commands and write code with a large language model. Every turn of such an agent sends text to the model, counted in tokens (pieces of words, the unit in which AI providers measure use and set limits). Most of that text is machine output: logs, search results, JSON. Headroom runs a local proxy, a small server on the developer's own computer that receives each request before it goes to Anthropic or OpenAI. The proxy shortens the noisy parts and forwards the smaller request. The company says this saves about 50% on the noisy items and typically 25% to 50% across a session.
Two parties built the product. The compression engine is the Headroom CLI, an open-source project created by Tejas Chopra and published under the Apache 2.0 license, a permissive license that allows anyone to use, change and sell the code if they keep its copyright and license notices. The desktop app is the work of Garm Lucassen and his Amsterdam company Garm Tech B.V. (Chamber of Commerce number 99602075). Its code is public on GitHub under the MIT license with the copyright line "Garm Tech BV". Lucassen wrote on AppSumo that he asked the engine's creator for an installable app, and that the creator told him to build it himself and to use the Headroom name. He shipped version 1 on 1 April 2026.
TrustMRR, a site that reads revenue directly from a startup's payment provider, shows US$2,025 in monthly recurring revenue (MRR, the subscription revenue that repeats every month, with a yearly plan counted as one twelfth of its price) from 222 active subscriptions on 25 October 2026. The payment provider is Polar. Verified revenue was US$2,540 in June 2026, fell to US$1,542 in August, and rose to US$2,284 in September and US$2,620 in the first 25 days of October. This page grades every number and shows four failed companies that sold developers a paid improvement to a tool owned by someone else.
How much revenue does Headroom make?
Each row shows the evidence grade and the source numbers from the list at the end of this page. The grades are explained in How Aiolum verifies.
| Fact | Value | Grade | How we know | Sources |
|---|---|---|---|---|
| Monthly recurring revenue, 25 October 2026 | US$2,025 | A | TrustMRR snapshot; revenue last synced 25 October 2026 from Polar through an API key. This is the headline number. It is 1.25% above the site's floor of US$2,000 a month (calculated). | [1] |
| Active subscriptions, 25 October 2026 | 222 | A | TrustMRR snapshot from the payment records. | [1] |
| Average MRR per active subscription | about US$9.12 a month | calc | Calculated: 2,025 divided by 222 equals 9.12. The average is above the Pro price of US$3 to US$4 a month, so some subscribers are on the Max plans. | [1, 2] |
| Run rate from the MRR | US$24,300 a year | calc | Calculated: 2,025 times 12. | [1] |
| MRR growth in the last 30 days | +43.4% | A | TrustMRR snapshot. | [1] |
| Verified revenue, April and May 2026 | US$336 and US$538 | A | TrustMRR monthly timeline. March 2026 shows US$0. | [1] |
| Verified revenue, June 2026 | US$2,540 | A | 4.7 times May (calculated). The home page then offered 50% off all paid plans as founder pricing, and the app had added ChatGPT Codex. | [1, 14] |
| Verified revenue, July 2026 | US$2,251 | A | 11% below June (calculated). | [1] |
| Verified revenue, August 2026 | US$1,542 | A | 39% below June (calculated), and below the site's floor of US$2,000 a month. | [1] |
| Verified revenue, September 2026 | US$2,284 | A | 48% more than August (calculated). The founder-written profile says the AppSumo lifetime deal launched this month; AppSumo bills those sales itself. | [1, 5] |
| Verified revenue, 1 to 25 October 2026 | US$2,620 | A | A partial month, already 3% above June (calculated). At the same daily rate the full month would be about US$3,249 (calculated: 2,620 divided by 25, times 31). The daily table shows US$493 on 1 October; no source explains it. | [1] |
| Verified revenue, last 30 days to 25 October 2026 | US$3,198 | A | TrustMRR gives +80.2% against the 30 days before. A second snapshot on the same profile says US$3,240. The 30 daily values on the profile add up to US$3,199 (calculated). | [1] |
| Verified revenue, all time | US$12,111 | A | The monthly timeline from March to October 2026 adds up to the same US$12,111 (calculated). 55% of it came in the last 3 months (calculated: 6,601 divided by 12,111). | [1] |
| Payment provider | Polar | A | TrustMRR reads the revenue from Polar through an API key and marks it "Merchant of record: No". The terms of service name Polar as the payment processor for subscriptions. AppSumo purchases are billed by AppSumo under the terms, so they are probably not in these figures. | [1, 5] |
| Company behind the app | Garm Tech B.V., Amsterdam, Chamber of Commerce number 99602075 | C | Named in the terms of service and the privacy policy, and on garm.com with the same number. A B.V. is a Dutch private limited company. The number was not checked in the Dutch business register. | [5, 6, 10] |
| Founder | Garm Lucassen | C | He signs the AppSumo launch letter "I'm Garm, founder of Extra Headroom" and is the author of every post on the company blog. The TrustMRR founder handle is garmdotcom, the name of his company site garm.com. | [7, 11, 1, 10] |
| Team size | 1 person | C | Founder-written field on TrustMRR. The AppSumo listing gives the company size as the range 1 to 10. | [1, 7] |
| Outside funding | none stated | C | TrustMRR (founder-written) and the AppSumo listing both say Bootstrapped. | [1, 7] |
| Who built the compression engine | Tejas Chopra, Headroom CLI, Apache 2.0 | B | The company's own pages name him as the creator and say the app was built with his endorsement. The engine repository, headroomlabs-ai/headroom, was created on GitHub on 7 January 2026, carries the Apache 2.0 license with the notice "Copyright 2025 Headroom Contributors", and had 77,809 stars on 25 October 2026. | [3, 4, 9] |
| Who built the desktop app | Garm Tech B.V., MIT license | B | The repository gglucass/headroom-desktop was created on 30 March 2026; its license reads "Copyright (c) 2026 Garm Tech BV". It had 621 stars on 25 October 2026. The README says the shell is open source but the app needs a Headroom account and a paid plan to run. | [8] |
| Does the license allow selling the app? | yes | B | From the license text in the engine repository: Apache 2.0 allows commercial use and redistribution of the engine if the license and notices are kept, and it does not grant use of a trademark. The founder says the engine's creator asked him to use the Headroom name; the site credits him in every footer: "powered by Headroom by Tejas Chopra". | [9, 7, 2] |
| First version | 1 April 2026 | C | Founder's AppSumo letter. A Wayback copy of the home page from the same day shows a macOS download, Claude Code only, and paid plans from US$5 a month billed yearly. TrustMRR gives 27 March 2026 as the founding date. | [7, 13, 1] |

How to read this table: a grade A value was read by TrustMRR from the company's payment provider, Polar, or from Google Search Console. A grade B value is visible in public code or was stated by an independent party such as AppSumo. A grade C value is a statement by the company or the founder. A "calc" value was computed on this page from the rows above it.
| Plan | Per month, billed yearly (US$) | Per month, billed monthly (US$) | Limit |
|---|---|---|---|
| Free trial | 0 | 0 | 7 days of use, no card |
| Pro | 3 | 4 | for Claude Pro or ChatGPT Plus; email support |
| Max x5 | 15 | 20 | for Claude Max x5 or ChatGPT Pro x5 |
| Max x20 | 30 | 40 | for Claude Max x20 or ChatGPT Pro x20; priority support |
| Team & Enterprise | custom | custom | shared controls, private deployment |
| AppSumo Lifetime Tier 1 | 29 one-time | 29 one-time | Pro level, 1 user license |
Each plan matches the customer's AI plan: Pro for Claude Pro or ChatGPT Plus, Max x5 for Claude Max x5 or ChatGPT Pro x5, Max x20 for Claude Max x20 or ChatGPT Pro x20. Yearly billing is 25% cheaper than monthly billing. The trial gives 7 days of use within 14 calendar days and needs no card; there is no free plan after it. At launch on 1 April 2026 the yearly prices were US$5, US$25 and US$50 a month and a free plan allowed use with 25% of the Claude plan; the current yearly prices are 40% lower (calculated). AppSumo sells one-time lifetime licenses at US$29, US$99 and US$199 for the three plan levels; AppSumo bills those sales itself.
When did Headroom launch, and how did it grow?
From a first version on 1 April 2026 to verified recurring revenue just above US$2,000 a month in October 2026. Each entry carries its grade.
- 7 January 2026BThe open-source compression engine, Headroom CLI, appears on GitHub. It is published on PyPI as headroom-ai under the Apache 2.0 license. [9]
- March 2026CGarm Lucassen tries to install the engine, fails for an afternoon, and asks its creator for an app that installs with a double click. The creator tells him to build it and to keep the Headroom name. The desktop repository is created on 30 March. [7, 8]
- 1 April 2026CVersion 1 ships for macOS and Claude Code only. Plans: Free with 25% of the Claude plan, Pro at US$5, Max x5 at US$25 and Max x20 at US$50 a month billed yearly, after a 14-day trial. [7, 13]

- 25 October 2026ATrustMRR shows US$2,025 in MRR from 222 active subscriptions and US$3,198 in revenue in the last 30 days. The home page counts 7,719 installs on macOS, Windows and Linux. [1, 2]
Why did Headroom work?
Four causes, in the order they mattered. Each one is a reusable lesson.
Packaging an existing engine
The hard part, the compression itself, was free code by another developer. Installing it needed Python, pip and changes to the agent's settings. The app installs its own Python runtime of about 3 GB, points Claude Code and Codex at the local proxy, and removes every change when the user quits. Customers pay for that installation, the updates and the dashboard, which the FAQ says plainly in its answer to "Isn't this just a paid wrapper around an open-source project?"
Prices tied to the customer's AI plan
Each Headroom plan matches a Claude or ChatGPT plan: Pro for Claude Pro or ChatGPT Plus, Max x5 and Max x20 for the larger plans. The app reads the plan from the connected accounts. A heavy user who pays more for AI also pays more for Headroom, and the company prices each plan as "a small fraction of the subscription it stretches".
Savings the user can see
The app shows the tokens saved in each session and an equivalent value at API prices. The company published a week of production data from 183 users and a blog post on how to state savings percentages honestly, and its terms warn that real savings can be far below the benchmarks.
Search pages and marketplaces
The sitemap lists about 25 articles and blog posts on Claude Code and Codex costs and usage limits, and comparison pages with other token-saving tools. TrustMRR shows 91,453 Google search impressions in 30 days. The founder also lists Reddit, Hacker News and Product Hunt, and the app was sold as a lifetime deal on AppSumo from September 2026.
How it was built
These details come from the public desktop repository, the company's pages and the founder-written part of the TrustMRR profile. The code details are grade B; the rest is grade C. [8, 9, 6, 1]
- A Tauri shell, a few megabytes in size, with a Rust intercept proxy on port 6767 and a managed Python backend on port 6768 that runs the Headroom engine and the rtk tool for shell output.
- The engine routes each block to a compressor by content type: SmartCrusher for JSON, an AST-based compressor for code, and Kompress-v2-base, a text compression model published on Hugging Face. Originals are stored locally so the model can retrieve them.
- Routing is set through an env block in the Claude Code settings file, a provider block in the Codex config file and a managed block in the shell profile, each with a backup before the edit.
- Optional add-ons from other open-source projects: RTK, MarkItDown, Serena, Codebase Memory, Context7, Ponytail, Caveman and Chisle. The README says only tools that run fully on the user's machine are included.
- Subscriptions through Polar; anonymous usage events through Aptabase, crash reports through Sentry and page statistics through Simple Analytics, according to the privacy policy. The founder lists React, Rust, Ruby on Rails and Python in the TrustMRR tech stack.
- Signed and notarized macOS builds; releases for macOS, Windows and Linux are published on GitHub from the same tag.
Tools named in the sources
Each one opens its page in the Tools tab, with every story that uses it.
Who tried this before Headroom, and why did they fail?
Four companies in the Loot Drop database sold a paid improvement to developers or to users of a platform that someone else owned. The values below are from that database and are not independently verified.
Kite DevTool
The promiseAI code completion inside the developer's editor, years before GitHub Copilot.
Why it diedAccording to the database, it never turned free users into enough paying ones, and GitHub Copilot, built on a large language model and on GitHub's own distribution, took the market.
Fig DevTool
The promiseAutocomplete and visual command builders for the terminal.
Why it diedDevelopers used it daily but would not pay much for a terminal improvement, since free alternatives and their own scripts existed. AWS acquired it in 2024.
PostRocket
The promiseBetter reach for Facebook pages through data on when to post.
Why it diedIts value depended on Facebook's API and algorithm. When Facebook changed them and pushed its own advertising tools, the product lost its purpose.
Cushion
The promiseSave consumers money by recovering bank fees automatically.
Why it diedThe database says banks saw it as taking revenue from them and blocked its access to accounts. A service that saves users money at a platform's cost depends on that platform's tolerance.
The failed startups come from Loot Drop, a free database of dead startups, retold here in our own words. Loot Drop describes its entries as AI-assisted summaries of public sources, so these cards carry no evidence grade.
What changed
Before AI coding agents, developers did not pay for model tokens in their daily work. Tools such as Kite and Fig improved the editor or the terminal, and the database records that developers would not pay much for that, because the gain was small and free options existed. There was nothing to save money on.
AI coding agents changed this. A Claude or ChatGPT plan has a usage limit per 5-hour window and per week; one reviewer quoted on the home page writes that on the US$20 a month Claude plan they occasionally hit both limits. The company's home page says that most of what uses up the limit is "the noise your tools pump into every prompt". A tool that cuts that output turns into extra hours of work on a plan the developer already pays for, so a small monthly price is easy to compare with the plan price. The remaining risk is the one PostRocket and Cushion faced: the product lives on top of services owned by Anthropic and OpenAI.
Can one person copy Headroom now?
The pattern, yes, if the author of the engine agrees.
Headroom resells no AI access and no closed code: it packages a permissive open-source engine, with credit and with the creator's agreement according to the founder. Anyone can do the same with the same engine, and Anthropic or OpenAI can build compression into their own agents.
Where it is still open: Many open-source AI tools have the same gap between strong code and hard installation: local speech-to-text, local document search, model routers for small teams. A signed desktop app with clean removal and a clear savings or time dashboard is open in each of them.
- 1Find a popular open-source tool that is hard to install for the people who would benefit from it, and read its license before you start.
- 2Ask the author first, credit the author on every page, and keep the original free path visible.
- 3Sell the parts the free tool lacks: one-click installation, automatic updates, clean removal and a dashboard that shows the benefit.
- 4Price as a small share of the bill that your product reduces, in tiers that match the customer's existing plan.
What could go wrong for Headroom?
The risks are the mirror image of the causes above.
Just above the floor
The MRR of US$2,025 is only 1.25% above the site's floor of US$2,000 a month, and verified revenue was below it in August 2026 at US$1,542. Revenue first passed US$2,000 in June 2026, so the record above the floor is about five months long, with one month below it.
Another person's engine and another company's platform
The compression engine belongs to the open-source Headroom project of Tejas Chopra, and the app only works with Claude Code, Codex and a few other agents. If Anthropic or OpenAI build the same compression into their agents, change their usage limits, or restrict local proxies, the product loses its reason to exist. The terms of service forbid use that breaks Anthropic's or other providers' terms.
What the verified figures cover
TrustMRR reads only the Polar account. AppSumo lifetime licenses, sold since September 2026 at US$29 to US$199, are billed by AppSumo and are probably not in these figures; they also bring no recurring revenue. The team size and the bootstrapped status are founder-written fields.
Savings claims
The home page promises about 50% on noisy items and up to twice the usage. The company's own production week shows 34% less input, and its terms say that results "may be materially lower than any published benchmark" and that usage can even rise.
For sale
The business has been listed for sale on TrustMRR since 21 July 2026 at an asking price of US$199,999, with 4 offers received. A new owner may change the product, the prices or the agreement with the engine's author.
