Best Developer Newsletters to Advertise In (2026): Audience Figures as Each Publisher States Them

Developer-tool marketers can sponsor TLDR Dev for working software engineers, the Cooperpress weeklies for JavaScript and web developers, Pointer for engineering managers, Console for developers choosing tools, and ByteByteGo for system-design readers. Every audience figure below is the publisher's own, read on 2026-11-04, and the units differ.

Rebuilt on 4 November 2026. The April 2026 edition of this page and the rates and audience figures it printed are retired; every figure below was read on each publisher's own page on 4 November 2026.

Quick answer

• ByteByteGo states over 1,000,000 readers, the largest figure here, and TLDR Dev states 470k subscribers with a 43% open rate. The units differ, so the order is approximate.
• TLDR Dev, Console and the two Bonobo Press titles state the length of the ad you supply. ByteByteGo, Pointer and Bytes state no placement or ad length.
• Devshot is the only newsletter here whose own page says it sells a dedicated send. For the others, ask: "not stated" is not the same as "not offered".

Dupple publishes Techpresso, AIpresso, Devshot, Cyberpresso, Finpresso and MarketingShot, and sells sponsorships in them. Devshot is listed under the same inclusion rule, ordering rule and source standard as the others.

Dupple data: of the 12 newsletters we read for this page on 2026-11-04, 11 state an audience figure on their own pages, 7 state an open rate or an open-rate range, 7 publish a percentage breakdown of their readers by role, seniority, experience or location, and 1 says it sells a dedicated send.

daily.dev Digest: newsletter ads inside a developer platform

daily.dev's business page sells newsletter ads as "a one-week slot inside the personalized daily.dev Digest", beside five other ad products, such as in-feed ads and sponsored content. "Millions" of developers and "1 in 50 developers worldwide" describe the platform, not the newsletter.

Pros

• Targeting by tag (800+ languages, frameworks, tools and topics), seniority and region is stated.
• Six ad products are described, including the Digest slot.

Cons

• No Digest subscriber count or open rate appears on its pages.
• Newsletter ads sit under "In every plan" of a managed monthly plan (Starter, Growth, Scale).

Developer newsletters with no sponsor page on their own site

We found no sponsor or advertising page on these sites on 2026-11-04. That is not the same as "does not sell"; ask the publisher.

• Hacker Newsletter states "60,000+ tech professionals" on its home page.
• Software Lead Weekly states "Join 31,020 readers" on its home page.
• Refactoring states "170,000+ engineers and managers" on its About page.

Newsletters that do not sell sponsorships

The Pragmatic Engineer's sponsor page says its newsletter, website and socials take no sponsorship or partnership, and its podcast has limited options. It states more than 1 million subscribers. The page recommends other newsletters, among them TLDR, ByteByteGo, Pointer, Programming Digest, Tech Lead Digest (whose address now leads to Leadership in Tech) and Bytes. That list is its author's opinion, not our evidence, and none of our figures come from it.

Who reads developer newsletters?

Dupple data: among post-signup quiz respondents with an Engineering & Software Development role (any industry), 30.3% are decision-makers (Founder, C-Suite or Director/VP), 38.3% work at companies of 51+ employees and 34.9% are in the US, of those with a known country. The sample is 9,078 respondents, answered between 2026-08-05 and 2026-11-03: new subscribers across all Dupple newsletters who answered the quiz right after signing up, not one newsletter's list. More is on Dupple's advertise data page; AI news for developers covers what developers read on AI.

Does list size matter for developer audiences?

Not in proportion. In Dupple's Beehiiv data, read 2026-11-01, Devshot's click-to-open rate is 4.4% and Techpresso's, on a much larger list, is 2.7%. Across six lists from one operator, click-to-open falls 2.1x as list size grows. Six lists show direction, not an industry rule, but a bigger stated audience does not buy clicks one-for-one.

When a newsletter is the wrong channel

Dupple's guide to promoting a devtool puts open-source distribution and documentation first and selective paid newsletter placements fifth. Toolradar's guide to advertising to developers, updated October 22, 2026, calls Hacker News Show HN "not paid but high-intent; worth a polished launch".

For steady presence instead of one send, daily.dev sells in-feed native cards and writes that "reach built on a habit compounds; a one-off burst does not", which is the vendor's claim, not our measurement. Security vendors can start from the cybersecurity newsletters guide; buyers who prefer a platform can read newsletter ad marketplaces compared.

How we picked and ordered this list

• Candidates came from the newsletters The Pragmatic Engineer's sponsor page recommends, the developer newsletters named in our guide to promoting a devtool, and the shortlist behind this rebuild.
• Inclusion rule: a newsletter is listed when its publisher describes its readers as software developers, engineers or engineering leaders and its own site has a page that sells sponsorships or advertising. Newsletters that fit but have no such page, or take no sponsors, have their own sections.
• Ordering rule: by the largest audience figure each publisher states for that newsletter on its own site, largest first; equal figures go alphabetically, and a newsletter with no stated figure comes last. Units differ (subscribers, readers, developers), so the order is approximate.
• Techpresso is not admitted: its own page describes "tech professionals, founders and executives", so it sits in best tech newsletters to advertise in. Devshot is admitted because its page says "software engineers, DevOps, tech founders and CTOs".
• Figures are as stated by each publisher on 2026-11-04 and are not audited by us. We re-read every quarter. See the editorial policy.

What we could not verify

• Competitor audience figures are self-reported by each publisher. Our subscriber figures come from Beehiiv and our quiz figures from self-reported post-signup answers; no third party audits either.
• Open rates are not comparable across platforms: each platform counts opens differently, and Apple Mail privacy protection inflates them. Bonobo Press reports "unique" open rates and Cooperpress "net" ones.
• Five publishers' own pages disagree with each other (Pointer, Cooperpress open rates, Leadership in Tech, Programming Digest, Tech Manager Weekly); we print both figures.
• The Cooperpress advertise page is marked "Last updated: October 2021".
• ByteByteGo says "readers" and Bytes says "developers" without defining the unit. Tech Manager Weekly's stats are animated counters, so we read their target values in the page HTML.
• daily.dev publishes no Digest subscriber count. Software Design: Tidy First?, which The Pragmatic Engineer recommends, has no sponsor or advertising page on its site (none found on 2026-11-04), so it is not listed. We did not read iOS Dev Weekly or Android Weekly.
• "Not stated" for a dedicated send or ad format means the page does not say, not that the publisher declines.
